Russian vehicles have been equipped with homemade drone-jammer, as reported. In a retaliatory move, the Ukrainians have been employing drones to destroy these jammers.

Ukrainian drones have instilled a sense of fear among Russian marines, and rightfully so. Russian troops are employing various tactics to bring down, neutralize and deflect these dangerous drones.

While improvisation can yield positive results, it is not a foolproof method. It has become increasingly evident that Russian military personnel are equipping their tanks and combat vehicles with small RP-377 radio-jammers, which are designed to impede the signals that trigger radio-controlled roadside bombs, with the aim of obstructing the signals that govern high-speed first-person-view drones.

It is becoming more and more evident that RP-377 is not effective against FPV drones. Social media is filled with darkly-ironic videos that depict Ukrainian drones destroying Russian vehicles that have do-it-yourself drone-jammers installed.

Thematically, the videos exhibit similarities to those illustrating Ukrainian forces obliterating Russian GPS-jammers by means of GPS-guided bombs, as you might have surmised.

A Russian naval infantry brigade, either the 155th or 40th Brigade, faces a challenge with drones, as evidenced by an ungraceful T-80BVM tank. The tank has been outfitted with do-it-yourself cage armor that could hinder the turret's rotation, but it may also provide some safeguard against explosive drones.

Adding to the tank's peculiarity is the RP-377 radio-jammer, which is securely mounted on its rearmost cage armor. Crafted by the Kremlin, this portable jammer
was designed to interfere with enemy communications and provide protection to infantry and vehicles against improvised explosive devices.

The utilization of IEDs presents a major obstacle in Russia's irregular warfare endeavors, particularly in conflict zones like Syria. Conversely, in Ukraine, where the majority of the fighting involves regular forces, the prominence of IEDs is considerably lower.

On the Ukraine front line, more and more Russian vehicles are being equipped with RP-377s attached to their hulls. The purpose of these jammers is unlikely to be the prevention of IEDs. It appears that the Russians are banking on the RP-377s to take down drones.

Radio-jamming poses an equal threat to both remote IEDs and drones in principle. The Russian troops deployed in the Eastern Military District conducted tests in 2020 and reported that their RP-377s played a crucial role in suppressing unmanned aerial vehicles.

It is worth noting that a significant number of drones are equipped with frequency-hopping controls or autopilots, which effectively neutralize the adverse effects of radio-jamming. As a result, there have been numerous instances where drone strikes have successfully targeted vehicles that were equipped with add-on RP-377s.

An ironic incident occurred a few weeks ago when a Ukrainian FPV drone collided with a Russian BMP fighting vehicle that had an RP-377 installed on it.

 

In response to the grave danger posed by pursuing explosive drones, Russia seems to be implementing jamming technology on its tanks as a defensive measure.

On August 2, 2022, DJI Matrice 300 reconnaissance drones were observed conducting test flights in the vicinity of Kyiv. These drones were being prepared for deployment to the front line. The test flights were captured in a photograph taken by SERGEI SUPINSKY/AFP and depict the advanced capabilities of these drones.

SERGEI SUPINSKY/AFP via Getty Images captured the test flights of DJI Matrice 300 reconnaissance drones near Kyiv on August 2, 2022, before they were sent to the front line for deployment.

The visual evidence suggests that Russia is outfitting its tanks and vehicles with jammers designed to disrupt the operation of Ukraine's drones.

The signal jammers are showcased in a video advertisement, while Russian Telegram channels rally together to raise funds for procuring more of these devices for the Russian troops.

Both parties engaged in the Ukrainian war are making concerted efforts to address the challenge presented by drone technology.

Russia seems to be taking measures against the persistent risk of drones exploding by installing cell phone jammer
on its tanks and vehicles.

This maneuver serves as the most recent illustration of electronic warfare tactics employed on the battlefield. Both sides are now escalating their defensive strategies to shield their troops from the ever-increasing threat posed by unmanned aerial vehicles (UAVs). These UAVs pose a significant danger as they relentlessly track and attack main battle tanks, armored vehicles, supply trucks, infantry squads, and even individual soldiers.

This week, a camouflaged tank equipped with a GPS jammers on its roof screen was featured in a photo shared on a Russian Telegram channel. The tank also had a cage designed to shield against first-person view (FPV) drone attacks.

The cone-shaped system has been identified by observers as a Volnorez C-UAS EW jammer. This particular channel had previously posted several pictures showcasing the unboxing and installation of the same drone jammer system on different vehicles, including tanks and pickup trucks.

In addition, a video was shared to promote the system, shedding light on its production process and demonstrating its ability to effectively neutralize Ukrainian drones. It has been reported that Russian Telegram channels have initiated crowdfunding efforts to procure more jammers for utilization by Russian units.

The decision of Russia to equip vehicles with jammers highlights their growing apprehension about the threat of FPV drone attacks. However, the effectiveness of these systems and the number of jammers in use remain uncertain. In the past, tank and armored crews have been seen welding cages onto their vehicles as a crude defense.

Nevertheless, while armed forces strive to implement electronic warfare defenses, both adversaries in the conflict have been actively pursuing the development of jamming-resistant drones. Such cutting-edge technologies may compel apprehensive vehicle crews to explore alternative resolutions.

The field of drone technology is rapidly advancing and presents numerous possibilities across various sectors, such as military operations, public safety initiatives, logistics, and home services. The key attribute of drone technology lies in its ability to operate independently and execute assigned tasks without manual intervention. Additionally, drones offer significant benefits in terms of adaptability and intelligence, as they can automatically adjust to different environments, evade obstacles, and accomplish tasks with flexibility. 

By combining uav jammer and counter-gun technology, the UAV counter-gun system follows a technical principle that enables remote control and counter-gun attacks. This innovative technology allows for customization based on mission objectives, facilitating precise countermeasure gun shooting against specific targets. Furthermore, the UAV countermeasure gun utilizes the UAV's flexibility and intelligence to automatically adapt to different environmental conditions, ensuring precise targeting and effective crime prevention.

Drone countermeasure gun technology holds immense potential across various sectors, particularly in public safety and military arenas. Within the realm of public security, drones can be utilized to conduct thorough investigations of crime scenes, monitor law enforcement operations, swiftly identify criminal suspects, enhance police efficiency, prevent crimes, and curtail their proliferation. In the military sphere, the integration of UAV counter-gun technology can greatly enhance combat effectiveness by facilitating timely detection of enemy forces and accurate implementation of counter-gun shooting, thereby reducing the toll of war.

The emergence of UAV countermeasure gun technology has opened up a vast array of possibilities. Its potential to effectively combat crime, reduce gun-related incidents, and enhance public safety is undeniable. Furthermore, in military operations, the utilization of UAV countermeasure guns can greatly improve combat efficiency, effectiveness, and bolster anti-terrorism endeavors. As technology progresses, drone countermeasure gun technology will undoubtedly make significant strides, offering society and the military even more substantial benefits.

An electromagnetic interference device that resembles a gun is known as a drone countermeasure gun

An event site was unexpectedly invaded by an enigmatic drone, resulting in a substantial disruption to the game's progress. Shortly thereafter, my gaze fell upon a newly introduced apparatus - a silver-gray drone countermeasure gun, measuring around one meter in length, designed to swiftly incapacitate the adversary with a single shot.

The drone remained intact as it gently touched down on the ground. The fundamental principle behind this weapon lies in emitting electromagnetic interference waves spanning from 2.4GHz to 5.8GHz, which effectively disrupts the communication link between the remote control jamming device and the drone. This approach proves highly effective since the majority of drone remote controls operate within this frequency range.

With a range of 1,000 meters, the activated UAV countermeasure gun can effectively manipulate long-distance low-altitude UAVs within the specified "control area". It can compel these UAVs to either descend, return to the operator, or smoothly descend in a short span of time, ensuring efficient control over their flight.

Cell-jamming technology is being employed by the suspects involved in the break-in to effectively elude surveillance cameras and prevent their activities from being recorded.

Devices are utilized in cell-jamming to impede the transmission of radio or wireless signals

CMPD has reported that burglars have managed to outsmart surveillance cameras during certain instances of home break-ins by utilizing advanced technology.

Cell-jamming, also known as signal interference, occurs when an individual utilizes a device to disrupt radio or wireless transmissions.

According to the Federal Communications Commission, the deliberate use of a phone-jammer, GPS blocker, or any other signal jamming device to intentionally block, jam, or interfere with authorized radio communications is considered a violation of federal law. It is important to note that there are no exceptions for using such devices within a business, classroom, residence, or vehicle.

The act of Cell-jamming could be carried out by a device positioned at a distance of approximately 30 feet from the intended target, or by utilizing home cameras.

In a south Charlotte neighborhood, a video has surfaced showing a suspect stealthily navigating through a yard after dark. It is worth mentioning, though, that not all incidents have been documented on camera.

Prompt: Paraphrase the given text

As per John Shocknesse, VP of Customer Operations for CPI Security, wireless devices are prone to interference, and people will always attempt to disrupt their communication, regardless of the network they are on.

In a matter of seconds, a person can be caught on camera, but with the aid of cell-jamming, all it takes is one swift action, such as flipping a switch or pressing a button, to make them disappear or leave no trace behind.

CMPD has highlighted that this matter has arisen in a number of home break-ins in the southern area of Charlotte.

Shocknesse confirmed that they have not come across any instances of the mentioned activity. They are fully cognizant of this matter and are ensuring that they possess the finest and most up-to-date technology, which they believe to be of utmost significance.

WBTV sought his opinion on which electronic devices are more susceptible to cell-jamming.

Shocknesse believes that the issue of encryption arises in wireless devices that are significantly older.

As per his statement, the more recent security and surveillance systems have embraced improved technology, such as encryption, leading to increased levels of security.

Shocknesse stressed the crucial role of cameras and onboard recording, stating that it is imperative to have them. The cameras are installed with memory devices, which guarantees that even if there are any problems, the footage of the incident is still being recorded and can be submitted to the police department.

Additionally, he stressed that the most efficient way to prevent cell-jamming is to use up-to-date technology with encryption and to opt for a wired device instead of Wi-Fi, as an addition to his previous recommendation.

When it comes to thwarting home break-ins, it is important to remember that simple precautions can go a long way. This includes maintaining sufficient lighting, activating alarm systems, and ensuring that bushes are trimmed to a maximum height of three feet.

 

 

In today's society, mobile phones have become an indispensable tool for individuals. However, their usage within conference rooms often poses serious challenges, such as interrupting the meeting's flow and distracting other participants. Hence, the implementation of a mobile phone signal jammer serves as an effective solution to ensure a smooth and uninterrupted meeting.

The implementation of cell phone signal jammers within the conference room proves to be highly effective in obstructing cell phone signals. This, in turn, ensures that mobile phones do not disrupt the smooth flow of meetings. By prohibiting the use of mobile phones, participants are able to fully engage in the meeting without any distractions. Moreover, this measure also serves as a protective measure, safeguarding the personal privacy of attendees and preventing any unauthorized access to sensitive meeting information.

Moreover, the mobile phone jammer exhibits a remarkable ability to shield signals and provide extensive coverage. Its range extends to cover the entirety of the conference room, ensuring that the meeting remains unaffected by external factors. Furthermore, its advanced technology ensures an outstanding signal shielding performance, guaranteeing that mobile phones do not interfere with the proceedings.

Moreover, cell phone gsm jammer boast a user-friendly nature. Their operation is simple and easily understandable, making them accessible to all users regardless of technical knowledge. By effortlessly installing the device in the conference room, it becomes instantly operational. Hence, the presence of specialized technicians is unnecessary for its operation.

The utilization of mobile phone signal jammers within conference rooms is limited to a particular range.

The mobile phone signal jammer, despite its moniker, does not impede the signal as a typical jammer would. Instead, it functions akin to a signal jammer.

The signal tower serves as the intermediary for the transmission between mobile phones, following the path of mobile phone-signal tower-mobile phone. However, when a signal jammer disrupts the connection path between the mobile phone and the signal tower, the transmission is impeded. It is important to note that the signal tower remains unaffected by this interference. As mobile phones are shared within a particular area, it is common to encounter situations where the normal usage of mobile phone signals is hindered, even outside of conference rooms.

It is important to understand that conference room cell phone signal jammers do not offer a complete solution.

Presently, cell phone signal jammers in the market can limit cell phone signals from a distance of 1640ft 5in meters from the transmitting station and a radius greater than 65ft 7in. The shielding radius is adaptable. It only obstructs mobile phone signals and does not influence other electronic devices. Hence, if you are encountering weak mobile phone signal even when you are not near the examination room, do not hold the signal jammer responsible. It might also be a problem with your own mobile phone.

Conference rooms are subject to regulations regarding the frequency bands that can be impacted by mobile phone signal jammers.

Electromagnetic waves cover a broad frequency band, ranging from a few Hz to tens of hundreds of GHz. While every segment can be utilized, certain segments are more frequently used than others.

1. The GSM receiving frequency band is 885~960MHz;


2. The receiving frequency band of CDMA is 869-894MHz;


3. The receiving frequency band of DCS is 1805-1880MHz.

According to arrest warrants obtained on Friday, a group of tech-savvy burglars who have been targeting homes in Connecticut and Massachusetts broke into a local residence. The burglars were able to gain access to the residence by obtaining detailed information on the security system from the homeowner's co-worker.

Arrested on allegations of conspiracy to commit first-degree burglary and conspiracy to commit second-degree larceny is Matthew Colon, aged 31, residing in West Springfield, Massachusetts. Similarly, Enrique Santiago, a 37-year-old individual from Springfield, Massachusetts, is confronted with charges that include first-degree burglary, possession of burglary tools, theft of a firearm, and conspiracy.

The warrant for Colon reveals that the police are likely to detain a third man involved in the case. This investigation is intertwined with a series of other burglaries, which were executed using advanced surveillance techniques and insider knowledge about homeowners' absence.

On May 20, 2022, a Long Island resident of Green Manor Terrace contacted the police, reporting that two men were seen walking through his backyard on a security camera. The officers who intervened in the burglary discovered a broken rear sliding glass door and a series of abandoned evidence near the property, such as a WiFi jammer, a two-way portable radio, a glass punch tool, a pry bar, and bolt cutters, as stated in the warrant.

As mentioned in the arrest warrant affidavit penned by Windsor Locks Detective Sgt. Jeff Lampson, the thieves were able to breach a chain link fence and disable surveillance cameras through both manual means and the use of a WiFi jammer. However, one camera located near the pool was not affected by the jammer device and remained operational, recording the incident. The homeowner reported the disappearance of US$4,200 in cash, along with men's watches, jewelry, and his wife's 9 mm pistol, according to the warrant.

The police have reported that on May 26, a pillowcase was uncovered by a resident living two houses away. Upon inspection, the pillowcase was found to contain watches, a handgun, and other items that were confirmed by the victims as their own. Following the break-in, the burglars fled in separate directions, as evidenced by the locations of the stolen bag of items and the backpack containing a wifi jammer.

According to Lampson's statement on Friday, the use or operation of gsm jammer devices is not allowed by federal law and federal investigators are looking into the matter. Furthermore, he pointed out that the local police have witnessed a surge in the use of these devices in residential burglaries.

However, in this case, the police were able to conclusively prove the undoing of the thieves through DNA evidence. While conducting a thorough search of the Green Manor Terrace area during daylight hours on May 23, a homeowner came across a pair of gloves that she had not previously seen and immediately turned them over to the investigators. The police then submitted swabs taken from the gloves, along with other potential evidence believed to have been touched by the thieves, to the state forensic laboratory for analysis.

Lampson's warrant stated that on August 16, the lab reported a DNA match on the gloves to Santiago, indicating the involvement of an offender. The police disclosed that the same DNA was linked to two prior burglary cases, one of which was a car break-in in Middletown from 2010, and the other was a burglary in South Hadley, Massachusetts in 2012, where firearms were stolen. Santiago was arrested in both instances, according to the warrant.

According to the warrant, Santiago relayed to the investigators from Windsor Locks, through his attorney, that the burglary at Green Manor Terrace was coordinated by a man driving a black sedan, whose father happened to own a remodeling company. Lampson, in the same warrant, documented that when he asked the homeowner if he was acquainted with an individual fitting that description, the homeowner promptly identified Colon, who worked alongside him at a home health care business in East Longmeadow, Mass.

According to the warrant, the homeowner expressed that he regarded Colon as a friend and had disclosed information about his visit to Long Island in May. The victim also mentioned that Colon and his father had aided him in remodeling his house. The warrant indicated that the homeowner stated that Matthew Colon had frequented his residence on numerous occasions and was fully aware of the surveillance camera system.

After being confronted with the victim's statements and the evidence pertaining to the burglary, Colon admitted to the police that he had been manipulated into becoming involved in the scheme by the third suspect. The warrant indicates that the authorities anticipate the imminent arrest of the third suspect.

The suspect's girlfriend was employed at the same home health care business as Colon and the victim from Windsor Locks. Lampson's warrant stated that other employees of the company had their homes in Massachusetts burglarized. One woman claimed that Colon had been at her residence to fix a gazebo before the break-in.

The warrant stated that cellphone records provided evidence of phone calls between Colon, Santiago, and the unidentified suspect both prior to and following the Windsor Locks burglary. The police have described the third suspect as a convicted felon with a significant criminal background, which includes armed robbery and a series of burglaries.

Santiago's extensive criminal record, as mentioned in the warrant, includes convictions for burglary and larceny in Connecticut. The Massachusetts investigators suspect his involvement in a criminal organization that specializes in targeted burglaries. Santiago has posted a bond of US$150,000 and is expected to make an appearance in the state Superior Court in Hartford on May 31. Similarly, Colon has posted a bond of US$100,000 and is scheduled to appear in court on May 2.

 

ASSERTION: A colossal, glowing skeleton was erected above passersby in an open square near the Burj Khalifa using drones as part of a Halloween exhibit.

The claim that the video is authentic is false. According to experts, there are clear indications that the "drone show" is a fake, such as its speed, which exceeds the current capabilities of drone technology. Furthermore, the audience below the skeleton does not respond to the massive spectacle above them signal jamming.

It has been widely circulated on social media since Halloween that a video showed a nighttime display that almost reached the height of the Burj Khalifa, the world's tallest building.

Within the brief 8-second video, a formation of illuminated drones creates the appearance of a skeleton. This drone skeleton gracefully moves forward, suspended directly above the pedestrians who are leisurely strolling around an open-air plaza adjacent to Dubai Mall, a renowned shopping destination. Notably, the skeleton's height almost mirrors the towering skyscraper, measuring an impressive 2,716 feet and 6 inches (828 meters) drone jammer.

One TikTok post that shared the video stated, "Dubai's #Halloween drone show takes a chilling twist as a haunting skeleton appears in the sky." As of Friday, the video had garnered around 8.5 million views.

Other individuals added a political twist to the alarming demonstration, such as a message on X, previously known as Twitter, that declares: "During Halloween, the UAE organizes a remarkable drone simulation featuring a colossal skeleton at Burj Khalifa in Dubai. This choice has provoked anger among numerous Muslim nations, who perceive Halloween as a 'satanic holiday' coinciding with the tragic occurrences in Gaza."

However, various specialists have informed The Associated Press that the video does not truly portray a structure constructed from drones.

Preston Ward, the chief pilot and general counsel for Sky Elements Drone Shows in Fort Worth, Texas, confidently stated that the display was completely fabricated. He not only exposed the falsehood on social media but also emphasized its fraudulent nature.

Ward highlighted several indications in the video suggesting that the skeleton is not as it appears. Firstly, it exhibits an excessive speed that surpasses the capabilities of current drone technology. Additionally, the estimated 2,000 drones involved in the display emit an unexpectedly low level of noise. Lastly, there is an improbable flawlessness in the overall presentation.

He expressed, "The appearance seems excessively flawless, as well. There will always be some room for error. In a live performance, there will always be some element of unpredictability. Moreover, all their hues appear identical, and the illuminations possess an identical radiance."

Furthermore, Ryan Sigmon, co-founder of Firefly Drone Shows in Detroit, concurs that operating drones above pedestrians in a densely populated vicinity, as depicted in the video, poses a significant safety risk. He also acknowledges that the skeleton portrayed in the footage lacks authenticity.

Apart from the technological and logistical considerations, there seems to be a lack of reaction from anyone in the video towards the massive structure hovering above them. It is quite unusual that this is the only video available online from the supposed show, especially considering the prevalence of smartphones in today's age. Furthermore, there have been no announcements or advertisements regarding any such show taking place in Dubai.

The origin of the video remains unknown, but it was shared on TikTok by Geoscan Group, a drone show production company, on Tuesday and garnered millions of views. Despite being contacted for comment, Geoscan has not responded, and the video has since been removed from their TikTok account as of Friday.

To gain further insights into AP's fact-checking initiatives, please explore additional information on fact-checking at AP.

According to an official statement, a US Reaper drone was downed by Houthi rebels backed by Iran in the vicinity of Yemen.

According to a defense official, Houthi forces have successfully shot down an unmanned US military drone near the Yemeni coast. This incident was reported by CNN.

According to the official, the MQ-9 Reaper drone was operating in international airspace and over international waters at the time it was shot down. The incident is currently being investigated by US Central Command.

The shootdown, for which the Iran-backed Houthi militants assumed responsibility on Wednesday, took place a few weeks after the USS Carney, a US Navy warship, intercepted a series of missiles and drones fired by the Houthis as they were moving northward along the Red Sea. As reported by CNN, the ship successfully neutralized four cruise missiles and 15 drones within a nine-hour timeframe. The clear trajectory of these weapons left little room for speculation regarding their destination, which was evidently Israel.

In the wake of Hamas' assault on Israel, Iranian proxy factions have intensified their assaults on US forces and properties in the Middle East. Over the past few weeks, there have been approximately 40 attacks on US and coalition bases in Iraq and Syria, resulting in minor injuries including traumatic brain injuries among several US servicemembers, as confirmed by officials.

The attacks on US forces in the region have been attributed to Iran by a senior defense official who referred to the country as "the center of gravity". The official also stated that the evidence points to Iranian involvement in the attacks.

On October 26, the United States responded to the actions of certain groups by conducting airstrikes in Syria. The airstrikes specifically targeted the infrastructure that was being utilized by the Islamic Revolutionary Guard Corps and its associated groups. To carry out these strikes, an F-15 fighter jet and a pair of F-16 fighter jets were deployed, employing precision-guided munitions. The primary objective was to neutralize a weapons and ammunition storage facility located in Abu Kamal, which is situated near the border separating Syria and Iraq.

CNN has informed that Iran is aiming to take advantage of the negative response towards the US backing of Israel. Although Tehran may not be directly instructing the groups' assaults, it does seem to be promoting them.

After the retaliatory strikes in Syria last month, the US Defense Secretary Lloyd Austin delivered a stern caution to Tehran.

The statement released by Austin suggests that Iran may be involved in the recent attacks against our forces. However, we believe in maintaining open channels of communication with all nations and will continue to engage in dialogue with Iran to address any concerns. We remain committed to protecting our forces and will take necessary measures to ensure their safety.

 

Referred to as a bombing drone, this unmanned aerial vehicle (UAV) is specifically engineered to execute drone strikes. It is categorized under combat drones, which encompass a range of functions including target acquisition, surveillance, reconnaissance, and intelligence gathering.

Even though bomber drones lack human presence, they are not entirely automated. Rather, they are usually controlled by humans in real-time from a distant location.

Clearly, there is a substantial decrease in weight when compared to regular aircraft, as the presence of a human pilot and their associated needs are completely irrelevant in this scenario.

Here is a succinct examination of stealth bombers and the intricacies involved in neutralizing these military aircraft.

Debunking the Myth of Detecting Stealth Bomber Drones.

In an ideal scenario, bomber drones would exemplify the true essence of stealth. As one can envision, this implies evading detection from targets completely. Any potential compromise could lead to an unsuccessful conclusion of an ongoing mission.

The US Air Force's RQ-170 is a notable example of a compromise. In December 2011, an RQ-170 crashed on the Iran-Afghanistan border, and the Iranians promptly retrieved the debris to start developing their own version of the technology.

The RQ-180's creation is attributed not just to the capacity to duplicate but also to the aptitude to refine the initial blueprint. These unmanned aerial vehicles are meant to be covert surveillance drones, but what does the concept of "stealth" entail in this scenario?

When it comes to drone stealth, many individuals primarily consider its capability to elude radar detection. Although satellites possess comprehensive visibility, their inflexible operational nature restricts adaptability, thereby contributing to the integration of detection avoidance mechanisms in specific designs.

Radar technology operates in a straightforward manner. It sends out a signal that reflects off an aircraft, revealing its position and allowing for tracking capabilities.

Nonetheless, the complexity escalates when it comes to drones that have a reduced size, thus giving rise to the notion of their ability to remain undetected.

The problem with this misconception is that it overlooks the significance of radio frequencies. Undeniably, achieving autonomous control requires a certain level of communication based on frequencies. However, it is important to note that these frequencies can be disrupted using the appropriate technology.

Nonetheless, pursuing this method does pose a greater challenge as opposed to solely utilizing radar identification to detect drones.

In order to render a bombing drone inoperable, what items would be necessary?

Under the classification of equipment here, there are two distinct categories: drone detection and drone disruption. The former is concerned with the identification of drones, while the latter concentrates on disabling the detected drones.

The Leading Four Technologies for Countering Unmanned Aerial Systems.

Drones have the potential to jeopardize human health and safety, as well as security. Furthermore, they are frequently utilized for spying and obtaining delicate information from protected areas, such as military bases, and can cause harm by transporting explosives.

The counter-drone technology sector has been making great strides, especially in the military arena. To discover the four most sought-after counter UAS technologies, keep reading.

Webs

To apprehend drones, militaries often rely on this drone detection solution. When the net successfully captures a drone, it immediately immobilizes it, causing it to descend to the ground. This efficient method not only prevents the drone from returning to its sender but also safeguards against the risk of sensitive information being compromised or, even worse, the potential for physical damage resulting from any explosives it may be carrying.

The use of nets to capture drones has several benefits, such as a reduced likelihood of harm to the sender or innocent bystanders from explosions. Furthermore, the sender can be located and held accountable with the help of nets. The accuracy of ground-based net launchers is also noteworthy.

A disadvantage of using drone deployed nets is the considerable amount of time it takes to reload them. Consequently, if there are multiple drones or if the initial attempt fails to capture the target, the threat persists.

Radar

The utilization of radio energy enables radar to effectively locate objects. Thanks to radars, the precise direction and position of a drone can be measured. Most radars emit a radio signal and then analyze the resulting echo. However, they have limited capability in detecting small targets. Initially, radars were designed to track larger objects such as passenger aircraft. Nevertheless, military organizations also employ radars to locate smaller drones that may potentially be in the vicinity.

Benefits: Radars offer extensive coverage of large terrains and deliver accurate positioning data, enabling the simultaneous detection of multiple targets. In order to maintain a stringent defense posture regardless of adverse weather conditions, radars prove to be an optimal solution, even in scenarios characterized by poor visibility such as fog, nighttime, and others.

Disadvantage: Small drones and small flying animals like bats or birds are indistinguishable to most radars. This makes radars less efficient for military use, as they may fail to detect small drones.

High Power Microwave (HPM)

Drones are vulnerable to the disruptive effects of High Power Microwave devices. The HPM's electromagnetic waves can interfere with the radio signals that control a drone's movements, making it difficult or impossible to steer. Additionally, the high voltage and currents of the HPM can cause damage to the drone's electronic components, rendering it inoperable. This makes the HPM a valuable tool for neutralizing drones in situations where they pose a threat.

Benefits: Capable of effectively ceasing drones that are situated within the HPM coverage area.

While this technology offers protection to military bases and highly secured areas, it carries the risk of unintentionally damaging and even destroying other electronic devices. Furthermore, HPM can disrupt communication signals as well.

GPS Spoofer

This technology enables the transmission of a signal to the detected suspicious drone, effectively misleading it about its current location. Through the dynamic alerting of GPS coordinates, the spoofer gains control over the drone, facilitating its removal to a designated "safe zone." As a result, the presence of the drone is mitigated, reducing the associated risks.

Benefits: One of the major advantages of GPS spoofers is their affordability, making them accessible for armies to procure in larger quantities and utilize in multiple locations.

Disadvantage: Sadly, there is a downside of potentially disrupting other radio communication signals.

By analyzing the potential risks, the system operator concludes that electronic methods, particularly soft-kill tactics like frequency drone jamming, can effectively neutralize the UAV threat.

gps jamming refers to the targeted emission of concentrated RF power towards the frequency channels employed by the Drone for telemetric, control, and navigation functions. The effective range of the jamming signal, which is influenced by factors like line of sight and power output, can extend to around 5Km or even greater distances when utilizing high power output (>50W).

According to authorities, a devastating explosion took place at the Canadian border, resulting in the unfortunate deaths of two individuals. The incident occurred when a car, while airborne, crashed into a checkpoint at the Rainbow Bridge in Niagara Falls, New York, on Wednesday.

Numerous aspects of the incident at the Rainbow Bridge remained shrouded in uncertainty, causing apprehension on both sides of the border as the United States neared the Thanksgiving holiday. Subsequently, President Joe Biden and Canadian Prime Minister Justin Trudeau were expeditiously provided with comprehensive briefings. Trudeau, acknowledging the gravity of the situation, temporarily excused himself from the Question Period in the House of Commons to obtain further details, emphasizing the exceptional level of seriousness with which officials were addressing the matter.

As of now, there are no visible indications of terrorism, according to the statement made by Governor Kathy Hochul of New York to the press.

The speaker emphasized that there is currently no sign of a terrorist attack. It is crucial to restate that, at this moment, there is no indication of a terrorist-involved incident taking place at the Rainbow Bridge in Western New York.

The car accident claimed the lives of two individuals, with one of them identified as a resident of western New York.

Officials have stated that the car, which was traveling at a high speed, crashed, caught fire, and exploded on the U.S. side of the border. This contradicts earlier claims that it had originated from Canada.

According to Hochul, she has viewed a video capturing the car, which was moving at an "exceedingly high speed" before it took flight in an "incredibly surreal" scenario.

The sight of the "airborne" vehicle left Rickie Wilson, a Gray Line Tours staff member, in utter shock. He recounted that the car had seemingly hit a cement median before soaring into the air.

Wilson informed NBC affiliate WHEC of Rochester that initially, he mistook it for an airplane, as it appeared to be moving in slow motion. He exclaimed, "My goodness, it's a car! It's a vehicle! And it's soaring through the sky!"

His estimation indicated that the car was elevated approximately 10 to 15 feet above the ground.

Wilson informed the reporters about the perplexing situation, questioning the means by which the object had ascended to such heights. Expressing his astonishment, he emphasized that the object had been suspended in the air, clarifying that it was not merely a few feet above the ground, but significantly elevated.

As per a law enforcement official, a Customs and Border Protection employee experienced minor injuries and was subsequently provided medical care at a hospital. Hochul emphasized that the employee was stationed in the booth, which acted as a literal shield, ensuring the individual's safety.

According to Hochul, the vehicle has been completely incinerated, with only the engine remaining. The fragments of the vehicle are now spread out across approximately 13 to 14 booths.

Explosion near Niagara Falls

The authorities have reported that a preliminary search did not reveal the presence of any secondary explosive or device. It is important to keep in mind that this information is subject to change.

The authorities are currently conducting an investigation to determine if the crash was deliberate.

Hochul conveyed in a news briefing that the event was a "dreadful mishap" that resulted in heightened anxiety across western New York, Albany, and Washington.

This event unfolded on a day known for its high travel volume in the United States, as countless individuals embarked on their Thanksgiving holiday trips, making it one of the busiest days of the year.

Devices called bomb signal jammers are capable of broadcasting a signal on certain radio frequencies, which causes interference with other radio transmissions on those frequencies. The main objective of bomb jammers is to thwart the detonation of radio-activated bombs, also known as radio-controlled improvised explosive devices (RCIEDs).

Terrorists have long used cellular phones to trigger improvised explosive devices (IEDs) in their attacks throughout the world. Although the time lapse between the activation of the cell-phone trigger and the explosion detonation has been only seconds in some bombings, one London terrorist bomb took nearly an hour to detonate after the initial attacks. This extended time lapse between triggering and detonation indicates that cell-phone signal jamming equipment could be used to prevent cell-phone detonation of explosives. A jamming device blocks the cellular downlink frequencies, preventing a cell phone's ability to receive an incoming call (uplink capabilities still function); however, it cannot prevent a cell phone's alarm function from detonating a bomb. One expert estimates that jamming equipment can obstruct half of all cell-phone bombs, along with remotely controlled bombs that use other remote instruments, such as garage door openers or toys. Separate equipment exists that can prevent bombs that use the cell-phone alarm function. U.S. Federal law currently allows only Federal law enforcement agents to use such jamming equipment. Because of delayed Federal response to bomb discoveries at the local level, many local police agencies favor being allowed to purchase and use jamming equipment. The Cellular Telecommunications & Internet Association is currently working with the U.S. Department of Homeland Security to develop a protocol that will retain Federal authority for determining when and how jamming equipment will be used, while allowing for a Federal directive that allows a specific use of jamming equipment by local police.

Bomb Jammers

The interruption of enemy communications to bombs and RCIEDs is effectively achieved through the use of bomb phone jammer, which transmit radio signals on the most commonly utilized frequencies by such devices. This strategic approach holds immense importance in various tactical scenarios, especially in thwarting the remote detonation of roadside bombs. Bomb gsm jammer are extensively deployed in public areas, SWAT scenarios, and vehicles to provide mobile convoy protection.

Bomb Jamming

Bomb jamming assumes a pivotal role in multiple situations, serving as a fundamental tool for law enforcement, military operations, VIP protection, and counter-terrorism applications.

 

A new drone has been introduced by Ukraine, claiming its ability to conduct missions in enemy-controlled areas with remarkable efficiency. Notably, this drone has been specifically engineered to counteract Russian attempts to disrupt its communication signals.

Ukraine claims that the Backfire is equipped with a GPS antenna for navigation purposes and has a range of 20 miles.

The dominance of UAVs in modern warfare has spurred Ukraine and Russia to make notable progress in their drone technology.

 

The latest drone introduced by Ukraine has the remarkable ability to traverse extensive distances beyond enemy borders while effectively countering ongoing Russian attempts to disrupt its operations.

Constant technological advancements and the omnipresence of drones on the battlefield and in the airspace have fueled the ongoing drone war between Russia and Ukraine, marking the latest development in this conflict.

The Backfire unmanned aerial vehicle (UAV) was introduced by Mykhailo Fedorov, the Vice Prime Minister of Ukraine for Innovation, Education, Science, and Technology, on Monday. Fedorov referred to it as a "formidable drone" that can fly up to 20 miles and cause "tremendous losses" to the enemy's rear positions.

Ukrainska Pravda reported that Federov mentioned the drone's ability to aid Ukrainian forces in striking Russian artillery, logistics hubs, enemy storage points, and command posts.

According to Fedorov's statement on X, the social networking site formerly referred to as Twitter, the Backfire's key characteristic is its "highly effective GPS antenna, resilient against Russian interference" and electronic warfare. Ukrainska Pravda conveyed that Fedorov also emphasized that this antenna is "nearly impervious to disruption," and thanks to the drone's "complete autonomy, the Russians cannot trace its coordinates and ground crew."

Ukraine's Backfire drone is on the verge of being mass produced and will soon join the country's array of UAVs in combat. Fedorov revealed that it has already completed more than 50 successful missions in the recent months.

Ukraine's latest contribution to the ongoing drone warfare is the Backfire, a development that has kept both sides on high alert due to the constant need for innovation driven by technological advancements. In combat scenarios, troops have increasingly relied on drones, with one Ukrainian service member disclosing in September that his unit had barely used rifles in the past six months, instead heavily relying on drones for their fighting capabilities.

Amidst the ongoing conflict, cost-effective UAVs have proven to be highly efficient in eliminating tanks and armored vehicles, which are primarily asymmetrical targets, as well as any mobile entity encountered on the battlefield. Regularly documented videos from the war exhibit first-person view (FPV) drones engaging in collisions with tanks, penetrating open hatches in armored vehicles, discreetly approaching troops in trenches, and causing explosions upon impact.

The continuous hum from above acts as a constant warning of the lurking danger, signifying that an unassuming target may fall victim to a sudden attack by an exploding UAV. Both Ukraine and Russia are actively involved in a race to acquire superior drone capabilities, driving them to pursue innovative technologies in order to gain an advantage over their adversary.

The significance of operators cannot be overlooked in the progress of Ukraine and Russia's specific flight and control abilities, in addition to the advancements in autonomous drones. Nevertheless, their importance also exposes them to enemy threats, leading to operators engaging in drone-based conflicts.

Efforts to counter the growing impact of drones have intensified over time. The front lines are now equipped with advanced jamming signal technology that disrupts the navigation controls of drones. While drones controlled by operators are usually less susceptible to such interference and are more affordable if lost or destroyed in battle, gps jamming still poses a significant obstacle. This underscores the vital importance of Ukraine's new Backfire system in blocking Russian interference, granting Ukraine the upper hand to maneuver along and behind enemy lines.

The defendant, Trenton Lisak, from Mobile, has pleaded not guilty to charges of obstructing public safety communication and drug possession on June 15, 2023.

According to the allegations made by prosecutors, he employed expensive and extremely advanced equipment from an apartment situated at the Tower on Ryan Park. Mobile County 911 officials assert that this action essentially halted communications in downtown Mobile on June 6 and caused disruptions for the following week.

The judge has set Lisak's preliminary hearing to take place on July 19th.

ORIGINAL STORY:

Expensive and advanced black market jamming device caused disruptions in police and emergency services transmissions for a considerable amount of time last week, as per law enforcement authorities.

On Saturday, Trenton Edward Lisak was taken into custody by law enforcement for impeding public safety communication, a serious offense that falls under Class C felony and can result in imprisonment for up to ten years. Furthermore, he is facing a drug charge. Prosecutors have revealed that the FBI is also looking into the case.

On Monday, Mobile County District Attorney Keith Blackwood remarked that the charge in question is out of the ordinary. He stressed the gravity of the situation, emphasizing the crucial need for law enforcement and first responders to have seamless communication abilities, regardless of their location, not just limited to downtown areas.

How out of the ordinary!

According to Blackwood, this was an entirely new experience for him. He couldn't remember encountering a similar situation before, especially not to this degree. The substantial quantity of equipment involved made it an exceptionally remarkable occurrence.

Lisak's arrest record discloses multiple charges, such as theft, breaking into cars, possession of a forged instrument, and engaging in criminal mischief.

Mobile County District Judge Jennifer Wright has established a bail amount of $15,000, which aligns with the highest recommended bail for this particular offense. Furthermore, she has mandated that 10 percent of the bail be paid in cash. Additionally, Judge Wright has imposed an extra $5,000 bail specifically for the drug charge.

Moreover, the judge established a curfew spanning from 8 p.m. until 8 a.m. and mandated that Lisak, who is 31 years old, refrain from approaching the Tower at Ryan Park situated in downtown. This particular apartment complex is where authorities uncovered the equipment responsible for interfering with the communication networks of all 57 law enforcement, fire, and emergency medical agencies associated with the Mobile County Communications District.

Lisak's booking information indicates that the aforementioned address is his place of residence. Nevertheless, the prosecutor informed the judge that investigators have reservations about whether he was truly residing there.

Robert Jackson, a district administrator, characterized it as "an exceptionally advanced apparatus arranged within the apartment, specifically engineered to disrupt our signal."

Jackson added, "In order to locate it, we had to make adjustments to our instruments."

FOX10 News was informed by Charlie McNichol, the director of the 911 system, that the interference caused a complete halt in communications for a full day last week.

Last week, on Tuesday, it brought about notable complications in the downtown region," he remarked. "Specifically, our tower site located at Government Plaza was the origin of the alarm signals. As a result, the first responders encountered significant challenges in their communication endeavors."

It remains unclear what the motive may have been, officials said. Blackwood said he does not know what the defendant was planning, or where he got the equipment.

McNichol said he does not know if Lisak just enjoys watching chaos or if he had something more sinister planned and attempted to jam communications as part of that.

"This individual had some gps jamming equipment that you buy on the black market," he said. "It's illegal to even possess it. And that's what was causing the problems."

Across various domains of application, the United States is witnessing a rapid increase in the daily deployment of drones. These unmanned aerial vehicles are being utilized for tasks ranging from inspecting infrastructure to delivering packages. While the Federal Aviation Administration (FAA) regulates the airspace, it is imperative for cities to familiarize themselves with the burgeoning industry that will ultimately operate within their communities. This understanding will enable them to effectively capitalize on the benefits for their residents while also safeguarding against any potential challenges that may arise.

The Significance of Cities in America's Expanding Drone Industry

The potential benefits of drones for American cities are becoming increasingly evident, with their large-scale deployment expected to have a positive impact on society, from the environment to the economy. Many cities are already experiencing a rise in drone usage for a variety of applications, such as public safety, medical deliveries, retail package delivery, and infrastructure inspection. By expediting the implementation and advancement of drone jammer infrastructure, cities can modernize more quickly while also complementing and easing the burden on conventional infrastructure as this emerging technology takes to the skies.

The report by NLC sheds light on the significance of cities in the development of drones. It suggests that city governments can still exercise some control over drones despite the FAA's final rule. Rather than imposing a blanket ban, officials should explore ways to leverage this technology for the benefit of residents and city services.

 

Through partnerships with federal, state, and local governments, drone signal jammers operators, and industry leaders, Airspace Link has created a framework for cities to engage in the drone economy, with a focus on resident safety and security and community value.

Delving into the Extended Value, Through Statistical Analysis.

The ambitious vision of drones contributing to economic, environmental, and societal progress can only be fully achieved when operations are scaled up comprehensively. In order to facilitate the widespread use of drones, it is crucial for all stakeholders, including cities, to demonstrate their commitment towards establishing the required infrastructure and regulations.

Shield Your Personal Space from Drone Intrusion and Surveillance.

Drones have the potential to infringe upon people's privacy by invading their personal space and collecting personal data without their consent, which can inadvertently expose their privacy. Furthermore, the continuous recording of video footage during flight can lead to the collection of information about random citizens without any legitimate purpose, which can be a violation of their privacy.

Anti-regime factions are employing unmanned aerial vehicles on a larger scale to launch attacks against military personnel.

According to reports from rebel groups and drone operation groups, resistance fighters in Myanmar have started to heavily depend on drones for launching attacks against the country's military forces. This change in tactics has become possible after successfully bypassing the junta's anti-drone jammers, enabling them to exploit this advanced technology in their struggle against oppression.

According to Ko Nyein, who heads the rebel drone unit Cloud Wings in Kayin state, eastern Myanmar, the drones' performance has undergone a significant improvement.

According to his statement, their drones have been enhanced to carry heavier payloads, operate at higher altitudes and cover longer distances, while successfully bypassing the interference caused by the junta's signal jammers. Additionally, he highlighted the expanded utilization of their drones across multiple military units in Myanmar.

According to reports from three drone forces operating in Kayin and Kayah states, as well as Sagaing and Magway regions, rebel forces executed around 642 drone attacks on junta soldiers in 2022.

According to militia groups affiliated with the National Unity Government, there has been a rise in the utilization of drones this year. Unfortunately, due to security concerns and the sensitivity surrounding their military operations, they were unable to disclose any specific information.

The groups have not provided any data on the number of drone attacks that have occurred this year, as of yet.

 

According to drone operators, the People's Defense Forces (PDFs) and ethnic militias have resorted to contemporary warfare technology in their fight against the military forces that took control after the 2021 coup. These groups, consisting of ordinary citizens, have encountered junta soldiers equipped with machine guns and anti-drone defense systems at crucial military installations. As a result, the PDFs and ethnic militias have turned to the use of drones to counter these challenges.

In the beginning, the rebel fighters placed their trust in makeshift weaponry, encompassing tumees, hunting rifles, launchers, and bombs, as their means of resistance against the armed forces of the nation.

PDF personnel have reported an escalation in the deployment of attack drones equipped with bomb-dropping capabilities, following the successful neutralization of the junta's anti-drone defense system.

The National Unity Government's shadow administration, consisting of ex-civilian leaders and anti-junta activists, has reportedly supplied more than 400 attack drones to loosely regulated militia factions, as per Maung Maung Swe, the deputy secretary of the Ministry of Defense.

Our understanding of the junta's drones' capabilities and limitations is comprehensive, and we can now disable them with ease, as per the statement given to RFA. Our ability to penetrate their wifi jammers across the nation has been significantly enhanced by our knowledge of their frequency.

Cost of bombs

Over 100 anti-junta drone operations have been executed by the Cloud Wings drone force, which was established in Kayin state in March, as stated by Ko Nyein.

According to Ko Nyein, the considerable price tag of the diverse bombs installed on the drones has presented a formidable challenge.

The cost of the bombs, he mentioned, stands as the central obstacle we confront.

Over the course of September 1 and 2, the Cloud Wings drone unit carried out two attacks on the police station and municipal hall in Kyainseigyi city. These targeted strikes involved the deployment of 107-mm bombs.

On the subsequent day, the police station situated in Myawaddy city of Kayin region fell victim to an assault orchestrated by the Federal Wings, an alternative resistance group utilizing drones to strike against the junta's military forces and infrastructure. Tragically, this attack claimed the lives of five individuals, including the district administrator of Myawaddy and the acting commander of the junta's Light Infantry Regiment No. 175. Furthermore, an unspecified number of people suffered injuries as a result of this incident.

The junta is facing a significant threat from these drone attacks, as highlighted by Capt. Kaung Thu Win, a participant in the nationwide Civil Disobedience Movement.

According to the speaker, military forces used to be afraid of landmine attacks during their deployments in the past. But now, the most dreaded weapons for them are drones, which can be employed for defensive as well as surprise attacks, regardless of the time of day.

In addition, he mentioned that the military troops suffered significant damage from the bombs deployed by our drones, but it is important to note that these bombs are unable to completely eradicate an entire enemy unit.

Attack from a distance

Kaung Thu Win has stated that the Drone Guard, the anti-drone equipment utilized by the junta, has limitations and a significant number of soldiers stationed at bases lack the necessary skills to operate it.

On Sept. 11, junta troops stationed near Nat Yay Kan village in Chaung-U township, Sagaing region, faced an assault from fixed-wing drones operated by the Civilian Defense and Security Organization of Myaung. Remarkably, these drones were able to overcome the military jammers, which are intended to block radio signals and impede drone control.

 

 

To combat the escalating risk of drone strikes from extremist factions such as Hamas and Hezbollah, the Israeli Defense Forces (IDF) have taken proactive steps. Recent updates suggest that the IDF has significantly augmented the deployment of GPS jamming technology across the region.

Drones, also referred to as unmanned aerial vehicles (UAVs), have emerged as a preferred choice of weaponry for militant groups operating in the Middle East. Their exceptional maneuverability and precise targeting capabilities have made them a significant threat. To counter this, the IDF has made a strategic decision to increase the use of gps jamming. This measure aims to disrupt the guidance systems of these drones, rendering them ineffective.

GPS jamming refers to the transmission of radio signals that interfere with the GPS reception of drones, leading to the impairment of their navigational capabilities. By disrupting the GPS signals of these drones, the IDF aims to counter their threat and mitigate the risk of potential attacks on Israeli soil.

Utilizing drones for surveillance and offensive operations against Israel, Hamas and Hezbollah, both recognized as terrorist organizations by multiple countries, have become a significant concern. In response to the threat posed by these drone attacks, the IDF has taken measures to enhance its countermeasures.

 

The IDF's utilization of GPS jamming technology highlights the escalating arms race between militants and national defense forces. With the rapid advancements in drone technology, military organizations worldwide are proactively investing in countermeasures to combat this emerging threat and mitigate potential risks.

It should be highlighted that GPS jamming serves as a defensive measure employed by the IDF to ensure the safety of both civilians and national security. While this action may temporarily disrupt the functioning of legitimate civilian GPS jamming device nearby, it is necessary to counter the potential risks associated with drone blocker attacks.

The IDF's heightened attention to GPS jamming is a clear indication of the ever-changing landscape of 21st-century warfare. As extremist groups continue to leverage technological advancements, defense forces must remain vigilant and adapt their strategies to ensure national security.

 

 

The prospect of fashioning a DIY drone jammer may seem formidable, much like the endeavor of constructing a DIY drone. Nevertheless, the truth is that fabricating a DIY drone jammer is significantly less complex than assembling a DIY drone. Within this comprehensive guide, we will outline the entire process of producing a drone jammer and resolving any troubleshooting concerns.

Could you provide a definition for a drone jammer?

The purpose of drone jammers is to ensure the safety of users and their operational zones by countering drone jamming. This involves utilizing a range of telecommunications hardware that possesses the capability to detect, receive, and interfere with drone signals. By integrating supplementary drone receivers and transmitters, customers have the ability to expand the system to an unlimited number of drones concurrently.

The capability of a drone jammer relies on its ability to disrupt signals within the drone jamming frequency range and the strength of its jamming power. Signal jammers, including cell phone jammer, WiFi jammers, GPS jammers, GSM/3G jammers, and drone jammers, are tailored to interfere with specific frequency bands.

 

A comprehensive tutorial on constructing a drone jammer with step-by-step instructions

To effectively block drone signals, it is essential to be aware of the radio bands utilized by potential drone threats. The commonly used drone radio frequencies encompass 433Mhz, 900Mhz, 2.4Ghz, 5.2Ghz, and 5.8Ghz. Determine the signal transmitter that aligns with the drone jamming band you deem most important.

The process of building a drone jammer requires the procurement of specific materials such as an RF generator, signal amplifier, power supply components, connection components, and a solid shell protection box.

To produce drone jammers, one must possess adequate hands-on proficiency and assembly skills, as well as a thorough understanding of signal jamming devices.

Once the drone jammer has been assembled, it becomes essential to evaluate its effectiveness in interfering with drones and determine the range of its interference. However, it is important to refrain from conducting these tests in densely populated urban areas to prevent any disruption to the surrounding communication systems.

The responsible application of drone jammers is a crucial aspect to consider：

Responsible utilization of drone jammer is paramount in order to prevent any potential harm to individuals or property. Here are a set of recommendations to bear in mind when using these devices:

The use of drone jammers should be reserved for critical circumstances, such as preventing drones from flying over restricted zones or engaging in illicit surveillance activities.

One must be mindful of the potential aftermaths that may arise from the usage of drone jammers. Tampering with radio waves can lead to harm to people and possessions, and disrupt significant radio signals, such as those employed by emergency services.

Prioritize understanding the laws and regulations governing the utilization of drone jammers in your region. Unauthorized use of drone jammers is prohibited in many countries. By employing drone jammers responsibly, you can effectively mitigate the potential risks associated with drone usage without causing harm to others.

Should you have a preference for off-the-shelf drone jammers over DIY alternatives, we suggest considering the Skyfend AFA100 Drone Jammer as a viable option.

 

DOD looking to buy a batch of counter-drone weapons for international partners

U.S. Army Aviation and Missile Command is conducting market research ahead of an anticipated purchase of up to 100 handheld drone jammers.

US Army Looking for Anti-Drone Signal Jammers Solution

 

The U.S. Army's Aviation and Missile Command is seeking potential sources of portable drone anti-tracking jammer that can interfere with control, video and navigation signals within a range of at least 5 km.

DefenseScoop has revealed that the Department of Defense is supplying air defense technology to Ukraine and Israel, while the AMC's Integrated Fires Rapid Capabilities Office-International plans to deliver a maximum of 100 handheld SkyWiper EDM4S devices to undisclosed U.S. allies.

Additionally, the device must have a minimum of six radio frequency modules, which should include 2.4GHz, 2xGNSS 1.5GHz and 1.2GHz, and 5.8GHz, as well as two custom frequency modules that cannot be altered by users. The Army has also mandated the use of high-gain directional antennas for accuracy and efficiency, along with a sturdy frame.

NT Service UAB of Lithuania is presently manufacturing the EDM4S Skywiper systems, which are marketed as an efficient anti-drone solution that can be operated by a single individual with ease.

The move is a direct response to the escalating use of unmanned aerial systems in various battlefields around the world, posing a threat to both U.S. military forces and their international partners.

 

 

The utilization of satellite signals extends beyond the mere provision of information to your vehicle's navigation system. GPS has evolved into an imperceptible yet indispensable resource that we depend on. Mobile phone jammer companies rely on GPS time signals to synchronize communication between your phone and their towers. Energy providers utilize GPS for harmonizing electricity grids during interconnections. Additionally, banks and stock exchanges employ satellite-based time-stamps to safeguard against fraudulent activities.

In the meantime, a neglected navigation system that has the potential to surpass GPS.

 

The security of Satnav, which controls a wide range of systems from power grids to air traffic control, is highly vulnerable. However, there is a more affordable and often ignored alternative that is ready to take its place.

Logan Scott believed it was 28 September 2022 and he was present at a conference centre in Portland, Oregon. However, the majority of smartphones in his vicinity were indicating a location in Europe, causing confusion. Some devices were even displaying January 2023 and declining to send messages or emails.

The conference centered around global navigation, and the issues arose when Scott was delivering a presentation on the vulnerability of GPS receivers to deception. To investigate, he borrowed a detector and successfully traced the origin of the problem. It was discovered that the GPS signal generator, intended for testing purposes, had not been adequately secured with terminal caps.

The error was swiftly rectified, however, a deliberate assault could potentially cause significantly greater damage. Originally designed by the US military jammer for defense purposes, GPS is now utilized in a wide range of applications, including power grids, financial trading, ambulances, and air traffic control. In order to mitigate the risks associated with relying solely on gps blocker, the European Union is constructing its own satellite navigation system, Galileo, which has become a contentious issue in the UK's negotiations to exit the union. Nevertheless, relying on additional satellites to support existing ones may not be the most optimal solution. Instead, a more practical technology, rooted in the second world war, could be reintroduced for our defense purposes.

The convenience of satnav has become ingrained in our daily lives. With just a simple pull out of your phone, you can instantly obtain your precise position within seconds.

With their expertise in hacking, they can aid you in bypassing security systems and keeping your identity concealed during the heist. Don't forget to prepare by stocking up on ammunition and selecting your preferred vehicle before embarking on your mission to locate the signal jammer units.

Grand Theft Auto 5's vast open world is filled with many collectibles and points of interest for players to discover. Among them are 50 signal jammers that can be found scattered across the city of Los Santos and Blaine County. Destroying these devices can grant players special rewards, but locating them can be tricky. In this article, we will cover everything you need to know about hunting down signal jammers in GTA Online.

What Are Signal Jammers in GTA 5 Online?

Signal jammers in GTA Online are small electronic devices that can disrupt phone signals and block internet access. They appear as small black boxes with blinking green lights, usually found attached to the side of buildings or on rooftops.

When nearby a signal jammer, players will be unable to use their in-game cell phone to access contacts, emails, web browser and other features. The phone signal strength indicator in the top right corner will show zero bars and display "NO SIGNAL."

Destroying signal jammers is beneficial because they negatively impact the GTA Online game world. With the gps blocker active, players cannot rely on their phones for communication and access to information. Shutting the jammers down restores full phone functionality and internet connectivity across Los Santos.

Locations of All 50 Signal Jammers

The 50 signal jammers are spread far and wide across the massive map of GTA 5, from downtown Los Santos all the way to rural Blaine County. Their exact positions are fixed but accessing them can require some climbing, flying or other creative approaches.

Some useful spots to check for jammers include rooftops of skyscrapers, sides of office buildings, atop construction cranes, water towers, radio masts, cell phone towers, and remote high spots in the countryside. Referring to interactive maps available online can make locating the jammers much easier.

 

Have you ever been defeated by a hidden gps tracker defense?

Just like your important personal information has been stolen by some criminals, you will face damage to your reputation and at the same time, you will also face the loss of wealth. Some Chicken Soup for the Soul will teach us to calm down Facing all kinds of failures.

When a car uses GPS or GNSS for positioning, it needs to receive multiple satellite signals at the same time to ensure accurate positioning. Therefore, we can see that when the car drives into a tunnel, etc., there is obstruction

In the environment, the GPS or GNSS positioning accuracy will be reduced to varying degrees or even completely lost.

Dead Reckoning DR is often used to compensate for GPS or GNSS positioning difficulties. When satellite positioning accuracy is reduced, Dead Reckoning calculates the position of the car by using information from various sensors (gyro sensors, accelerometers, speed pulses, etc.) Current location to maintain the car's positioning accuracy.

Precise positioning without online dead reckoning Dead reckoning most commonly uses an IMU to calculate the vehicle's real-time heading. Using this information, plus the distance traveled, the navigation system can correctly determine the vehicle's position. Dead reckoning ADR in high-end cars combines GNSS data with position information collected from relevant sensors installed on the body and wheels, and then performs positioning estimation. This most accurate positioning requires the vehicle's own data network integration to be sufficiently high.

In this modern society, with the rapid development of science and technology, we will face various problems. Maybe some small details can ruin your career. There is no doubt that protecting your privacy is important. Society teaches us to face failure in the right way, and also teaches us to avoid unnecessary failure in the right way. That's why we need GPS signal jammers, it's a great tool to protect our privacy.

Nowadays, almost every examination room will install an examination room signal jammer. However, this machine will become hot after being used for a period of time. The heat may affect the normal use of the machine. However, this is not certain. It's just that the heat dissipation capabilities vary depending on the brand. So, how does the signal jammer in the examination room dissipate heat? The old-fashioned signal jammer in the examination room could only rely on natural temperature to slowly cool down. But now, most examination room signal jammers are equipped with fans. Not only are these fans silent, but they also dissipate heat very well. It can help the instrument lower the temperature in time.

In addition, now schools are generally equipped with air conditioners. When the weather is too hot, the school will turn on the air conditioner or fan to ensure the safety of candidates. At this time, the temperature of the gsm signal jammer in the examination room will also drop. In fact, this thing is just like a mobile phone. In the summer, it will get hot as long as it is turned on. But it won't damage the machine. Especially for machines with better quality, you don't have to worry.

In real life, mobile phones have become an indispensable device in people's lives. However, using mobile phones in conference rooms often leads to serious problems, such as interfering with the progress of the meeting and affecting the attention of others. Therefore, using a mobile phone signal jammer is an effective solution to ensure that the meeting goes smoothly.

What should you pay attention to when using mobile phone signal jammer in a conference room?

Cell phone signal jammers can effectively block cell phone signals in the conference room to prevent cell phones from interfering with meetings. During the meeting, participants will not be able to use their mobile phones so that they can fully focus on the meeting. At the same time, this also helps protect the personal privacy of participants and prevent others from improperly obtaining meeting information.

Although the mobile phone signal jammer is called a jammer, it does not actually block the signal. Instead, it acts like a signal cellphone jammer.

Generally speaking, the connection between mobile phones will go through the signal tower, that is, the path of mobile phone-signal tower-mobile phone. The signal jammer will interfere with the connection path between the mobile phone and the signal tower, resulting in normal transmission. However, The signal tower is used by mobile phones within a certain range, so there are often situations where the mobile phone signal cannot be used normally even if you are not in the conference room.

Conference room cell phone signal jammers are not a panacea

Mobile phone signal jammers currently on the market can limit mobile phone signals that are 500M meters away from the transmitting station and have a radius of >20 meters. The shielding radius is adjustable. It only blocks mobile phone signals and does not affect other electronic devices. So if your mobile phone signal is not good recently when you are not near the examination room, don't blame the signal jammers. It may also be a problem with your own mobile phone.

 

The so-called signal shielding means that the receiving device cannot obtain a signal with a signal-to-noise ratio that meets the signal identification requirements. Signal to noise ratio (Signal Noise Ratio, SNR) is the most important content.

We can refer to the formula:

SNR = \frac{P_{Signal}}{P_{Noise}}

 

Therefore, there are two ideas for reducing the signal-to-noise ratio:

1. Reduce signal strength


2. Increase noise intensity

Based on the above ideas, we can use signal jammers to interfere/shield wireless signals.

The function of a signal jammer is to shield signals and is used in many situations. Nowadays, information spreads very fast. With a mobile device, all kinds of information can be spread to every corner in an instant. For some occasions where information cannot be spread, mobile phone signal cellphone jammer are very necessary.

Within a certain frequency range, mobile phones and base stations are connected through radio waves to complete data and sound transmission at a certain baud rate and modulation method;

Based on the above communication principle, the Dazhan jammer scans from the small-end frequency of the forward channel to the big-end at a certain speed during the working process. This scanning speed can cause garbled interference in the message signals received by the mobile phone. The mobile phone cannot detect normal data sent from the base station, making it impossible for the mobile phone to establish a connection with the base station. Communication equipment exhibits phenomena such as searching the network, no signal, and no service system.

Basic principles of 5G shielding:

Mobile phone signal jammers (jammers) achieve interference and shielding of wireless communication signals by emitting co-channel interference signals. The transmit power of the wifi signal jammer directly affects the strength of the interference signal, thereby indirectly affecting the shielding effect of the signal jammer. There is a positive correlation between these three. In other words, the stronger the transmission power, the stronger the interference signal, and the better the theoretical shielding effect in the same environment.

What factors affect the shielding effect? In the actual use environment, the interference signal emitted by the mobile phone signal jammer is affected by various factors, the most important of which are the following:

• The indoor jammer is recommended to be placed at a height of about 180cm-220cm above the ground, preferably at a forward angle.


• Is there any obstruction (such as walls, metal products, human body, etc.) between the gsm signal jammer and the wireless communication device (mobile phone, etc.). The interference signal emitted by the jammer will attenuate to varying degrees after passing through the obstruction, so please try to avoid it.


• The original wireless communication signal strength in the application environment of the jammer. The weaker the wireless communication signal strength in the use environment, the stronger the theoretical shielding effect of the jammer.


• The distance between the application environment of the jammer and the communication base station. The farther the application environment of the jammer is from the base station, the stronger the theoretical shielding effect of the jammer.

 

 

Mobile phone signal jammers are used in many places, but they cannot be used immediately after installation. We still need to go through certain testing and acceptance to determine its effectiveness and ensure its effectiveness.

It is very important to ensure whether the mobile phone signal jammers can truly effectively block mobile phone signals. When purchasing a mobile phone signal jammer, testing is a very important step.

1. Test the blocking distance of the mobile phone signal jammer. Don't just try it with one or two network mobile phones. The mobile phone networks used are different, especially the 4G mobile phone network. The 4G network uses a broadband high-speed transmission method. If the mobile phone If the signal cellphone jammer is not powerful enough, it may not be able to block 4G;


2. It is necessary to find all the mobile phones in the current network of mobile communication providers before testing. Make sure that each mobile phone network can meet the needs of at least one classroom to be considered successful. After turning on the phone to test the shielding effect, be sure to ensure that there is no signal on the mobile phone within half an hour and no time appears. sometimes not;


3. Another important point is that if it is a mobile phone wireless signal jammer with a metal shell, touch the front and rear sides of the fuselage with your hands after 1 hour after turning it on. If the temperature is moderate and not hot, there will be no problem. If it is very hot, it will not pass, because the machine continues to heat up. It will cause the power of the mask to attenuate, make it unable to work stably, and easily cause burns.

 

The main functions of the four major signal frequency bands used by drones

• 1. 2.4GHz frequency band


• The 2.4GHz frequency band is one of the more common frequency bands used in drones. It is a type of radio frequency band used by drones and is mainly used for WiFi and Bluetooth communications. This frequency band has a wider coverage and a faster transmission rate, so it is widely used in remote control and image transmission of drones.


• 2. 5.8GHz frequency band


• The 5.8GHz frequency band is one of the most common frequency bands in drones. It is also used in WiFi and Bluetooth communications, and is also widely used in drone image transmission systems. Compared with the 2.4GHz band, the transmission rate of 5.8GHz is faster, but the coverage range is relatively small.


• 3. GPS satellite signal frequency band-1.5G frequency band


• The GPS satellite signal frequency band is a type of frequency band used for drone positioning. It can accurately locate the position of the drone, thereby enabling flight path planning and tracking. GPS satellite signals are also one of the keys for UAVs to achieve autonomous flight and formation control.


• 4. Remote control signal frequency band-900 frequency band


• The remote control signal frequency band is a type of radio frequency band used for remote control of drones. It connects the drone flight controller to the remote controller to achieve remote control of the drone within a certain range. This frequency band has a smaller application range, but it plays an important role in remote control of drones.

 

 

In all types of examinations, it has long been a common practice to install wireless signal jammers in each examination room. However, almost 90% of examination centers choose low-power shielding equipment when selecting equipment. Why did you choose this? There are often high-performance shielding devices on the market, but why are they so common in exam rooms? What if you don't know how to use a high-performance signal jammer?

The answer to this question can be analyzed from two perspectives: one is the product performance and application scenarios of the powerful wireless signal jammer itself, and the other is the design of the examination room.

First, let's talk about the high-power wireless signal jammer. Its biggest feature is its high transmitting power and wide coverage. However, there are clear reminders in its instructions for use that high-power wireless signal cellphone jammer are mainly used in outdoor open environments. Environments like examination rooms are obviously indoor environments, and they are numerous and densely distributed. , each examination room is also separated by walls. This kind of wall barrier will shield the signal with great error, and it is easy to cause the shielded signal to only cover a local area or floor.

Considering these factors, high-power wireless signal jammers are strictly required not to be installed in buildings, but must be installed at an appropriate distance around a building. Moreover, for a building, at least 2-4 sets of high-power shielding equipment are usually required to basically meet the signal shielding needs.

The high-power wireless signal jammer itself also has the characteristics of large size, heavy weight, high heat dissipation and ventilation requirements, and high purchase cost. These characteristics also determine that high-power models are not suitable for the examination room.

Since high-power wireless gsm signal jammer are larger in appearance and heavier in weight, installation and construction are relatively complex, time-consuming and labor-intensive. Since the purchase cost of high-power wireless signal jammers is much higher than that of low-power shielding equipment, the price ratio between the two can reach 50:1 or even 100:1. We also take a building as an example. Suppose this building There are 50 examination rooms and classrooms in the building. If low-power wireless signal jammers are used, even if one is configured for each classroom, the total number will be 50. However, if you replace it with a high-power wireless signal shielding device, you may need at least 2-4 units. According to the aforementioned price ratio, you can conclude that if you use high-power shielding equipment, the construction investment cost may be Improved by 2-4 times.

 

Counter-UAS Non-Kinetic Soft-Kill Technologies

Non-kinetic counter-drones collect data by interfering with or intercepting transmission signals. These approaches typically result in the drone plummeting to the ground at high speeds, making it an unappealing countermeasure to deploy above crowds. While it may not be suitable for usage over crowds, it may be beneficial in other situations. When contemplating drone countermeasures, always consult your country's regulations; drone jammer and drone spoofers are not authorized in the United States.

What exactly is a drone jammer?

Jammers operate by emitting electromagnetic noise at the radio frequencies used by drones to operate and transmit data. They effectively drown out a drone's and its operator's talk. This is commonly 2.4GHz or 5.8GHz, which are unlicensed, public frequencies. This prohibits jammers from interfering with piloted airplanes, mobile phones, public broadcasting, or other radio frequencies that are not in use.

Jammers can be permanent, mounted devices or extremely mobile, gun-like devices that allow someone to safely land a drone on the ground.

What happens when a drone becomes jammed?

• The drone will either land or


• The drone will return to its starting point.

 

What are the drawbacks of drone jamming?

1. Drone jammers are less effective against pre-programmed drones that fly a certain course, because drones may fly without GPS.


2. Drone jammer prevent the C-UAS from gaining positive control over its targets.


3. UAV jammers do not detect the pilot or the flight route.

 

Is it legal to use drone jammers?

According to FCC regulations, drone jammers are not authorized in the United States.

"The use of "cell jammers" or similar devices designed to intentionally block, jam, or interfere with authorized radio communications (signal blockers, gps blocker, or text stoppers, for example) is illegal under federal law." These devices endanger crucial public safety communications and can prohibit you and others from dialing 9-1-1 or other emergency numbers. Law enforcement communications can also be disrupted buy jammers.

Governing Law

"The 1934 Communications Act"

• Section 301 - requires radio transmitter operators and users to be licensed or approved under the Commission's rules (47 U.S.C. 301).


• Section 333 - forbids deliberate or malicious interference with radio transmissions of any station licensed or permitted by the Act or operated by the United States Government (47 U.S.C. 333)"

 

 

What exactly is a GPS drone spoofer?

Spoofers send phony GPS signals that imitate authentic ones, whereas jammers function by blocking RF frequencies. Spoofers take over a drone's communication link by sending out a fake signal that the device interprets as authentic because it is a replica of the original signal.

The spoofer operates by sending out a stronger counterfeit signal. The spoofer can generate a slight delay between the drone and the controller before emitting the louder bogus signal. The spoofer now has complete control of the gadget and can fly the drone. The GPS receiver is duped by the spoofer.

If your UAS device uses GPS for flying, GPS spoofing is difficult to defend against. GPS is a signal transmitted by satellites. GPS satellite transmissions cannot be protected using traditional security methods such as encryption and certifications.

 

 

 

Deliveries of banned materials to prison inmates via drone are becoming increasingly ambitious and bold around the world, but an aerial smuggling ring busted by police in western France stands out for its quasi-startup organization and efficiency.

This summer, four gang members were arrested after Nantes police launched an investigation into the movement of contraband phones and drugs found during cell phone blocker searches. What they discovered was not only a well-organized and frequently used system for delivering prey using a DJI Mini, but also a Snapchat-based method of acknowledging commands from within Clink.

The perpetrators even gave their illegal company a name: Air Colis

Police became aware of the plan when guards first spotted a drone jammer hovering outside the window of a prison in Nantes. The next morning, authorities discovered 36 smartphones and 1.6 kilograms of drugs hidden by inmates. A month later, staff at another regional correctional facility spotted a drone making similar nighttime deliveries - an activity that was repeated at two other regional prisons around the same time.

Drone deliveries were often made to all four prisons on the same night, prompting local military police to cautiously begin investigations. They gradually discovered an operation (albeit illegal) that could teach the beleaguered Amazon Prime Air a lot.

This is how it functioned

Inmates monitoring contraband sales in their respective prisons placed orders with an outside partner, who in turn contacted four Air Colis organizers. The weight of each drone's payload (whether drugs, iPhones or tobacco) is limited to 500 grams, and transport costs a flat rate of 400 euros ($422). The contraband flown in was exchanged at a not-so-remote clandestine meeting point (a McDonald's parking lot in Nantes), where it was weighed and photographed so that the prisoners could confirm that the content on the Snapchat was what they intended. What's needed - a crime hedge against unsatisfied customers returning goods.

Nantes police, who busted the aerial quartet, said the drone-dropped shipments would be delivered directly to recipients waiting at the prison windows, and light jamming signal would be used to guide the ships to their location. The flights were flown in the middle of the night to four different prisons in western France, with each mission divided into five to ten missions, meaning multiple missions to the same prison were sometimes carried out in quick succession.

It is estimated that Air Colis made at least 50 shipments before police tracked down the gang in late September and revealed details of the operation.

The raid, which halted an illegal prison airlift, uncovered nine DJI Minis (including at least one original Mavic, according to police photos), several spare batteries, 500 grams of cocaine, a kilogram of marijuana and 900 euros ($950). Cash and thermal binoculars control the drone to identify the correct unit window at night.

"It's like an Uber delivering directly to the window," Nantes prosecutor Renaud Gaudeul said when announcing the arrest. "This is definitely not a trivial operation. As far as I know, France has never Things like this happen ... and it's good for criminals to see investigators doing their best as well."

If things continue this way, French police will need to further refine their counter-drone efforts. This summer alone, Air Colis is estimated to have transported more than 50 drones, bringing the number of confirmed drones entering French prisons in 2022 to 68, according to corrections officials. The number was more than 37 the year before. At this rate, the occupants of the car will be discovered the next time police conduct a search using a special app.

 

Latest News: A media article about multiple signal jammers disrupting French airport operations. Once the authorities discovered one, they discovered another, and then another!

 

Why It's Important:

1. GPS interference at airports can cause flight delays.


2. Many airlines will not let the plane leave the gate without a good GPS lock.


3. We have already seen cases of outages affecting landing systems. See: Events in Denver-Newark


4. In the worst-case scenario, an outage, even an unexpected one, can result in loss of life. Check out the thrills of Sun Valley.

What Else to Know:

• The EU STRIKE3 project has identified many cases of interference in or near airports.


• News reports like this about flight delays happen from time to time.


• In the United States, the FCC is the regulatory agency responsible for preventing such incidents and enforcing the rules.


• uUnfortunately, over the past two decades, the FCC has significantly reduced the number of personnel and equipment suitable for the job..

ANFR Fighting against phone jammer

Candice Clark 18 July 2023

In France, the National Spectrum Administration (ANFR) is responsible for enforcing rules banning radio jammers, including those that interfere with GNSS services. The availability of GNSS data is critical for many critical applications, so disruptions to GPS, Galileo, GLONASS and Beidou are as serious as cyber attacks.

ANFR's sworn representatives have the authority to investigate violations of national spectrum use regulations. They are often used to locate active gps jammer, either on a vehicle or in a fixed location. Catherine Gabay, ANFR Deputy Director for Frequency Monitoring and Enforcement, reported on some recent cases during the 2023 International Symposium on Navigation and Timing Technologies (ITSNT) in Toulouse.

In March 2023, an instance happened near Merville airport. The Directorate General for Civil Aviation (DGAC) notified ANFR of interference on the L1 frequency, which was disrupting flights and air ambulance helicopters. ANFR agents quickly reviewed in-flight information and discovered a GNSS jammer aboard a commercial vehicle. The police were brought in to assist with the seizure of the equipment, and the driver was arrested.

 

 

Cellular interference involves the use of equipment that interferes with radio or wireless signals

 

Cell destruction can be done with a device placed about 30 feet away from the intended target or via a home camera.

CMPD says thieves have figured out how to bypass security cameras and use technology in some burglaries.

This is called "cell interference" and occurs when a person uses a device to interfere with a radio or wireless signal.

According to the Federal Communications Commission, "It is a violation of federal law to use a phone jammer, GPS blocker, or other signal jamming device designed to intentionally prevent, interfere with, or disrupt authorized radio communications." A business, classroom, residence or vehicle. "

Cell destruction can be done with a device placed about 30 feet away from the intended target or via a home camera.

Video from a south Charlotte neighborhood shows a suspect sneaking through yards at night, but not all of the incident was caught on camera.

"Anytime you have wireless devices, whether it's Wi-Fi or whatever, you know people are going to find a way - how to jam them, how to try to prevent something from communicating," CPI Security Customer Operations said.

Within a few moments, someone is visible on camera, but as cells burst, with the push of a button or button, the person disappears or is not recorded.

CMPD says this problem has been seen in some break-ins in south Charlotte

"We haven't seen any activity like this, so we're aware of that and the most important thing is making sure we have the best technology and the latest technology," Shocknesse said.

WBTV asked him which devices are more susceptible to cellular interference

"I think it will work on some older wireless devices that don't have encryption," Shocknesse said.

Newer security systems and surveillance systems have better encryption and are more secure, he said.

"I really don't think we can emphasize enough the importance of having cameras and some onboard video," Shockness said. "The cameras we put in there are equipped with storage so if something goes wrong, you can still record what happened and report it to the police."

To complement this advice, he said the best solution to prevent cell phone interference is to use current encryption technology and wired devices rather than WiFi.

To prevent break-ins, simple tricks such as maintaining good lighting, turning on alarm systems and trimming shrubs to a height of no more than one meter can be effective.

 

Drones are increasingly being used for phone a variety of purposes, from surveillance to package delivery to destroying equipment on the battlefield. The need to control and eliminate these devices is becoming increasingly urgent. Against this background, the "Drone Off" anti-drone rifle emerged and is currently on display at the Partner 2023 exhibition in Serbia. The device can phone interfere with communication signals between drones and their operators, providing an effective solution to potential drone threats.

 

Serbia showcased Drone Off, a new anti-drone rifle developed by the company Iritel Beograd. The ability to neutralize drones is phone vital to militaries, and many are trying to find solutions to counter drone dominance. This is a new addition to those efforts.

The rifle operates in phone multiple frequency ranges, specifically 1164-1610 MHz for GPS L1/L2 and Glonass and 2400-2500 MHz and 5700-5850 MHz for remote control and video transmission. The transmitting power is 78W, which can interfere with UAV signals within a radius of 2.5 kilometers. The rifle weighs 3 kg and the included backpack weighs 10 kg. It uses sweep/multiple sweep type jamming signal and is equipped with a helical antenna with a gain of 12 dBic and an angle of 42°. The rifle operates in a temperature range of -25°C to +50°C, is battery powered, and features a battery status indicator light.

There are a variety of counter-drone technologies on the market, from frequency phone jammer to lasers to birds trained to intercept drones. For example, LMADIS (Lightweight Mobile Air Defense Integrated System) is a portable drone jammer that entered service in July 2019 and successfully shot down an Iranian drone. Drone Off features portability and high transmit power, making it a viable option for a variety of scenarios.

The importance of such technology is phone particularly evident in conflict zones such as Ukraine. Drones are often used for reconnaissance, surveillance, and sometimes even to drop munitions. The ability to neutralize these drones can provide significant tactical advantages. Other devices, such as the EDM4S SkyWiper used by the Ukrainian Armed Forces, have also proven themselves in this regard.

With its impressive technical specifications and range, it provides a viable solution for suppressing drones in phone a variety of situations, including conflict zones such as Ukraine. The development and adoption of such technologies is critical to address the challenges posed by the increasing use of drones, not only on the battlefield but also in areas such as security.

 

 

PENTAGON: The United States Army is straining to phone fund the increasingly important electronic warfare wifi capabilities it has developed since the gps fall of the Soviet Union. The Army possesses over 32,000 short-range defensive jammer device to block roadside explosives, but an offensive handheld jammer will not be available until 2023, according to current plans.

"Can that be sped up?" "Yes," replied Col. Jeffrey Church, the Army's Pentagon staff's chief of electronic warfare. "Technology exists today that does a lot of things that we would like MFEW [the Multi-Function Electronic Warfare system] to do," he said, adding that some of it might even phone be purchased commercially by the Army.

However, with the Army decreasing faster than any other service and sequestration looming, "there's no money tree," Church told me in an interview. "So if you're going to grow a robust electronic warfare program, who's going to pay for that?"

where is the Army's electronic warfare today?

"I have a theory. I've got folks. "I have facilities," Church explained. "What we lack is equipment."

"If you go to a unit gps today in the Army and phone you say, let me see your 'electronic warfare equipment,' and you go to the EWO (Electronic Warfare Officer) and he opens up his wall locker, it's empty," Church went on to explain. "Right now, the Army relies on borrowing assets from other people," such as the Growler aircraft from the Navy.

"Our senior army leaders have known and continue to know that electronic warfare is something the Army must have," said Church, the Army's senior electronic warfare specialist. (The fact that the highest senior EWO is a colonel rather than a general demonstrates how nascent the field is). "It's a matter of resource prioritization and wifi where do you fall in those priorities."

What category does electronic warfare fit under? The Pentagon's fiscal 2016 budget contains $2.5 million for something called the Electronic Warfare Planning & Management Tool, which is a rounding error for a significant weapons program. EWPMT, which went into service in September 2016, is much-needed software that will allow electronic warfare forces to gather data from sensors such as Navy Growlers and the Army's DCGS-A intelligence network.

"EWPMT is what allows them to see the phone battlefield in the electromagnetic environment," Church explained, "so you can tell your commander, 'this is where we have interference.'" This is the situation. This is where the adversary is. I'm not sure what it is, but gps I'm getting some sort of signal."

EWPMT, on the other hand, is now a command-and-control system with nothing to command and control. The 32,000 CREWS gps blocker that defend wifi Army vehicles from roadside explosives are strong at short range, but they aren't connected to any type of network, so EWPMT can't utilize them as a data source, much alone manage them. For the particular circumstances of Afghanistan and Iraq, the Army possesses just a few longer-range systems purchased using emergency funding and/or quick equipping authorities.

"We got good technology into wifi the field to save soldiers' lives," he remarked. "We didn't get any programs of record, so we phone don't have budgets, we don't have base dollars."

The Multi-Function Electronic Warfare system is designed to address this issue. MFEW will be a network of sensors and wifi blocker deployed on various sized drones, ground vehicles ranging from Humvees to heavy trucks, stationary locations, troops' backpacks, and maybe helicopters.

Church underlined that, unlike Cold War electronic warfare units, MFEW will not require a specialized vehicle to carry it: "The Army can't afford it," he stated, and current miniaturized electronics don't require it. Instead, MFEW will ride on ground vehicles while they go about their regular tasks, giving data to and receiving commands from Army electronic warfare experts at the gps command post. MFEW will be another plug-and-play module on drones, to be used or not depending on the task, as many specialized sensors already are.

How near is this vision to becoming a reality? "Right now, MFEW is not a program," Church explained, limiting the Army's capacity to support it. MFEW is now a "concept" in the arduous process of becoming a formal Army requirement. "We're on about the fifth rewrite of the MFEW CDD (Capabilities Development Document)," Church stated in a statement. MFEW can become a program of record and receive base budget money after thephone CDD is completed and authorized.

The MFEW is expected to start service in 2023 and achieve full operational capability (FOC) in 2027. We're still playing catch-up till then.

"Guys like the Russians, guys like the Chinese, their surrogates, they've spent the last 20 years continuing the development and acquisition of an electronic warfare capability, whereas... the Army got out of the business," he stated. When the battlefield was brought back to life, he stated, "Army electronic warfare started from nothing, and it started from nothing in a combat environment where a lot of US soldiers were being killed or wounded due to the radio-controlled IED."

Church stated, "Now we have to take this to the phone next level, and MFEW is the next level."

Of course, all of this is taking place as the Pentagon's senior leadership assesses its electronic warfare portfolio. The newly formed Electronic Warfare Programs Council is the place to be; it is led by Frank Kendall, the undersecretary for acquisition, technology, and logistics, and Adm. James Winnefeld, vice chairman of the Joint Chiefs of Staff.

 

Electronic Jamming Tactics

Jamming has increased in sophistication as electronic warfare gps has developed and phone includes an array of tactics. Barrage jamming is performed against two or more frequencies phone. This can be useful when the aggressor does not know exactly which radio or radar frequencies their adversary is using. Nonetheless, they may know with reasonable gps certainty which phone waveband of frequencies they may be using. Spot jamming is performed against specific frequencies known to gps be in use.

The advent of solid-state electronics in the 1960s revolutionized jamming technology. It facilitates the development of complex phone digital radio frequency memory (DRFM) systems. These are particularly useful for jamming radar equipment. DRFM detects incoming radar signals, samples the signal, and then cleverly sounds an alert before retransmitting it to phone the radar. This new false signal could confuse radar by showing two or gps more targets where there used to be only one. The target may move faster or slower than its actual speed. This strategy is called deception gps jamming.

Likewise, DRFM can collect and send false signals to trick the radar into believing there is a more prominent or attractive target in its field of view than the one initially detected. This strategy is called temptation interference. In the long term, the emergence of artificial intelligence will make interference tactics and techniques increasingly sophisticated.

Jamming is the basis of the electronic attack mission. Electronic attack is a subset of the broader discipline of gps electronic warfare (EW), which is discussed in more detail elsewhere. Jamming was first used during World War II to attack radar and radio phone equipment. Both latter systems transmit phone radio signals. Radar does this to detect and track objects, radio does this to send and receive voice and data traffic.

In the simplest case, the purpose of cell phone jamming is to impair a radar or radio's ability to perform its mission, or even prevent them from completing it entirely. The jamming process also uses radio signals, but in a way that attacks these systems. Simply put, jamming is gps an attack using artificially generated radio interference. An example of how interference works can be seen when a car drives under power lines with the radio on. The sound of the radio was suddenly drowned out by interference. This is caused by electromagnetic radiation from power lines.

Interfering signals, called waveforms, are sent to the radar or radio's antenna. The antenna should detect the gps signal. To ensure this, the signal is sent at a frequency that the antenna can gps detect and that matches the phone frequency of the interfering target signal: If the radar sends a signal at a frequency of 3.6 GHz/GHz, the signal must be the same in the event of a malfunction.

However, successful radar or radio jamming depends on more than just the frequency of phone the interfering signal. Signal amplitude is also important. Let's consider a radio that receives amplitude traffic at a specific wattage. If the interfering signal is weaker than the signal received by the radio, these signals will remain uninterrupted. Interference signals were also detected, but were too weak to have a noticeable effect.

If the interfering signal is stronger than the traffic received by the gps radio, the former will be "washed away." In electronic warfare, jamming is effective when a radio or radar device is receiving rather than transmitting. This is because the incoming radio signal is already relatively weak. This reduces the power required for the signal jammers to be effective. To explain how improvisation works, imagine a violin soloist and a heavy rock band on the same stage. The solo violinist begins to play, but their music immediately becomes inaudible as the rock band begins. This does not mean that the phone violinist's music has stopped, just that the volume of the orchestra drowns out the soloist's voice.

There are three ways to determine the location of your Tracki GPS tracker using geolocation data.

1. Global Positioning System (GPS) functionality, which uses satellite signal jammers to determine location very accurately.

2. Connect to WiFi by tracking the router's MAC ID. If Tracki GPS Tracker cannot find a GPS signal, it listens to all nearby WiFi routers and reports their MAC ID to our servers, which have access to a map of wifi blocker routers and their locations around the world. Accuracy is approximately 100-300 feet.

3. A less precise method is often called "cell tower triangulation," which refers to how cell towers calculate a tracker's geophysical location.

What is Cell Tower Triangulation?

In a perfect world, the GPS tracker's signal would be picked up by three or more cell towers, allowing triangulation to function. If you know the distance to a place from each of three unique points, you may compute the approximate position of that location in respect to the three reference points. We know the locations of the cell towers that receive our jammer GSM signal at Tracki because we have access to mapping of all cellular tower locations worldwide, and we can estimate the distance of the GPS tracker from each of those antenna towers based on the lag time between when the tower sends a ping to Tracki GPS tracker and receives the answering ping back.

In rare situations, a GPS tracker's signal may be received by more than three cell towers, providing for even greater precision. Because there are frequently many cell towers with overlapping signal coverage regions in big metropolitan urban areas, GPS tracker pinpointing accuracy is pretty good. When the GPS tracker is not exposed to the open sky, such as when it is within a building or underground, and there are no Wi-Fi networks nearby, cell tower triangulation may be the only means to determine location if GPS signal is not accessible.

However, there are numerous areas with fewer cell towers available, such as on the outskirts of towns and in rural areas. When there are less than three cell towers accessible, locating a anti-tracking jammer device becomes significantly less precise. To have good coverage in cities with a lot more vertical structures that might be obstacles to GPS tracker transmitting and receiving, there must be a lot more cell towers spread. There are fewer cell towers in the countryside, and a GPS tracker's signal may be picked up by only one tower at a considerably longer distance.

 

Those places where the GPS tracker is only picked up by a single tower, and if it just has a single omnidirectional antenna, the accuracy is considerably worse.

 

 

Tracking accuracy in rural locations might range from 0.25 mile to several miles, depending on how many obstructions may be obstructing the tower's signal.

How does a GPS tracker work?

GPS, or global positioning system, uses 24 to 32 solar-powered satellites and ground stations to relay data to GPS-enabled devices.

The primary goal of GPS systems is to identify the exact location of an object or person in real time. The global navigation satellite system (GNSS) network is used by GPS tracking systems. Each satellite in orbit transmits microwave signals to a receiver. The GPS tracker's receiver then utilizes these signals to compute your precise location from at least four GPS satellites. Finally, your location is calculated when the system triangulates your actual position on the earth based on these distances to the closest meters.

The method is based on a basic mathematical idea known as trilateration. GPS receivers use the exact location of at least four satellites and the distance between them to estimate four values: earth latitude, earth longitude, elevation, and time. The position of the receiver is determined by the position and distances to a certain satellite. The precise position of a satellite is regularly sent to all receivers within line of sight, which normally necessitates an unobstructed sky. The precise moment the satellite broadcast arrives at the receiver determines the distance to a satellite. The time created by each satellite's atomic clock is relayed at predetermined intervals by the satellite.

 

What a GPS Tracking Device Is and How It Works

GPS tracking devices operate on the same concept, but instead of displaying information on the device, the gadget's CPU calculates its location and transmits the resulting data to a server over the Internet via the international GSM cellular network. That server offers a platform from which end users may monitor the device's present and historical path, speed, and alarms. All of this data is then delivered over the internet and shown on a desktop software or a smart phone jammer utilizing an iPhone or Android app.

Anyone may profit from a GPS tracking device. It may be used by company owners to monitor fleets, staff conduct, and by households to keep track of elderly, children, or pets. To prevent their luggage from being lost or stolen, travelers embed a GPS tracker in it.

Active trackers, on the other hand, use a SIM and a GSM transceiver to process and send data in real time. Dispatchers receive real-time information via the GSM cellular network, allowing them to keep a close eye on their assets or valuables. Cellular network services are paid for with monthly fees.

In the event that the GPS satellites signal is obstructed due to being indoors or by a structure, and there is no sky, the device looks for cell tower signals and attempts to determine rough position using cell tower signal strength triangulation.

The GPS tracker determine where the device is located and roughly estimate the distance between the cellphone towers by interpolating signals between adjacent towers. A precision of down to 300 feet may be obtained in urban areas where density of cellphone towers is very high. Rural and county side areas which has less towers per square mile may see many miles between base stations and therefore inaccurately determine locations often showing a location miles away from the device real location.

For conclusion, when GPS satellite signal is available that is preferable to use. But in those cases when a GPS tracking device is blocked from open sky by structures, tall buildings, trees or even heavy clouds, cell tower approximation can mean the difference between knowing a general area whereabouts of GPS tracker or being in a complete dark.

 

 

As a professional photographer and drone pilot, I've seen firsthand how drone technology has become mainstream (pun intended) in recent years.

But with great power comes great responsibility, and as our skies become increasingly filled with these high-tech devices, the need for regulatory and control measures becomes increasingly clear.

Enter the world of drone jammers.

In this article, we'll explore the ins and outs of drone jammers, from basic functionality to legality. We will also discuss some practical applications of this technology.

Whether you're a drone enthusiast interested in the technology, a security professional looking to learn about drone defenses, or someone just concerned about privacy, this guide is for you and her.

Introduction to drone defense technology

Okay, guys, let's get down to business. What exactly is a drone jammer? Why should we care?

 

What is a drone jammer?

Imagine you are flying your drone and taking stunning aerial shots, and suddenly your drone starts to react. It doesn't respond to your controls and seems to have a mind of its own. My friend, you may have just encountered a drone jammer.

Simply put, a drone jammer is a device designed to interrupt the control signal of a drone.

It acts like a drone party killer, ruining the party by emitting electromagnetic noise on certain radio frequencies.

These frequencies cover the same radio and GPS signals the drone uses to operate, effectively grounding it.

 

 

The development of drone technology

Now you might be asking yourself, "Why would anyone want to stop drones?" Well, like any technology, drones can be a double-edged sword. On the one hand, they've revolutionized industries from film production to agriculture, providing a bird's-eye view that was previously only possible via expensive helicopter flights.

On the other hand, they also found a whole lot of mess when it came to privacy and security issues. Imagine a drone hovering outside your window, or worse yet, a drone being used for illegal activity. Not that funny, right?

 

 

The need for drone jammers

This is where drone jammers come into play. They're essentially a way to keep drones away from places they're not supposed to go. Think of them as the gatekeepers of the sky, preventing unwanted drones from entering restricted airspace.

But it's not just a matter of privacy and security. Drone jammers also play a vital role in ensuring safety. Because the last thing you want is for a drone to collide with a passenger plane.

 

 

How drone jammers work

Picture this: you are attending a rock concert and trying to have a conversation with your friend. But the music is too loud and you can't hear each other. This is essentially how a jammer works.

Drone jammers emit electromagnetic noise at certain radio frequencies, similar to loud music at a concert. This noise drowns out the radio and jammer GPS signals the drones use to operate, effectively drowning them out.

The impact of drone jammers on drones

So what happens when a drone is hit by a jammer signal? Well, it's a bit like getting lost in a strange city without a map.

Most drones respond to jamming signal by returning to their starting point. This is their way of saying: "I'm lost and I'm going home." In some cases, a drone jammer can land a drone at a scene for forensic investigation.

 

 

How to jam drone signals

Now, before you get any ideas, I want to make one thing clear: jamming drone signals should not be attempted at home. This is a complex process that requires a deep understanding of radio frequencies and drone technology. Plus, it's illegal in a lot of places (but we'll get to that later).

That being said, it's still interesting to understand how the process works. A drone jammer's frequency is generally assigned at 2.4Ghz or 5.8Ghz, which are public frequencies not assigned to manned aircraft, public broadcasts, or cell phone signals.

The jammer projects its signal in the shape of a cone, and when a drone gets hit with the signal, it typically returns back to its point of origin or lands on the spot.

 

 

According to a report in Israel-based newspaper Haaretz, the Israeli Defense Forces intensified GPS jamming in the region to prevent drone assaults by Hamas and Hezbollah.

According to the IDF, Israel is interrupting satellite navigation systems "proactively for various operational needs." "Citizens should be aware that the disruption can cause various and temporary effects on location-based applications," the Israel Defense Forces (IDF) told Haaretz.

According to the analysis, this will have two effects on GPS services. For starters, GPS signal reception can be fully disabled. Second, it may be faked, which means it can send bogus location data to the device.

GPS receivers may be found in mobile phones jammer phone, aircraft, ships, and vehicles. They receive signals from many satellites at the same time and utilize them to compute their own precise location and altitude.

These identical receivers may also be found on cruise missiles and drones, where they are used to direct them to their destination. Any army organization interested in thwarting such an attack may emit forcefully on the required frequency band, preventing the GPS blocker device from receiving any satellite signal and completely disabling its operation.

Spoofing is a technique in which the signal mimics the genuine satellite signal and hijacks the GPS receiver. Once the receiver has locked on to the bogus signal, the disrupter will supply it with fake data, forcing it to compute and show an inaccurate position and altitude. This can result in the receiver reporting its genuine position dozens, if not hundreds, of kilometers away.

According to Haaretz, Israelis had GPS troubles last week because the IDF was apparently attempting to prevent Hezbollah's GPS-guided drones from entering far into Israel.

The publication said that Israelis are being impacted, citing an example in which a person from Haifa said his phone incorrectly indicated his position as being in the northern border area while being in Haifa. Residents in the West Bank said that their phones notified them that they were close to the Gaza border.

However, this may cause problems with the IDF HomeFront Command app, which provides information based on the user's phone location. According to the publication, blocking the app or the GPS transmitter on people's phones might result in a false signal.

 

Starlink and other low-Earth orbit constellations face new security risks

Russia's invasion of Ukraine in 2022 really threw Ukrainian communications into a tailspin: Shortly before the invasion, Russian hackers disabled Viasat satellite ground receivers across Europe. Then entrepreneur Elon Musk stepped in and offered access to Starlink, SpaceX's growing network of low-Earth orbit (LEO) communications satellites. Musk soon reported that Starlink was suffering from cell phone jamming attacks and software countermeasures.

In March, the U.S. Department of Defense (DOD) concluded that Russia was still trying to block Starlink, according to leaked documents from U.S. National Guard pilot Ryan Teixeira seen by The Washington Post. According to the "Defense One" website, the Ukrainian military also blamed the Starlink problem on Russian gps jamming. If Russia blocks low-Earth orbit constellations, this will be a new height in the silent war between space and earth communications.

"There's really not a lot of information about it," said Brian Weeden, program director at the Secure World Foundation, an NGO focused on space governance. However, Weeden added, "My sense is that Starlink is harder to jam or interfere with [than GPS satellites]."

LEO satellites face new security risks

Regardless of their altitude or size, communications satellites transmit more power and therefore require more energy to jam than navigation satellites. However, low-Earth-orbiting satellites orbiting the Earth at altitudes of 2,000 kilometers or less switch frequently, which "results in delays and creates more interference" than large geostationary satellites, said Mark, professor of data protection and data protection. Mark Manulis said. Applied cryptography at the Cyber ​​Defense Institute (CODE) of the Bundeswehr University Munich.

Security and communications researchers have mostly studied defenses and countermeasures behind closed doors, but several publications and open-source research have revealed how unprepared many low-Earth orbit satellites are for a direct attack, and what defenses may be needed for future low-Earth orbit satellites.

For years, private companies and government agencies have been planning low-Earth orbit constellations, each with thousands of satellites. For example, the Department of Defense has been designing its own network of low-Earth orbit satellites to complement its more traditional geostationary constellation for more than a decade and has begun awarding contracts to build it. University research groups also launch miniature standardized CubeSats (CubeSats) into low Earth orbit for research and demonstration purposes. This proliferation of satellite constellations coincides with the emergence of off-the-shelf components and software-defined radio-both of which make the satellites more affordable, but perhaps less secure.

Russian defense authorities have commissioned a system called "Tobol" to counter jammers that could interfere with Russian satellites, journalist and author Bart Hendricks reports. This means that either Russia can deliver jamming signals to satellites, or it suspects that its adversaries can.

Many agencies and organizations launching the latest generation of low-cost satellites have yet to address the biggest safety issues they face, researchers write in the 2022 Low Earth Orbit Safety Report. This may be because one of the lures of low-Earth orbit is the relatively cheap ability of new hardware to handle smaller tasks.

"Satellites are getting smaller and smaller. Their purpose is very clear," said Ijaz Ahmad, a telecommunications security researcher at the VTT Technology Research Center in Espoo, Finland. "Less resources are devoted to computing power, processing, and storage." Lower computing power means less encryption capabilities and a lower ability to detect and respond to outages or other proactive outages.

The rise of software-defined radio (SDR) is also making it easier to deploy hardware for new missions, including the ability of small satellites to cover multiple frequency bands. "When you make it programmable, you provide some kind of remote connection to that hardware so that you can program it. But if you ignore the security aspect, there are serious consequences," Ahmed said.

 

Bloody ground attacks by Hamas armed militants shocked Israel, but there were also surprises overhead, says a Brock University professor.

DRONES IN ISRAEL AND UKRAINE

This seems to be the first conflict where Hamas has successfully used armed drones. Some are quadcopters that operators fly via remote control. They can precisely drop explosives onto small targets - like an Iron Dome system. Videos online show them attacking people, a watchtower and a tank.

Ukraine has effectively used similar quadcopters against Russian military targets. They sometimes drop explosives right down an armoured vehicle's open hatch.

However, technology is developing rapidly, in many cases, faster than the defence industry or NATO can react. For example, many ‘traditional' countermeasures against small UAS rely on electronic jamming of the Command and Control (C2) link between the ‘drone' and its remote control. Many current COTS products are, however, able to navigate autonomously to a given coordinate or can be controlled via a Global System for Mobile Communications (GSM) network from the operator's mobile phone. These features make jamming either completely useless, since the C2 link is no longer required to navigate, or unavailable, because of peacetime restrictions that prohibit the signal jamming of frequencies that are in use by the public.

The Space Domain

SATCOM is an essential part of BLOS UAS operations. But COTS UAS also utilize PNT signals provided by respective satellite constellations. Within the limits of the ‘Outer Space Treaty', countermeasures against space-based communications and PNT may be a legitimate option to defend against an entire fleet of adversary UAS. This does not necessarily require kinetic engagements by anti-satellite weapons. Indeed, ground or space-based jamming capabilities could be effective without risking the creation of large amounts of debris which could render entire orbits unusable for mankind.

Depending on the country and its domestic laws, which are applicable during peacetime, circumstances may prohibit certain types of countermeasures and limit the options for defending against UAS. These possibly prohibited countermeasures include kinetic engagement of airborne UA, cell phone jamming of publicly used frequencies such as GSM or wireless networks, or interference with the commercial PNT signals.

Additionally, non-kinetic measures such as jamming radio frequencies or PNT signals may affect public and commercial communications infrastructure and therefore, may be restricted or completely off-limits. Especially in peacetime, countermeasures have to be balanced against potential adverse impacts on critical communication systems and possible economic losses

Drug Cartels. In Mexico, drones have been extensively used for drug trafficking purposes in the region of the Mexico-US border as their use significantly lowers the risk of being caught. The route of the drone is pre-programmed and due to its autonomous capability, it cannot be blocked by electronic jammers at the border. The cartels in Mexico also use so-called potato bombs - hand grenadesized IEDs - in attacks on each other.

Both categories, commercially available drones as well as military UAS, should be considered ‘autonomous' in the way that they probably no longer require a permanent command and control link to fulfil their mission. This eliminates many of the current countermeasures which rely on gps jamming their radio transmissions.

Most UAS use a dedicated PNT data link to determine its precise location, and this link must be maintained to ensure mission success. The PNT signal strength measured at the surface of the Earth is roughly equivalent to viewing a 25-Watt light bulb from a distance of 10,000 miles. This weak signal can easily be jammed by a stronger power transmission in a similar frequency.

Any radio navigation system is generally vulnerable to interference. A typical patch antenna used to receive PNT signals must be able to receive them from virtually the entire sky. The advantage of this omnidirectional design is that even signals from satellites, which are just above the local horizon, can be received. However, this design is susceptible to a broad range of interference and drone jamming.

 

Top prosecutors across the country are again calling on Congress to pass legislation that would allow state prisons to interfere with cellphone signals smuggled to inmates. According to lawyers, the devices allow people to plan

violence and commit crimes.

"We simply need Congress to pass legislation giving states the authority to implement cell phone jamming systems to protect prisoners,

guards and the public at large," 22 prosecutors wrote in a statement. Wednesday's letter to House Speaker Kevin McCarthy and Senate Majority Leader Chuck Schumer.

Wilson's office said it plans to contact Democratic prosecutors and does not believe the matter is partisan.

The letter, obtained by The Associated Press, cites several crimes that lawyers say were orchestrated by inmates using contraband cellphones, including a drug conspiracy in Tennessee and a double murder ordered by an inmate in

Indiana.

They also led a gang siege at a South Carolina prison in 2018 that lasted more than seven hours and left seven inmates dead. One prisoner described the bodies as "literally stacked on top of each other, like a horrible pile of wood."

Corrections officials blamed illegal cellphones for the unfolding violence, the worst prison riot in the United States in 25 years.

"By preventing prisoners from using prohibited cell phones, we can prevent serious drug trafficking, deadly riots and other crimes," prosecutors wrote.

To render the phones - which are smuggled into hollow footballs, implanted by corrupt employees and sometimes dropped by drones - worthless, prosecutors are asking for changes to a nearly century-old law A historic federal

communications law that currently prohibits state prisons from using signal jamming technology to suppress illegal cellphone signals.

Efforts to crack down on illicit cellphones in state prisons have been going on for years, and South Carolina Corrections Director Bryan Stirling is leading an effort by correctional directors across the country to demand more

technology to combat their use of smuggled phones. the behavior of.

In a progressive victory in 2021, the FCC passed a decision allowing state prison systems to work with cellphone providers to sequentially apply for permission to identify and shut down illegal cellphone signals. South Carolina

was the first state to request use of the technology, but Sterling told The Associated Press on Tuesday that the state has not yet taken any action on the request.

Sterling said federal prisons can jam cellphone signals behind bars, but that is not currently the case.

CTIA, the wireless industry trade association, opposes interference, saying it could impede legitimate calls. However, CTIA told the commission that it has "successfully worked with its member companies" to "cease service for

prohibited devices pursuant to court orders received," according to a 2020 FCC filing.

CTIA and FCC officials did not immediately respond to emails seeking comment on the new wave of subversion.

Congress has previously considered blocking the legislation, but has yet to sign any bill or even hold hearings. U.S. Sen. Tom Cotton, R-Ark., reintroduced the measure in the last Congress in August.

"We're not going to stop advocating for this," Wilson told The Associated Press on Tuesday. "I can only hope that at some point Congress will take notice."

 

Drone signals can be jammed by using jamming signals to disrupt communications between the drone pilot and the drone. If you want to know more about whether you can jam a drone signal, read my complete guide - click here to go to the article.

Jammers work by emitting a much stronger signal than a remote control. They may interfere with radio signals and flight data as well as any video connections. The purpose of interference is to distort the signal to the point where the receiver simply cannot recognize it or to cause system failure. This is one way to legally stop drones and hijack communications.

Unless the government gives you permission, you're unlikely to buy a particularly large drone jammer.

There are a number of laws and regulations that may overlap with drone jamming technology, as well as a number of communications laws that govern the disruption of public communications frequencies:

US code

"No person shall intentionally or maliciously interfere with or disrupt radio communications of any station licensed or authorized by or under this chapter or operated by the United States Government."

- 47 US Code § 333 - Willful or malicious interference

The code means that personnel operating jammers must be licensed and authorized by the federal government.

If a drone jammer is used on a drone, there is a risk that the drone will fall from the sky, causing property damage and personal injury. This level of disruption could lead to the possibility of people suing you based on the damage caused by using a drone jammer.

You can jam drone signals by purchasing a drone remote control and using a signal booster to confuse any nearby drones. However, this may not work unless the drone is closer to you than the pilot.

Congressman David Kustoff (R-TN) and Senator Tom Cotton (R-AR) have introduced the Cellphone Jamming Reform Act, a bill aimed at addressing the issue of contraband cellphone use in federal and state prison facilities. The purpose of this legislation is to allow prisons to utilize cellphone jamming systems in order to protect inmates, guards, and the wider public from potential harm.

According to Congressman Kustoff, putting an end to the illicit use of contraband cellphones within correctional facilities will have an immediate impact on reducing crime rates, enhancing public safety, and relieving the burden on our overwhelmed correctional systems. He stresses that this act represents a crucial initial step towards tackling the current crime crisis faced by America. Congressman Kustoff expresses his pride in collaborating with Senator Cotton to introduce such pivotal legislation and urges fellow members of Congress to offer their support.

Senator Cotton highlights how prisoners have been exploiting contraband cellphones for engaging in illegal activities outside prison walls, including orchestrating attacks on rivals, promoting sex trafficking operations, facilitating drug trade, and conducting business transactions. The use of cellphone gps jamming devices can effectively halt these criminal endeavors; however, current regulations under the Federal Communications Act prevent correctional facilities from employing this technology. This bill seeks to rectify this issue so that criminals serve their sentences without posing any risk whatsoever to society at large.

The Cellphone Jamming Reform Act has received endorsements from multiple state attorneys general, including Tennessee Attorney General Jonathan Skrmetti, Arkansas Attorney General Tim Griffin, South Carolina Attorney General Alan Wilson, Oklahoma Attorney General Gentner Drummond, Virginia Attorney General Jason Miyares, Indiana Attorney General Todd Rokita, Ohio Attorney General Dave Yost, Alaska Attorney General Treg Taylor. The Act is also supported by the Major County Sheriffs of America, National Sheriffs' Association and the Council of Prison Locals.

According to Tennessee Attorney General Jonathan Skrmetti

"The only way to stop the illegal use of cell phones in prisons is through jamming signal. When individuals are incarcerated, they should not be allowed to maintain contact with criminal organizations on the outside. I commend Congressman Kustoff for his unwavering commitment to protecting our nation from organized crime."

Arkansas Attorney General Tim Griffin stated

"Congress needs to pass the Cell Phone Jamming Reform Act without delay. Prisoners are using contraband phones to carry out criminal activities from behind bars. We have the technology to enhance security and put an end to this illicit behavior; it's time we utilize it. I haven't heard any valid reasons why we should facilitate criminals and enable convicted felons to continue their criminal enterprises while in custody."

Background:

• The use of contraband cellphones is a pervasive issue within both federal and state prison facilities. Inmates exploit these devices to engage in a wide range of illicit activities, such as orchestrating hits on individuals outside the confines of the prison walls, operating illegal drug enterprises, facilitating unlawful business transactions, promoting sex trafficking, and coordinating escape attempts that put correctional staff, fellow inmates, and the public at risk. Incidents involving contraband cellphones have been reported nationwide.


• Over the past five years in South Carolina alone, there have been four significant cases of drug trafficking where operations were conducted clandestinely within prison walls using contraband cellphones. Notably, the most recent operation was directly linked to a Mexican drug cartel. Furthermore, in 2018, inmates affiliated with gangs orchestrated a merciless assault resulting in the deaths of seven inmates and numerous injuries through their unauthorized use of cellphones in a maximum-security facility.


• In Oklahoma, 69 defendants were found guilty of participating in a "drug trafficking operation that was primarily directed and controlled by incarcerated gang members using unauthorized cellphones from their state prison cells."


• In Tennessee, an inmate utilized an illegal cellphone to orchestrate drug conspiracy deals by sending a package filled with methamphetamine to his significant other.


• In Georgia, prisoners employed illicit cellphones to carry out fraudulent calls, demanding payment and even sending photos of injured inmates to their relatives while requesting money.


• As indicated by the Indiana Department of Corrections, during the previous year (2022), a gang enforcer incarcerated within Indiana Department of Corrections ordered a double homicide through the use of an unauthorized cellphone within prison walls.


• According to The Wall Street Journal's report, Martin Shkreli, the disgraced pharmaceutical executive who was sentenced to seven years for securities fraud, continued making decisions at Phoenixus AG with the assistance of an illegal cellphone.

F.C.C. spokesman Clyde Enslin declined to comment on the issue or the Maryland case.

Wireless carriers pay tens of billions of dollars to lease spectrum from governments as long as others don't interfere with their signals. And there are additional fees. Verizon Wireless, for example, spends $6.5 billion a year building and maintaining its network.

"It is counterintuitive that this type of device has found a market at a time when wireless consumers' demand for improved cell phone coverage is clear and strong," said Jeffrey Nelson, a Verizon spokesman. These carriers also raise public safety concerns: criminals could use gsm blocker to prevent people from communicating in an emergency.

The CTIA, a major cellphone industry association, asked the F.C.C. on Friday to maintain the illegality of the interference and continue to pursue violators. The company said the move was in response to requests from the two companies to allow jammers to be used in certain situations, such as prisons.

The individuals who used the jammers expressed guilt about their vandalism, but some clearly had a mischievous side, and others gloated over the phones. "It was worth it just to watch those stupid teens in the mall get their phone hung up." Can you hear me? Noooo! Nice, "the jammer's buyer wrote last month in a review on a website called DealExtreme.

Gary, a therapist in Ohio, also declined to give his last name, citing the illegal use of the devices. Interruptions are necessary to get the job done effectively, he says. He runs group therapy sessions for people with eating disorders. During one meeting, a woman's confession was rudely interrupted.

"She was talking about sexual abuse," Gary said. "Someone's phone was turned off and they kept talking."

"There's no etiquette," he said. "It's an epidemic."

Gary said that despite the no-phone policy, calls always interrupt therapy. Four months ago, he bought a jammer for $200 and secretly placed it on the side of the room. He tells patients that if they are waiting for an emergency call, they should give the phone number of the front desk. He didn't tell them about the jammer.

Gary bought the jammer from a website in London called PhoneJammer.com. Victor McCormack, the site's operator, said he ships about 400 jammers a month to the United States, up from 300 a year ago. He says more than 2,000 holiday gifts have been ordered.

Kumaar Thakkar, who lives in Mumbai, India, and sells jammers online, said he exports 20 jammers a month to the United States, twice as many as a year ago. Clients include cafe and hair salon owners and Dan, a New York school bus driver, he said.

"The kids thought they were secretly hiding in their seats and using their phones," Dan wrote in an email to Mr. Tarka, thanking him for selling jammers. "Now kids don't understand why their phones don't work, but can't ask either because they'll get in trouble!" It's fun to watch them try to get the signal."

Andrew, an architect in the San Francisco area, said using jammers started out as fun and became a practical way to keep quiet on the train. Now he uses it more wisely.

"At this point, just knowing that I have the power to cut someone off is satisfying enough," he said.

One afternoon in early September, an architect boarded a local train and became a mobile vigilante. He sat next to a woman in her 20s who he said was "chatting" on her phone.

"She kept using the word 'like.' She sounded like a valley girl," said architect Andrew, who declined to give his last name because what he did next was illegal.

Andrew reached into his shirt pocket and pressed a button on a black device the size of a cigarette pack. It emits a powerful radio signal that interferes with the chatterer's cellphone transmissions as well as those of others within a 30-foot radius.

"She spoke into the phone for about 30 seconds before she realized no one was listening on the other end of the phone," he said. What was his reaction when he first discovered he could wield such power? "Oh my gosh! Liberation."

As cellphone use soars, making it difficult not to hear half of a conversation in many public spaces, a small but growing group of rebels are turning to a blunt countermeasure: cellphone jammers, devices that interfere with nearby mobile devices invalid.

The technology is not new, but foreign exporters of jammers say demand is increasing and they are sending hundreds of jammers to the United States each month, prompting scrutiny from federal regulators and the wireless industry last week. new worries. Buyers include cafe and hair salon owners, hoteliers, speakers, theater operators, bus drivers and, increasingly, public transport commuters.

The development is sparking a battle for control of the airspace over the ears. This damage is collateral damage. Insensitive talkers inflict mischief on the defenseless, while jammer device punish not only the perpetrators but also the more cautious chatterboxes.

"If there's one thing that defines the 21st century, it's our inability to back down for the benefit of others," said James Katz, director of the Mobile Communications Research Center at Rutgers University. "The caller thought he was rights outweigh those of those around them, and the disruptor believes his rights are more important."

Jamming technology emits radio signals so strong that they overload cell phones and prevent them from communicating with cell towers. Ranges range from a few feet to several meters, and equipment costs between $50 and a few hundred dollars. Larger models can be reserved to create no-call zones.

It is illegal to use gps blocker in the United States. Radio frequencies used by mobile phone providers are protected in the same way as those used by television and radio stations.

The Federal Communications Commission says first-time users of cell phone jammers could be fined up to $11,000. His law enforcement agencies have prosecuted several U.S. companies for distributing the devices and are also prosecuting their users.

F.C.C. investigators said Verizon Wireless visited an upscale restaurant in Maryland last year. The store owner, who asked not to be named, said he spent $1,000 on a high-powered jammer because he was tired of employees focusing on their phones instead of customers.

"I tell them, put your phone away, put your phone away, put your phone away," he said. They ignored him.

The store owner said F.C.C. investigators spent a week there, using special equipment designed to detect jammers. But the owner has turned it off.

Verizon investigators were also unsuccessful. "He went to everyone in town and gave them his phone number and said if they had any questions to call him immediately," the store owner said. He said he had stopped using the wifi blocker.

Of course, detecting the use of smaller, battery-powered jammers, such as those used by disgruntled commuters, would be more difficult.

 

In today's fast-paced world, high-speed Internet and mobile services have become necessities rather than luxuries. But as data services continue to evolve and mature, requiring higher Internet speeds, and as operating systems need protection, hackers and adversaries continue to interfere. For some, this involves hacking into wireless connections in homes and offices for the purpose of extracting personal or business data.

But whether they're targeting government agencies, private companies, or individual users, these attackers typically use high-power signal jamming devices - wireless portable devices that block communication between devices. Such jammers are also a means of defense for users seeking to escape these attacks.

With this dichotomy in mind, former Khoury doctoral student Hai Nguyen and his advisor Guevara Noubir, both members of the Institute for Cybersecurity and Privacy at Khoury College, have pioneered a novel approach that can essentially eliminate these high-performance cellphone jammer in the event that traditional techniques fail. This failure occurs because traditional technologies are designed for non-malicious interference, require mechanical moving parts that are slow to respond to interference, or require additional radio frequency bands to achieve resilience. Their technique, known as JaX, can circumvent these scenarios.

"When you use wireless communication, you want to make it as robust and reliable as possible. As researchers, we like to solve difficult problems, and this problem has always been there, "Nubier said. "We want to approach this problem from a unique perspective, which is to develop secure communication technologies for GPS and Wi-Fi."

Nguyen and Noubir started working on this machine learning-driven idea about a year ago, when signal jamming played a major role in the Russia-Ukraine war. As they built up large amounts of synthetic data and collected experimental materials, their goal was to build a kind of black box that could be placed in front of the network and seamlessly protect users. The solution does not require complex machinery, thus simplifying the process of eliminating high-power signal gps jammer.

"For data collection, we set up a test bench, and for transmitters, we used software radios, and for jammers and receivers, we used other radios," explains Nubier. "We sent a legitimate signal, and then we also sent interference. We receive them through two antennas that store data, so we know what we are sending and what is interfering.

"The cool thing about our work," he added, "is that we can get an adversary's jammer to emit a more powerful signal than a legitimate one, and we can eliminate the interference as if it never existed!"

Nubier believes the paper's findings could be useful for a wide range of individual and organizational users who want to avoid malicious attacks on their data.

"The fact that we were able to achieve a very low bit error rate shows that we can outperform an adversary that can transmit a hundred times faster than a legitimate signal," he said. "There can be an extremely noisy signal in the environment, but because we have JaX, we can estimate what the gsm jammer is really transmitting, subtract it, and just leave the legitimate signal."

While this process sounds promising, the benefits only matter if the technology is logically sound and affordable - two barriers that often prevent innovative technologies from becoming ubiquitous. But Noubier believes he and Nguyen have cleared that hurdle, too.

"Our machine learning model is compact, so if you're designing any new system, you can easily incorporate it," he says. "Again, if the Department of Defense wanted to integrate JaX, the cost would be negligible compared to other models, and the model would be much more efficient."

Noubir and Nguyen, who recently defended their dissertation and joined Meta as a research scientist, acknowledge that new approaches to old problems always need tweaking and fixing. Still, they expect JaX to solve long-standing network problems and want to bring it to market.

WINDSOR LOCKS: Tech-savvy burglars targeted homes in Connecticut and Massachusetts and broke into a home there after receiving details about the security systems from fellow homeowners, according to arrest warrants issued Friday.

Matthew Colon, 31, of West Springfield, Massachusetts, was arrested for conspiracy to commit first-degree burglary and conspiracy to commit second-degree burglary. Enrique Santiago, 37, of Springfield, Mass., was charged with first-degree burglary, possession of burglary tools, theft of a firearm and conspiracy.

Police said they expected to arrest a third man in the case, which was linked to other burglaries involving heightened surveillance and information about when the homeowner left, according to Colon's arrest warrant.

Early on May 20, 2022, a Green Manor Terrace resident called Long Island police to report that surveillance cameras showed two men walking through his backyard. The arrest warrant states that officers who stopped the burglary found a broken rear sliding glass door and a collection of discarded evidence near the home, including a Wi-Fi jammers, a portable radio, a glass punching tool, A crowbar and bolt cutters.

Burglars broke through the chain link fence and disabled security cameras with manual and Wi-Fi gps blockers, but the poolside cameras were beyond the phone jammer, Windsor Locks Detective Chief Jeff Lampson wrote in Windsor Locks range and continue recording. Affidavit Warrant. The homeowner reported $4,200 in cash missing, along with a man's watch, jewelry and his wife's 9 mm handgun, the search warrant said.

On May 26, a resident two doors down found a pillowcase containing a watch, a gun and other items the victims identified as belonging to them, police said. Police said the location of the bag of stolen goods and a backpack containing a WiFi jammer showed the thieves fled in different directions after the break-in.

Lampson said Friday that federal law prohibits the use or operation of jamming devices and that federal investigators are interested in the case. He said police in the area have noticed the devices are increasingly being used in burglaries.

In this case, however, police say it was DNA that led to the thief's demise. During a search of the Green Manor Terrace property on May 23, a homeowner told police she found a pair of gloves she had never seen before and handed them over to investigators. Police submitted swabs from the gloves and other evidence they suspected the thieves had come into contact with to the state forensic laboratory.

Lampson wrote in the arrest warrant that on Aug. 16, the San Diego lab reported "criminal conduct" with DNA on the gloves. Police said the same DNA was linked to two previous burglary investigations, including a 2010 car break-in in Middletown and a 2012 break-in in South Hadley, Mass., where a gun was stolen. Santiago was arrested in both cases, according to arrest warrants.

Santiago, through his attorney, told Windsor Lock investigators that a man who drove a black sedan and whose father owned a tuning company coordinated the break-in at Green Manor Terrace, the warrant said. When Lampson asked the homeowner if he knew anyone matching that description, the man immediately identified Colon, a co-worker at a home health care company in East Longmeadow, Mass., Lampson wrote in the arrest warrant.

The homeowner said he considered Colon a friend and told him about a trip to Long Island last May, the warrant said. The victim also said Colon and his father helped him remodel the home, the warrant said. He said Matthew Colon had been to his home multiple times and was aware of the security camera system, the warrant states.

When faced with the victim's statements and evidence of the burglary, Colon told police he was "tricked" into the burglary plan by a third suspect in the case.

The suspect's girlfriend also worked in home health care with the Colon and Windsor Locks victims. Lampson wrote in the arrest warrant that other workers at the company reported break-ins at their homes in Massachusetts, including one woman who said Colon had come to her home to help repair a gazebo before the break-in.

Cellphone records showed calls between Colon, Santiago and the unidentified suspect in the Windsor Locks burglary before and after the break-in, the warrant stated. Police said the third suspect is a felon with a long criminal record that includes armed robbery and numerous burglaries.

Santiago also has a long rap sheet, including convictions in Connecticut for burglary and larceny, the warrant stated. Massachusetts investigators said they believe he is part of a criminal organisation involved in targeted burglaries, according to the warrant. He posted US$150,000 bond and is scheduled to appear in state Superior Court in Hartford on May 31. Colon posted bond of US$100,000 and is to appear in court on May 2.

 

Ensuring the safety and security of both staff and inmates within correctional facilities is of utmost importance. Implementing stringent security measures is crucial to maintain control and prevent dangerous situations from arising. Sadly, the presence of cellphones in prisons poses a significant threat to this goal.

 

One of the main challenges that correctional facilities face is preventing contraband items from entering the prison. Traditional security measures such as body scanners, metal detectors, and thorough searches often prove ineffective in detecting smaller items like cellphones. Inmates and their accomplices have become increasingly creative in concealing these devices, exploiting vulnerabilities in the system.

 

Once cellphones find their way into prisons, they become powerful tools for organizing criminal activities within and beyond the facility's walls. Gang leaders, drug dealers, and other inmates can use cellphones to coordinate illicit operations, intimidate others, and even continue conducting their illegal businesses from behind bars.

 

In response to the Greenville Veteran's Suicide Incident, correctional facilities are under immense pressure to strengthen security measures and address the issue of cellphone access within prisons. The incident demonstrated the urgent need for innovative solutions and strategies to combat this growing problem.

Shortly before noon on Sept. 11, 2018, a former Army soldier named Jared Johns lay in bed, turned on his iPhone camera, and said goodbye to his family.

 

Near the end of the two-minute video, Johns' eyes widened as a text message read on the screen: "She's calling the police and you're going to jail," it read.

 

Johns, who had served in Afghanistan, took a deep breath, placed a 9mm pistol under his chin, and pulled the trigger.

 

The 24-year-old veteran is one of hundreds of former and current service members who have fallen victim to a "sextortion" conspiracy. The scheme that led to his suicide involved scammers posing as underage girls on dating sites. Prosecutors said they sought to extort men who responded to their solicitations.

 

But the most startling aspect of the plot in Johns' case was that it was allegedly carried out by inmates at Lee Correctional Institution, a maximum security prison in South Carolina about 150 miles east of Greenville. And the inmates did it using smartphones - banned devices that should have been blocked by the prison's $1.7 million "managed access system."

 

Now prison officials and some federal agencies have proposed purchasing an even more complex and potentially more expensive technology to stop illicit cellular and Wi-Fi messaging from contraband phones in prison: a jammer that will block all calls within its range.

 

"Inmates are incarcerated physically, but they're still free, digitally," said Bryan P. Stirling, the director of the South Carolina Department of Corrections, who has been on a mission to get signal jammers in prisons since 2009.

 

But some experts warn that jamming technology, which the federal Bureau of Prisons recently tested in a South Carolina prison, could put the public at risk by interfering with 911 calls and other cellphone service nearby. For rural prisons, the concern focuses on drivers on local roads and highways. Plus, they say, the technology probably won't work.

 

"They're taking an internal problem and impacting people who are not involved," said Richard Mirgon, a former executive at the Association for Public-Safety Communications Officials. "It's tantamount to saying, ‘Why not jam up the freeway to keep people from speeding in the side streets?' It's just so extreme."

 

 

Problems with the best solution

The best solution, according to telecommunications companies and advocates for prisoners' rights, would be to stop the influx of cellphones into prisons. But that has proven difficult,

especially at a prison like Lee, which has a long history of serious phone-related incidents. Inmates there have used contraband cellphones, for example, to order a hit on a corrections officer who was shot almost to death in 2010 and to publicize prison riots twice in the past four years.

 

Sex, drugs and cellphones:Relationships between guards, inmates unravel SC prisons

 

Prison officials at Lee say they have tried to stem the tide. In 2017, the corrections department felled large trees that loomed over the prison to stop drones from dropping off packages of cellphones. That same year, the department spent $8.3 million to install 50-foot netting at the perimeter of its prisons, including Lee, in hopes of stopping couriers from throwing backpacks of cellphones over fences.

 

Corrections officials say these solutions reduced the number of cellphones in state prisons. In fiscal year 2017, prison guards confiscated 7,482 phones, batteries or chargers in the state's facilities, which house more than 21,000 people. In the fiscal year that ended in June, officials collected 3,900. Chrysti Shain, a spokeswoman for the corrections department, said that inmates now must spend thousands of dollars to acquire a phone.

 

Yet, the department acknowledges phones still get inside. Experts point to low-paid guards and prison workers who can augment their low pay by selling inmates contraband.

But even if cellphones get in, there should be no calls getting out. That's because of the nearly $2 million in technology that Lee officials purchased to block calls from unauthorized phones.

 

 

Challenges with cellphone signal blocking

In 2017, after clearing the treeline and setting up the nets, the corrections department hired Tecore Networks, a communications company, to install the system that is supposed to detect and block all calls made from contraband phones. The technology is supposed to work like this: If someone makes a call, the system compares the cell number to a predetermined list of prison staff phone numbers - called a white list -and then either allows the call to go through, or blocks it.

 

The wireless telecommunications lobby group CTIA, which represents some of the country's largest carriers and equipment manufacturers, has recommended that prisons use the managed access systems, as they are called. But it's unclear how many facilities across the country actually do. Shawntech, another private company that sells managed access systems to correctional institutions, says it provides the multi-million dollar systems to close to 350 jails and prisons.

 

Even engineers who back the system as a solution warn that it's not a silver bullet to stop all illicit calls, which can circumvent the system because of a very basic rule of how a cell tower works: If you can't see it, it can't see you.

 

When someone inside makes a phone call, the closest cell tower will pick up that signal. In a prison with a managed access system in place, the tower is usually located within the perimeter. But, for example, if an inmate stood behind a wall with water pipes, the cell signal would find the closest tower it could see, which would be outside the prison.

 

Also, cell companies often change the strength of a signal if customers in an area have bad reception. It's like listening to two conversations happening at once in the same room; it's easier for you to hear the loudest speaker. Whenever cell companies boost a signal, cellphones inside the prison will be able to find it more readily. It's a problem that Tecore flagged in a 2018 press release.

 

That's what South Carolina's corrections officials say happened at Lee, and how the inmates contacted Johns in the first place.

 

Current and former prisoners at Lee said they could use cellphones easily, even with the managed access system in place. This year, inmates at Lee were caught live-streaming on Facebook.

"Walk into one room, and it's fine; walk into another and you won't be able to," said a current inmate in the prison, who said he has used a prepaid Boost Mobile cellphone to make calls. His identity is not being revealed out of concern for his safety.

 

Tecore, which manages the prison's system, did not respond to multiple emails or calls over several weeks seeking comment.

 

 

Jamming all calls, even to 911

These problems explain why corrections officials and federal agencies have proposed using technology long opposed by the communications industry: cellphone jammers to stop all calls, even from phones owned by staff or emergency workers.

 

Unlike managed access systems, which allow people to make calls if their numbers are on an approved list, a jammer is indiscriminate in its reach and power to block all frequencies, including data and Wi-Fi. That's a problem for the nation's 911 phone system, which operates on a frequency close to the one commercial carriers use.

 

Only federal authorities can legally use jammers, and only in limited circumstances involving national security. But with the blessing of the FCC's Chairman Ajit Pai-appointed by President Trump in 2017- and the U.S. Department of Justice, prison jammers could become a possibility.

 

In September, the department and state officials put out news releases saying that a test at South Carolina's Broad River Correctional Institution showed that a micro-jammer could block calls inside a cell block while allowing "legitimate calls" a foot outside its walls.

 

But a technical report on the same test by the National Telecommunications and Information Administration was squishier. It noted that the test involved only one of the 14 gsm jammer required to block calls in half the cellblock. And it found that jamming was detected at least 65 feet away, though it said it was unclear how significant that interference would be to regular cell-phone service.

 

The telecommunications agency would not comment on the study.

 

Precise jamming - limited to a specific distance and also only to cellphone frequencies- is prohibitively expensive, especially for larger correctional facilities, said Ben Levitan, a technical engineer who has worked with the South Carolina corrections department in the past and read the NTIA's report.

 

That kind of jamming is "cool in theory, but it's impractical," he said.

UPDATE: A mobile man accused of interfering with emergency communications pleaded not guilty on Thursday, June 15, 2023. Trenton Lisak was charged with interfering with public safety communications and drug possession.

Prosecutors allege he used expensive, sophisticated equipment from an apartment in Ryan Park Towers. Mobile County 911 officials said communications in downtown Mobile were nearly paralyzed on June 6 and were disrupted the rest of the week.

The judge set a preliminary hearing for Lisak on July 19.

Ability:

Mobile, Alabama. (WALA) - Interference from expensive, "sophisticated" black market equipment disrupted police and emergency service transmissions for much of last week, according to law enforcement officials.

Police arrested Trenton Edward Lisak Saturday on a charge of interfering with public safety communications, a Class C felony punishable by one to 10 years in prison. He also faces drug charges. Prosecutors said the FBI is also investigating.

"This is an unusual charge," Mobile County District Attorney Keith Blackwood said Monday. "This is certainly something very serious. We need our law enforcement and first responders to be able to communicate, not just downtown but everywhere."

How unusual?

"This is a first for me," Blackwood said. "I don't recall any other case where this has happened - certainly not to this extent. That's a lot of equipment."

Lisak was arrested for theft, burglary, possession of a forged instrument and criminal mischief.

Mobile County District Judge Jennifer Wright set bail at $15,000, the recommended limit for the crime, and ordered 10 percent to be paid in cash. She also posted an additional $5,000 bond on the drug charge.

Additionally, the judge imposed a curfew between 8 p.m. 8 a.m. and ordered Lisak, 31, to stay away from the tower in Ryan Park downtown. Authorities said they found jammer device at the apartment complex that interfered with communications for all 57 law enforcement, fire and EMS agencies in the Mobile County Communications District.

That's also the home address listed on Lisak's booking information, but prosecutors told the judge investigators don't believe he lives there.

County Executive Robert Jackson described it as "very sophisticated cell phone jamming device placed in homes specifically designed to interfere with our frequencies."

Jackson added, "We actually had to modify our instrument to accommodate this."

911 system chief Charlie McNichol told Fox 10 News last week's outage effectively knocked out communications for a day.

"Last Tuesday this caused serious problems for the city centre," he said. "We actually have a tower site in Government Square. That's where the alarm came from. The first people who came here had serious communication problems."

Officials said it was unclear what the motive was. Blackwood said he had no idea what the defendant planned to do or where he obtained the equipment.

McNicholl said he didn't know if Lisak was just watching the chaos for fun, or if he was planning something more sinister and trying to disrupt communications as part of it.

"This individual was in possession of gps blocker that was purchased on the black market," he said. "It's illegal to even possess it. That's what's causing the problem."

How criminals use jammers device and defuses to compromise Wi-Fi security cameras

The new warning applies to anyone using wireless security cameras like Ring to protect their homes.

A Detroit woman says her Ring camera didn't capture the moment her car was stolen outside her home, and local experts say that's because criminals have become more tech-savvy.

Earlier this month, the woman said her car was stolen from her driveway and when she checked her Ring camera footage, she noticed the time was missing.

Chris Burns, owner of Techie Gurus, said security cameras that use Wi-Fi to record are more about convenience than safety. This is because Wi-Fi can easily be interfered with, preventing cameras from detecting people near your home, leaving criminals in trouble.

"Relying on wireless as a security aspect is a mistake," Burns said. "Wireless signals can easily be interfered with or blocked."

These scammers can use it like a WiFi jammer or deauther, which can be about the size of an Apple Watch.

If you stand close enough, the defuser will overload the WiFi system and force the WiFi camera to stop recording. Accessories only cost around $10 to $50. Jammers, on the other hand, cost between $150 and $1,000.

They are also extremely illegal, making jammers even harder to find. However, with the push of a button, powerful portable jammer can prevent WiFi security cameras from recording an entire street.

A Ring spokesperson issued a statement: "As with any Wi-Fi-enabled device, Wi-Fi signal interference can affect the performance of Ring devices. If customers are experiencing connectivity issues, we encourage them to contact Ring customer service."

How can customers protect themselves?

"For true security, it should always be hardwired, it should always be connected to Ethernet or something like that," Burns said.

A Ring spokesperson said that while the issue is well known, it is rare.

Burns said gps blocker are likely to become more popular as technology becomes cheaper, and it's important for people to be fully informed.

 

The Federal Communications Commission says illegal devices that block cell phone signals could pose a security risk.

The FCC has seen an increase in the sale of jammers devices that block cell phone calls, text messages, Wi-Fi networks and jammer GPS systems and could be used to wreak havoc in public places.

The small, battery-operated devices can be used to create "dead zones" in a small area (usually about 30 feet) and are used by movie theaters, restaurants and schools to keep people away from their phones. But they also disrupt emergency calls, can disrupt navigation near airports, and have been used near police stations to disrupt radio communications. FCC officials said they have noticed an increase in jammers banned under federal law entering the country. Many cheaper versions are imported from Asia and sell for as little as $95, according to the agency.

The sale, advertising, use or import of jammers is illegal under the Communications Act 1934, which prohibits the blocking of radio communications in public places.

The Federal Communications Commission (FCC) cited eight individuals and companies for ad-jammer ads on Craigslist.

According to the FCC, the jammers were advertised on websites in Orlando, Philadelphia, Austin, Mississippi, Charlotte, North Carolina, Washington, D.C., Cincinnati and Corpus Christi, Texas. Officials said they do not believe the cases are related.

"Merely advertising signal jammers on sites like Craigslist.org violates federal law. Signal jammers are contraband for a reason," FCC Enforcement Director Michele Ellison said in a statement expressed in. "One person's moment of peace or privacy may well endanger the safety and well-being of others."

According to the citations, most sellers advertised the jammers for "an undisturbed nap" on the bus, keeping classrooms quiet, or keeping the area "free of nuisances," but there was no suggestion that the device might be used for more nefarious purposes .

"We are increasingly concerned that individual consumers who use jammers appear to be unaware of the potentially serious consequences of using jammers," one of them was quoted as saying. "Instead, these operators mistakenly believe that their illegal activities are for personal convenience or should otherwise be excused."

But the FCC said at least one seller appeared to know the jammers were contraband.

Keith Grabowski reportedly advertised a "cell phone jammer, Wi-Fi jammer" on Craigslist in Philadelphia for $299.99. He said in the ad, "with few details given due to the nature of the item," that the jammer "is not a toy" and "I just want to get rid of it as quickly as possible."

"The nature of his complaint indicates that Mr. Grabowski was aware of the sensitive and/or illegal nature of the equipment he was selling on Craigslist," his citation reads.

Those facing charges have 15 days to remove the ads from the site and provide the FCC with information about where the jammers were purchased and to whom they were sold. Merely advertising a jammer for sale could result in fines exceeding $98,000.

The FCC has established a jammer reporting hotline to notify the agency of people who may be selling or using jammers.

"We intend to take more aggressive enforcement action against violators," Ellison said. "If we find you selling or operating a jammer, you will pay a high price."

Have you ever been annoyed by other people talking loudly on the phone and disrupting your morning commute?

It turns out there is a way to block these calls, but it's illegal and could cause serious security issues for others.

A controversial device simply and appropriately called a cell phone jammer can silence cell phones, CBS New York's Mary Calvi reports.

One commuter said: "There's a lot of noise, constant discussions, people telling each other what to have for dinner, what to do on the weekend and it makes it all tiring." This is where mobile signal jammer come into play.

He decided to put an end to the situation and used the device to cut off the phone signal. "You ask them nicely if they can turn it down a little bit, but they don't, and then we cut them off," he said.

He asked that his identity be kept secret because jammers are illegal.

Although the man said he wasn't afraid of getting caught, the Federal Communications Commission imposes stiff penalties on people who block other people's cellphones and GPS devices. These penalties can range up to $100,000, including jail time.

Although signal jammer device are illegal in the United States, Canada, the United Kingdom, and other countries, you can buy them online, and you can even watch them work on YouTube.

Criminologist Joseph Giacalone explains why cell phone jammers are problematic.

"They can jam emergency calls, they can jam police radios and traffic radios," he said.

However, these dangers don't seem to stop people from buying them.

"For example, many employers call looking for cell phone jammers so their employees don't have to be on the phone all the time," explains Yatri Trivedi of spytecinc.com.

Some devices knock out phones in shorter ranges of about 15-feet, while others can disrupt an entire cell tower, and there are apparently a number of people using them.

"I don't pay $400 a month just to hear people yapping on the phone for 20 minutes straight," the anonymous commuter said.

The FCC recently levied a $48,000 fine against a man in Florida who was caught driving with a high-powered gsm signal jammer in his car. Interestingly, the man said he used the device because he wanted to stop other drivers from talking while driving.

 

Cell phone jammers in the country's prisons are not enough to stop criminals inside from sending messages to others outside the prison.

That's the view of senior prison officials, and while network jammers (which they say can be used) are used to block cell phone signals in prisons, other interception techniques are needed for the system to be effective.

"Cellphone jammers are being used. However, to be truly effective they must be used in conjunction with other technologies such as WiFi jammers. We can see this happening in other jurisdictions. But it still needs to be used correctly here.

"So some prisoners have mobile phones and tablets but are unable to make calls. However, you can use your phone's data allowance or if you have access to a hotspot device or WiFi box, you can also make calls through social media apps. This includes WhatsApp , Facebook and Instagram etc. So the problem of communicating with the outside world remains. Communication is still a work in progress.

"In other jurisdictions, you'll see cell phone jammers used in conjunction with other interception devices to determine what frequencies those devices are using and then target those specific frequencies." If it doesn't, it's almost like a dreidel in the mud, "a senior prison Service source explained yesterday.

Acting Commissioner of Prisons Deopersad Ramoutar did not directly answer questions put to him recently about the function of mobile phone jammer, saying it was confidential information and not within the purview of the Prison Service.

On July 5, several contraband items were found and seized at Aruka Maximum Security Prison, including a Wi-Fi box.

The officer received the information and went to the cell block B of the prison.

Police conducted a search and found and seized a bag containing 53 grams of cannabis, mobile phones and Wi-Fi boxes in a cell near the toilet.

In another cell, police found and seized a bag containing 104 packs of cigarettes and marijuana weighing a total of 241 grams.

Two prisoners said they were in possession of the seized items.

On Friday, prison officials expressed concern about the use of drones over prisons, with one senior officer saying it was a "ticking time bomb" that needed to be addressed.

"All it takes is a drone, we can't catch it, it could drop knives or even guns and we could have a very serious situation." Everything we've seized so far has been contraband - cigarettes, marijuana, cell phones, chargers, etc. But if we miss even one, it could be a very dangerous situation for the prison and for the country."

Ramutar said the prison service had noticed an increase in the number of drones being used around prisons, especially in the last year, and had taken action.

He said that with the help of various branches of the state security services, most of the items dropped from the prison walls were confiscated before they reached the prisoners.

What happens when you take steps to ensure a little privacy by blocking your company vehicle's GPS tracker to hide your location from your boss? A New Jersey man discovered after his gps jamming disrupted "pre-deployment testing of the Ground Augmentation System (GBAS) at Newark Liberty International Airport" was fired from engineering firm Tilcon and fined nearly $32,000 by the FCC Dollar.

 

According to the FCC, cell phone jamming device have "no lawful purpose" and can only be "sold to the U.S. federal government for authorized official use." GBAS is being tested at Newark Airport and is designed to "provide aircraft near the airport with improved navigation signals to enable precise arrival, departure procedures and terminal area operations." On August 3, the FAA complained of a malfunction during testing. On Aug. 4, a police officer used "direction finding technology" to determine that GPS interference was coming from a red Ford F-150 pickup truck.

FCC agents interviewed the driver, who identified himself as Gary Bojczak, and admitted that he possessed and operated a radio device that interfered with GPS transmissions. Mr. Bojczak alleges that he installed and operated jamming device on company-provided vehicles to interfere with the GPS-based vehicle tracking system his employer installed on the vehicles.

This is the first time the FCC has skipped the warning and instead imposed a hefty fine of $31,875. Officials worked quickly, given that John Merrill, the U.S. Department of Homeland Security's position, timing and navigation program manager, told a GPS conference: "The FAA and FCC worked from March 2009 to April 2011 A single GPS jammer was developed "to locate a jammer operated by another truck driver on the New Jersey Turnpike."

CBS New York interviewed other company-tracked vehicle drivers who aren't opposed to such GPS tracking by employers. One driver said she had "nothing to hide" from her dispatcher, but there's a big market-even if it is illegal-for GPS jammers.

 

Let's give credit to the teacher who destroyed the phone signal in the classroom. This is just a place that needs them.

The news that Fivay High School teacher (and former professional wrestler!) Dean Liptak is in trouble for blocking cell phone signals in his classroom is completely the wrong reaction from the school administration (and let's be honest, the government).

Of course, what he was doing was technically illegal. The FCC says: "The use of 'cell phone jammers' or similar devices (signal blockers, GPS jammers or text message blockers, etc.) designed to intentionally block, interfere with, or disrupt authorized radio communications is a violation of federal law." Oops, It's not even illegal to sell jammers in the United States, but they're easy to buy overseas (as long as the retailer doesn't get caught). The only legal purchasers of such equipment are government employees.

 

Liptak is getting off light (five-day suspension without pay); a Florida man with a jammer in his car for months got fined $48,000. At least one priest has used a jammer after calls happened during sermons and even a funeral-and he supposedly got the go-ahead from the police.

Sure, the driver, and the priest, and the teacher may have used some questionable judgment since the signal blocker blocked more than just their limited locations. But they all jammed with the best of intentions, and perhaps Liptak had the best reason of all: to get the little brats we call our future to pay attention for once.

Back in the days of yore, in-class distractions were limited to things like seeing something out the window (SQUIRREL!), passing folded notes, or maybe sneaking in a comic book. Now, a student can do all that and a 1,000 other things on one screen. How does a teacher of any quality compete with YouTube, Snapchat, Trivia Crack, or even PornHub? Putting a filter on the local school Wi-Fi network doesn't mean squat to a kid with unlimited data from mommy and daddy's family plan.

Rather than condemn Liptak, society should look into ways to empower teachers who need this assist. The FCC and Congress should be creating exceptions to the Communications Act of 1934 upon which many of the cellphone jammers limitations are based. Businesses should be allowed to find new ways to make easily controlled jamming devices.

Because, let's face it, there are multiple places where it would be an excellent idea for jammers with limited, fine-tuned range, to be used judiciously:

At Home

Parents can try parental control and monitoring software all they like, but once a kid (or even the spouse or grandparents) gets the freedom of the smartphone with data plan, good luck trying to get them to talk during family dinner.

Just as a parent has the ability and right to cut off the Wi-Fi at home, they should have the option to cut the cellular signal if desired. Grabbing phones from hands to put them in airplane mode probably won't work, and making the house into a Faraday cage is an extreme only the tin-foil hat crowd should try. But an in-home cell jammer should be an option whenever desired or necessary. (Just keep that landline, folks.)

All of these examples are predicated on other lines being available for emergencies, or at the least someone having the expectation of mobility enough to get outside the jammer's range. For now, there's no way that even those with the best intentions could utilize the limited tech available in a way that wouldn't disrupt services well beyond the scope of their classroom, theater, office, or home, unfortunately. If you think there's an illegal jammer in use around you, visit the FCC online complaint portal or call 1-888-CALL-FCC (or 1-888-225-5322).

But before you do, consider if you really were harmed, or if maybe, just maybe, that hour without the cell signal was the best hour of your day. Besides, if your signal is jammed, you probably can't make the call anyway.

The Workplace

There's no question that in most offices, email and the Internet are absolute necessities. But are cell phones? In a survey by Pew Research, only 24 percent of adults with full- or part-time jobs listed a cell or smartphone as "very important" to getting their work done. In other research, 50 percent of bosses think a cell phone is a negative to workplace productivity.

There are plenty of places where it's actively dangerous to be using a cell phone-but the devices are probably snuck on to warehouse or assembly line floors all the time. If employers could jam signals but allow for emergency calls, no harm, no foul.

Restaurants

The sign should read: No short, No shoes, Using Phone, NO Service. Customers who can't bother to place an order with a server because they're in the middle of a call should get a 35 percent tip forced on their bill. Better yet, the bistro's jammer should cut this so-called customer off-if the call is so damn important, they can go outside.

Theaters

I've been on the wrong end of a couple of cell phone calls at movie theaters in the last few years. Namely, in the middle of a movie, people's phones not only went off, but the idiot in question answered, then proceeded to have a conversation, at normal volume, as if that's perfectly okay, and not grounds for justifiable homicide. (At one of those films-the execrable Land of the Lost, so perhaps I should have been grateful for the distraction-I actually stood up and said to the offender, "Are you kidding me?" I like to think the rest of the audience applauded, but I couldn't hear anything over the hate-blood pounding in my ears.)

Concert goers, Broadway aficionados, film buffs, and many more would not need to worry about such rudeness if theaters utilized jammers that kicked in the second the lights dim. Sure, there's always emergencies, or doctors on call, or parents who must be sure the baby-sitter can reach them, etc. But those people should find a different way to spend their night out.

 

Any car equipped with electronic locks is at risk from signal jammers.

There has been an appeal for South Africans to help identify the person seen in the video about the signal jammer and how it works.

The video was shared widely on social media and quickly went viral.

It is unclear who this person is, but Crime in SA on Twitter plagiarized a post from the South African Police Service (SAPS) and appealed to South Africans to come forward with information about the person.

 

"Unidentified individuals are showing off signal jammers on social media. These devices are used by criminals to block tracking devices and cell phone signals. Let's help police identify this person of interest."

While some comments on the post claim possessing the device is not a crime, crimes in South Australia suggest otherwise.

"Some people are saying that this man cannot be arrested because he has such a device, let us put their doubts to rest. Failure to provide satisfactory service under section 82 of Act 129 of the Third Amendment Act 1993 reports of possession of equipment or items.

"Any person who is in possession of a device or article which is reasonably suspected to have been used or intended to be used to break into or unlawfully enter a motor vehicle, but who is unable to do so; any person who can satisfactorily prove that possession of such device or article , that is, committing a criminal offence," he tweeted.

How signal jammers work

Any vehicle with electronic locks carries the risk of signal interference.

Since signal cell phone blocker are widely available on the Internet, this gadget prevents telematics devices from transmitting their location to vehicle tracking service providers.

Criminals buy illegal GSM and gps jamming devices on the black market and then use them to hijack vehicles and trucks.

These devices can be small handheld devices or large industrial jamming devices the size of a briefcase.

Most jamming devices simply plug into a vehicle's cigarette lighter to block all tracking signals.

"This results in the control center losing contact with the vehicle. The vehicle tracking system only shows the vehicle's last position before the signal was lost.

"Many different types of devices are susceptible to signal interference, including smartphones, remote controls and tracking devices.

"The signals these jamming devices emit on the GSM or GPS frequencies prevent tracking devices in the vehicle from receiving and transmitting messages, thereby blocking the positioning signal.

"The tracking device may be disabled without the driver even being aware".

Four Ways to Prevent Long Range or Signal Interference

1. Physically check that your vehicle is locked, even if you locked it with the remote control.


2. Keep valuables out of sight and, if possible, in the trunk of your vehicle.


3. Please put away your valuables before parking. Put them in the trunk before you start your journey rather than putting them in the suitcase when you arrive at your destination where someone may be watching.


4. If you are unable to lock your vehicle for any reason, move to another location.

A signal jammer is a device that suppresses, interferes with or blocks radio frequencies, the use of which is generally illegal under the Communications Act 1934. This is primarily due to their ability to interfere with critical communications such as emergency communications, disrupt first responder communications, or interfere with maritime or aviation communications.

Under the law, it is unlawful for any person to "willfully or maliciously interfere with or disrupt the radio communications of any station licensed or authorized under this chapter or operated by the United States Government." Additionally, the bill prohibits the manufacture, importation, sale, offer for sale, transportation, or use of equipment that does not comply with the provisions of the bill.

Therefore, it is often impossible to authenticate or use jamming device because their real purpose is to disrupt the communications of authorized devices. Therefore, these devices do not comply with FCC standards and are illegal for use in the United States with few exceptions.

In this case, the FFC received an outage complaint from a telecommunications provider. In response, the agency's law enforcement division launched an investigation into the possible use of wifi signal jammer at a warehouse in Texas. The business owner admitted using such devices to prevent employees from using mobile phones in the workplace.

The company's owners said a telecommunications provider had previously warned their son that such devices were illegal, the FCC reported. Additionally, the owner of the device claimed that he had disposed of the device and would not retrieve it for agents or determine where it went. However, the owner reportedly offered to sell the unit to a broker, who rejected the offer.

The FCC Bureau of Enforcement has since issued $22,000 in fines, including $10,000 for operating an unauthorized device, $7,000 for interfering with authorized communications, and $5,000 for misconduct. The storage company appealed the decision, and in response, the FCC has now upheld the fine.

A Seffner man fined $48,000 by FCC for using cell phone jammer during daily commute

A Seffner man faced a $48,000 fine from the Federal Communications Commission Wednesday for using a cell phone jamming device during his daily commute to and from Tampa.

The FCC alleges that Jason R. Humphreys unlawfully interfered with cellphone service and police communications along Interstate 4 for two years.

"This case highlights the threat to public safety posed by the use of a single signal jamming device that could disrupt all wireless and public communications in the area," FCC Enforcement Bureau Director Travis LeBlanc said in a statement. Communications." Secure Communications. "

In 2013, MetroPCS contacted the FCC saying its cell towers were experiencing interference between Seffna and Tampa in the morning and evening. Police monitored the route and determined Humphrey's sport utility vehicle was the source.

Hillsborough County Sheriff's deputies stopped Humphries and discovered that as they approached Humphries' car, their communications with the police dispatch center were lost. They found a cell phone jammer behind his passenger seat cover.

Hillsborough County employee Humphreys told authorities he has been using it for nearly two years to stop people from talking on the phone while driving.

The FCC proposed a $48,000 fine and gave Humphreys 30 days to respond, including paying in full, requesting payment in installments, or requesting a reduction or cancellation. The FCC said on Monday it had not yet responded and would now "identify and implement" the penalties.

The use or sale of mini gps jammer is against federal law. Jammers block radio communications by preventing devices such as cell phones from establishing and maintaining connections. They can also impact communications for first responders, police and other law enforcement agencies, as well as Wi-Fi and GPS devices, according to the FCC.

As drones rise, so does counter-drone technology. While a variety of potential counter-drone solutions exist, including surveillance equipment such as radars, radio frequency analyzers, or acoustic and optical sensors, as well as high-power microwave (HPM) equipment, drone networks, and lasers, there is another Solutions have been a hot topic for a recent problem in the drone industry: drone GPS interference.

Many drones rely on GPS (and other technologies like ships and cargo fleets, and even smartphones) for navigation and tracking. But some bad actors are trying to jam these GPS signals.

InfiniDome is an Israeli GPS security company founded in 2016 that makes a variety of products, but its focus area is building GPS signal protection systems. This summer, Infinidome published a white paper that clarified how drone gps jamming works and provided a very sobering demonstration of how GPS (GNSS) systems are vulnerable to jamming attacks.

Why does drone interference occur?

Why is it a problem?

There are many reasons why people would want to jam drone GPS signals, including defense applications, causing enemy drones to get lost or crash. While drones are used in systems such as aerial surveillance to catch drug traffickers, these drug cartel criminals are known to use drone jammers to prevent this from happening. In fact, Mexico reports that jammers were used in 85 percent of all recorded cargo truck thefts, according to the Resilient Navigation and Timing Foundation, a science and education nonprofit in Virginia.

This isn't just big military or serious legal use cases. A drone light show over a shopping mall in Zhengzhou, China, went awry when a drone fell from the sky, endangering 5,000 onlookers, after a drone jammer was used.

In short, even if you don't necessarily think there's a clear enemy trying to take down your drone, it's crucial to be prepared for a GPS jammer attack on your drone. This happens with drone light shows too.

Drone interference may not be all bad

This is not to say that all drone interference is necessarily bad or evil. In fact, sometimes it may be considered the opposite. For example, the Federal Aviation Administration turned to counter-drone companies to help research drone jammers to ensure that unwanted drones are not flying near airports and posing a safety risk to flights full of passengers. The Department of Defense also uses drones to protect classified areas or other locations that require security.

How does drone GPS jamming actually work?

Drone GPS jammers utilize GNSS receivers, which use GPS signals (along with GLONASS, Galileo and other constellations, hence the name "GNSS" - Global Navigation Satellite System), but it is known that these receivers, whether through deliberate jamming Receivers are all very fragile and susceptible to interference - but often even unintentional interference (like you might experience while driving through a mountain tunnel or even sometimes when you lose cell service in certain parts of your home).

Obtaining jamming equipment is very easy and cheap. You don't need an entire mountain to block GPS signals-you can find GPS-jamming devices online for less than $100. As long as the signal jammers can emit a signal on the same frequency as yours but with a stronger signal, they will win and jam your drone.

Of course, it's not that simple. There are a variety of jamming attacks and signals, including continuous wavelengths, where a single frequency is jammed and anything transmitted on the same frequency will be blocked. With another method called narrowband, the power is spread out and diluted across different frequencies that make up a band (a range of about 2MHz). To carry out an attack, a cell phone jammer "attacks" the bad guys by creating a series of narrowband signals that are transmitted immediately after each other.

Drone interference solution

So while there are various ways to jam a drone GPS signal, there are also various ways to protect your GPS system. The challenge? These solutions can be expensive, heavy and bulky in order to process all those digital signals.

 

As a professional photographer and drone pilot, I've seen firsthand how drone technology has become mainstream (pun intended) in recent years.

But with great power comes great responsibility, and as our skies become increasingly filled with these high-tech devices, the need for regulatory and control measures becomes increasingly clear.

Enter the world of drone jammers.

In this article, we'll explore the ins and outs of drone jammer, from basic functionality to legality. We will also discuss some practical applications of this technology.

Whether you're a drone enthusiast interested in the technology, a security professional looking to learn about drone defenses, or just someone concerned about privacy, this guide is for you.

Introduction to drone defense technology

Okay, guys, let's get down to business. What exactly is a drone jammer? Why should we care?

What is a drone jammer?

• Imagine you are flying your drone and taking stunning aerial shots, and suddenly your drone starts to react. It doesn't respond to your controls and seems to have a mind of its own. My friend, you may have just encountered a drone jammer.


• Simply put, a drone jammer is a device designed to interrupt the control signal of a drone.


• It acts like a drone party killer, ruining the party by emitting electromagnetic noise on certain radio frequencies.


• These frequencies cover the same radio and GPS signals the drone uses to operate, effectively grounding it.

The development of drone technology

Now you might be asking yourself, "Why would anyone want to stop drones?" Well, like any technology, drones can be a double-edged sword. On the one hand, they've revolutionized industries from film production to agriculture, providing a bird's-eye view that was previously only possible via expensive helicopter flights.

On the other hand, they also found a whole lot of mess when it came to privacy and security issues. Imagine a drone hovering outside your window, or worse yet, a drone being used for illegal activity. Not that funny, right?

The need for drone jammers

This is where drone jammers come into play. They're essentially a way to keep drones away from places they're not supposed to go. Think of them as the gatekeepers of the sky, preventing unwanted drones from entering restricted airspace.

But it's not just a matter of privacy and security. Drone jammers also play a vital role in ensuring safety. Because the last thing you want is for a drone to collide with a passenger plane.

How drone jammers work

Picture this: you are attending a rock concert and trying to have a conversation with your friend. But the music is too loud and you can't hear each other. This is essentially how a gsm jammer works.

Drone jammers emit electromagnetic noise at certain radio frequencies, similar to loud music at a concert. This noise drowns out the radio and GPS signals the drones use to operate, effectively drowning them out.

The impact of drone jammers on drones

So what happens when a drone is hit by a jamming signal? Well, it's a bit like getting lost in a strange city without a map.

Most drones respond to jamming signals by returning to their starting point. This is their way of saying: "I'm lost and I'm going home." In some cases, a drone jammer can land a drone at a scene for forensic investigation.

How to jam drone signals

1. Now, before you get any ideas, I want to make one thing clear: jamming drone signals should not be attempted at home. This is a complex process that requires a deep understanding of radio frequencies and drone technology. Plus, it's illegal in a lot of places (but we'll get to that later).


2. However, it is still interesting to understand how this process works. The frequency of drone jammers is generally allocated at 2.4GHz or 5.8GHz. These are public frequencies and are not suitable for manned aircraft, public broadcasting or cell phone signals.


3. The phone jammer projects a signal in the form of a cone, and when the drone is hit by the signal, it typically returns to its origin or lands in place.

Legality of using drone jammers

It's time to talk about the elephant in the room: the legality of drone jammers. As with any technology, there are rules and regulations that govern its use.

Let me tell you: the legal framework for gps blocker is as complicated as the flight path of a drone.

Legal restrictions on drone jammers

First things first, it's important to understand that the use of drone jammers is heavily regulated. In the United States, for instance, the use of a drone jammer is generally prohibited by the Federal Communications Commission (FCC). The reason? Well, it's because jammers interfere with authorized radio communications, which is a big no-no in the eyes of the FCC. Read more here.

But it's not just the U.S. Many other countries also have strict regulations on the use of drone jammers. So, if you're thinking of getting your hands on one, it's crucial to understand the laws in your country.

Consequences Of Illegal Use Of Drone Jammers

Now, you might be wondering, "What happens if I use a drone jammer illegally?" Well, let's just say it's not a path you want to go down.

In the U.S., for example, the penalties for illegal use of a jammer can be severe. We're talking hefty fines, and in some cases, even jail time. So, it's safe to say that using a drone jammer without proper authorization is a risky business.

When used legally and ethically, wifi blocker can play a crucial role in maintaining safety and privacy.

Drone Jamming Techniques

Understanding Drone Jamming And Spoofing

First things first, let's clear up some terminology. You've probably heard the terms "drone jamming" and "drone spoofing" used interchangeably. But they're actually two different techniques.

Drone jamming, as we've discussed, involves disrupting a drone's control signals, effectively grounding it.

Drone spoofing, on the other hand, is a bit more sneaky. It involves sending false information to a drone, tricking it into thinking it's somewhere it's not. It's like giving someone wrong directions to a party.

Techniques For Effective Drone Jamming

Drone jamming can be done in a few different ways, depending on the type of drone and the situation. Here are a few common techniques:

Signal Jamming: This is the most common technique, and it involves sending out a stronger signal to override the drone's control signals.

GPS Spoofing: This involves sending false GPS signals to the drone, tricking it into thinking it's in a different location.

RFID Tagging: This involves attaching a small device to the drone that emits a signal, allowing the drone to be tracked and jammed.

Remember, these techniques should only be used by authorized personnel and in accordance with local laws and regulations.

Real-World Applications Of Drone Jammers

Use Of Drone Jammers In Military And Security Operations

First up, the big leagues: the military. In the world of defense and security, jammers are a crucial tool. They're used to protect sensitive areas from unwanted drone activity, whether it's a military base, a government building, or a critical infrastructure site.

For instance, during military operations, drone jammers can be used to prevent enemy drones from gathering intelligence. They can also be used to protect convoys from drone attacks. It's like having a high-tech shield that keeps the skies clear of unwanted drones.

Use Of Drone Jammers In High-Profile Events

But it's not just the military that uses jammers. They're also used to protect high-profile events, like the Super Bowl or the Olympics.

Imagine you're at the Super Bowl, enjoying the game, when suddenly a drone flies overhead. Not only is it a nuisance, but it could also be a security threat. That's where drone jammers come in. They can be used to create a "no-fly zone" over the event, ensuring that the only thing flying is the football.

So, whether it's a military operation or a high-profile event, drone jammers play a crucial role in maintaining safety and security.

Up next, we'll take a look at the future of drone jammers. Stay tuned!

The Future Of Drone Jammers

Alright, folks, we've reached the final leg of our journey: the future of drone jammers. As with any technology, drone jammers are constantly evolving. So, let's take a peek into the crystal ball and see what the future might hold.

Advancements In Drone Jamming Technology

First up, the technology itself. As drones become more advanced, so too do the techniques to jam them. We're seeing the development of more sophisticated jammers that can target specific drones, disrupt multiple frequencies at once, and even take control of rogue drones. It's like a high-tech game of cat and mouse, and it's fascinating to watch.

The Rise Of Anti-Drone Technology

But it's not just about jamming drones. We're also seeing the rise of anti-drone technology. This includes things like drone detection systems, drone shields, and even drone-hunting eagles (yes, you read that right!).

The goal of these technologies is not just to disrupt drones, but to detect and neutralize them before they become a threat. It's a proactive approach to drone security, and it's an exciting area of development.

The Legal Landscape Of Drone Jammers

Finally, there's the legal landscape. As drone technology evolves, so too do the laws and regulations that govern it. We're likely to see more clarity and guidance on the use of drone jammers in the coming years, which will be crucial for individuals and organizations looking to use this technology responsibly.

Conclusion: The Sky's The Limit

We've reached the end of our journey through the world of jammers. We've covered a lot of ground, from the basics of jammers to their legality, how to choose one, jamming techniques, real-world applications, and even a glimpse into the future.

Remember, drone jammers are powerful tools, but they should be used responsibly. Always respect the privacy and safety of others, and make sure you're familiar with the laws and regulations in your area before using a jammer.

Frequently Asked Questions (FAQs)

As we wrap up our journey through the world of drone jammers, I thought it would be helpful to address some of the most common questions I've heard from folks like you. So, let's dive into the FAQs!

Are Drone Jammers Legal?

The legality of jammers varies from country to country, and even within different regions of the same country. In many places, the use of drone jammers is restricted to military, law enforcement, and other authorized entities. Always check your local laws and regulations before using a drone jammer.

Can I Build My Own Drone Jammer?

Technically, yes, you could build your own jammer. There are even tutorials online that show you how. However, I would strongly advise against it. Not only is it likely illegal, but it could also be dangerous. It's always best to leave this kind of thing to the professionals.

How Far Can A Jammer Reach?

The range of a drone jammer depends on the specific model and the environment in which it's used. Some jammers can reach drones up to several kilometers away, while others have a more limited range. Always check the specifications of the jammer before using it.

Can A Drone Jammer Take Down Any Drone?

Not necessarily. Different drones operate on different frequencies, and some drones have anti-jamming features. A jammer needs to be able to disrupt the specific frequencies used by the drone in order to be effective.

 

The purpose of these homemade devices was to jam the signals from kamikaze drones, but the radio transmissions protecting the tanks could also reveal the tank's location.

Russia's Lancet kamikaze drones, designed to locate targets and then crash, have become a serious problem for the Ukrainian military.

Drones buzz over the battlefield, flown by pilots on the ground and guided by radio signals.

Jammers mounted on tanks or other vehicles can interfere with the signal and cause the drone to miss its target.

Russia's invasion of Ukraine has intensified the drone arms race, with both sides using increasingly sophisticated drones for a variety of missions. The latest salvo is a repeating jammer that forms an invisible protective dome over the tank and jams the signals of any kamikaze drones trying to attack it.

Kamikaze Drone

The Lancet was made by Kalashnikov...yes, that Kalashnikov

One of the most dangerous types of drones on the Ukrainian battlefield is the kamikaze drone, which is designed for one-way flight and is launched over the battlefield. The pilot sits on the ground at the control station and must rely on the drone's camera to locate the target. When he does so, he flies a drone to attack the target and detonates explosives and sometimes anti-tank charges.

Russian "Lancet" drones pose a serious threat to Ukrainian troops searching for tank and artillery targets in the open air. The new signal jammers, first reported by Ukrainian defense blog Militarnyi, is a radio device operating in the 900 MHz band and transmitting 50 watts of power. When a kamikaze drone falls from the sky in a suicide attempt, the jammer interrupts the signal, causing the drone operator to lose control and miss.

The explosives carried by the Lancet drone can penetrate 200 millimeters of armor; this is enough to penetrate the thin upper armor of many tanks and even the turret. Most Ukrainian tanks have reactive armor tiles on their roofs designed to weaken the plasma jet of shaped charges, but Ukrainian artillery has no such protection. As a result, there are multiple videos on social media showing the Lancet targeting Ukrainian field artillery.

 

Jammer in Box

Without jammers, Ukrainian tanks can only hide under camouflage nets. Tree cover also prevents kamikaze drone operators from noticing tanks and other equipment

The cell phone jammer is mounted on top of the tank's turret, behind the commander's hatch at the highest point of the tank. The electronic equipment is encased in a waterproof casing and then enclosed in a sealed metal box to protect it from enemy fire. The antenna sticks out of the box and sends an interfering signal.

It's unclear whether the gps jammer runs on batteries or is connected to the tank itself, but the 50-watt power consumption and the fact that the box is just centimeters from the open tank hatch suggests that cables from the tank's electrical system are exiting. Although this requires the hatch to be open while the jammer is firing, the crew will mostly use it when the tank is stationary. Ukrainian tanks keep their hatches closed under their armor during combat, and moving tanks are generally harder to hit.

The 900 MHz band the jammer emits is a common band used by long-range civilian drones. It is also the same wavelength that the Lancet drone operates on. It is understood that the Russian military also uses civilian drones as reconnaissance systems and purchases them in large quantities on the global market.

Wireless jammers have some disadvantages. The 900 MHz band is also commonly used for voice communications, so all vehicle transmissions must use a different band or else be cut off by other devices. This can result in a loss of combat coordination between jammer-equipped vehicles. The signal can also interfere with friendly drones and reduce troops' situational awareness.

Another problem is that the drone jammer itself emits a 50-watt radio signal announcing the presence of the tank to anyone capable of listening. If an enemy force could detect and locate jammers, it could actually count the number of tanks and other combat vehicles deploying jammers and learn their locations.

Despite these disadvantages, using a disruptor is better than blasting from above with shaped charges. But the advent of radio-controlled drones means military commanders now have to know when to mask and reveal their electromagnetic signatures. Has the enemy turned on their own jammers? If so, they may not be using drones, but they may be moving and preparing to attack.

 

 

"The U.S. military has invested a lot of work over the past decade to improve the security of GPS," said James Lewis, a technology expert at the Center for Strategic and International Studies, a Washington think tank.

Lewis said Russia has deployed "powerful" jammers in Syria since 2015, disrupting much of the electromagnetic spectrum. These phone jammer are powerful enough to disrupt aircraft landing in Tel Aviv, Israel.

"The problem with these large, powerful jammers is that they are vulnerable," Lewis told Mission & Purpose. "It sends a strong signal, 'I'm here.' Target me." That's attractive when you don't have to worry about someone fighting back. I think that's one of the reasons it's used in Syria. "

Russia also has more advanced jammers that can jam certain frequencies, Lewis said, and they have invested time and effort in developing the ability to spoof GPS signals and throw navigation systems off course. To this end, the Chinese military, whose electronic warfare capabilities lag behind Russia's, is purchasing Russian-made jammer device.

The United States also helped Ukraine find and destroy Russian jammers, a "high priority" mission, according to a secret Pentagon document that was part of a secret document allegedly leaked by pilot Jack Teixeira .

"We will continue to advocate/recommend disrupting/destroying these jammers wherever possible," the document said.

Criminal gang uses GPS jammer to steal cars

Criminal gangs are importing GPS jammers from China to steal expensive cars or car transporters carrying valuable cargo. However, they believe that a terrible accident will soon happen to the gang.

Tracking devices have become an important part of vehicle safety, often using GPS. However, GPS systems are susceptible to a technique called "jamming," which blocks the signal between GPS satellites and their receivers.

Introducing a more advanced tracking device that combines GSM, GPS and VHF technology in one device. The result is a solution that is more resilient to criminals using jamming devices. All 52 police forces in the UK use a stolen vehicle tracking and recovery system, which tells police the original location of a stolen vehicle.

Many people don't realize how dependent our lives are on GPS. It's not just car owners who face growing risks of disruption. "With criminals increasingly importing jammers from China or manufacturing their own in the UK, air traffic control or other critical networks could be vulnerable to terrorist attacks if countermeasures are not taken."

People are overly reliant on GPS as a safety and recovery system, especially when used alone. As more and more U.S. motorists become vulnerable to jamming devices, we believe no one technology is strong enough.

 

We are convinced that this was an act of pure, unadulterated charity, uninfluenced by self-interest. Cellphone jammer maker CellAntenna Corp. is calling on U.S. lawmakers to change federal law to allow law enforcement officers to use cellphone jammers more broadly. We bet you can guess why too - and yes, it's helpful in the fight against terrorism. Because as we all know, there are a lot of cell phone terrorists out there (in fact, for us, anyone we see with a cell phone is automatically suspect). CellAntenna said in a statement that adding cell phone jamming is "the first step in increasing profits to prevent IED attacks in the United States." How refreshing - a company with a social conscience.

The company is challenging FCC rules on cell phone jamming devices

A small Florida company is asking the Federal Communications Commission to change a rule that bans the sale of cell phone signal encryption equipment to local and state governments.

CellAntenna filed a lawsuit in the U.S. Court of Appeals for the Eleventh Circuit in Atlanta on Nov. 22 challenging the Communications Act of 1934, which is enforced by the FCC. The 1934 Act and related FCC regulations prohibit the use of cellular and radio frequency jamming devices except by federal agencies. That means local and state officials are prohibited from using such devices, which could be used to prevent terrorist attacks.

CellAntenna contends that the Communications Act and the FCC's interpretation of the law's provisions are unconstitutional because they conflict with the Homeland Security Act of 2002, which Congress passed in the aftermath of the September 11, 2001, terrorist attacks.

It is well known in intelligence and law enforcement circles that cell phones can be used to remotely detonate certain types of bombs. The electrical properties of most batteries used in today's cell phones provide enough energy to produce the necessary spark or energy to ignite detonators or modified electric matches typically used for plastic explosives. In addition, even low-end mobile phones can use built-in alarm and timing mechanisms, and even the simplest and cheapest mobile devices can be used as bomb detonation tools.

Mobile phones are believed to have been used in the 2004 Madrid train bombings. Insurgents have used them effectively to trigger street bombings in Iraq in recent years. U.S. troops in Iraq are using devices made by companies like CellAntenna that jam or block cellphone signals to protect convoys traveling through known trouble spots.

But in the United States, only federal agencies are allowed to use phone encryption devices. The law prohibits local and state law enforcement agencies from obtaining such devices as first responders to domestic terrorist attacks.

"It simply doesn't make sense that the FBI can use these devices but local and state governments, which are considered an important part of counterterrorism under the Homeland Security Act, cannot," said Howard Melamed, CEO of CellAntenna. That makes sense." "We provide weapons and other equipment to local police to protect the public, but we can't trust them to have cell phone wifi jammers devices? It doesn't make sense."

This point is a key element of CellAntenna's case against the FCC

"Whereas the FCC prohibits the sale of radio frequency and cellular jammers to state and local police departments, the Homeland Security Act consistently and repeatedly directs the Department of Homeland Security to take whatever measures are necessary to empower local law enforcement agencies and first responders in the fight against global terrorism."

 

The DroneGun interferes with robotic aircraft at a very safe distance

There are a number of systems that can be used to shoot down wayward or dangerous drones, but they tend to have one big problem: You need to be relatively close to the drone, which can be scary if the robotic plane is packing explosives. DroneGun, a jammer gps that disables drone signals (including GPS and GLONASS positioning) from up to 1.2 miles away. Like most of its competitors, it doesn't destroy the target drone - it simply forces the vehicle to land or return to its starting point. Counter-drone teams can not only eliminate threats from a safe distance, but also locate their pilots.

It's not the lightest machine, but it's portable enough for one person to use. You also don't need technical training, so it's easy for security personnel to use.

Whether you see DroneGun running or not is another matter. It's not yet FCC certified, so you can't legally operate it in the United States unless you work for the government. If approved, though, it could help shoot down drones at airports, protect soldiers from drone bombs and help in situations where they simply can't get close.

Drones can use anti-laser jammers to protect themselves

There have been many efforts to build lasers that destroy drones. But how to protect these drones? Adsys Controls thinks it can help. It's making Helios, a passive jammer that confuses laser weapons. If it detects an incoming laser beam, it detects the characteristics of that beam (such as its pulse and wavelength) and interferes with it to prevent the laser from locking on and baking the drone. The company did not specify how the jamming works, although it could be an anti-laser. The only certainty is that it's reliable - it's "permanent protection" against subsequent lock attempts, not just a brief interruption.

You may have to wait a while to see Helios in action, as there is currently no mention of a contract. Moreover, it is uncertain how effective it will be. Can a laser be aimed at part of a drone without being caught by a jammer? Is the system fast enough to stop the highest power laser from burning up the drone in seconds? Still, drones do not yet have true anti-laser defense capabilities. Any protection is bound to help, and if Adsys' solution lives up to its hype, it could be very effective.

The FCC is pursuing cell phone jammer that could leave users in the lurch

The Federal Communications Commission (FCC) has put a bounty on the head of any vigilante who hates cell phones. These GPS and signal jammers are especially popular in theaters, quiet restaurants and many school systems that struggle with sexting in the classroom. The FCC is calling on people to stop using the devices and report them to neighbors because they pose a serious health and safety risk by interfering with 911 calls and other emergencies nearby. Therefore, if you recognize a so-called "jammer," don't hesitate to file a complaint with the FCC, information can be found in the source link below.

 

 

Twenty years after the worst attack to ever occur on U.S. soil, it's not just large, populated passenger planes that keep officials and experts up at night, but also the threat of smaller, readily available unmanned aerial systems capable of carrying deadly payloads through the skies of an unsuspecting nation.

Drones are not tomorrow's weapons of mass destruction. They're here today, and the technology required to fashion such a device is only getting cheaper, smarter and more accessible.

One U.S. military official who requested anonymity paints a potential nightmare scenario involving small drones, referred to as unmanned aerial systems, unmanned aircraft systems, or simply, UAS.

"I kind of wonder what could you do if you had a couple of small UAS and you flew into a crowded stadium," the U.S. military official told Newsweek. "That could cause a lot of damage and it's a scenario that could potentially be in play."

While "no specific knowledge" of an active threat was discussed, the U.S. military official said that "there is concern given the proliferation of small, portable drones, that explosive drones could cause a mass casualty event."

It wouldn't be the first time the nation had been caught off guard by a possible danger looming right in front of authorities.

"It's just like I had no specific knowledge before 9/11 that people could hijack planes and crash into buildings, but Tom Clancy wrote a book about it," the U.S. military official said.

When the political thriller "Debt of Honor" was released in 1994 depicting a hijacked airliner targeting the U.S. Capitol, the concept of an aerial suicide raid had largely been confined in the national consciousness to the experience of Japanese kamikaze pilots in World War II. It wasn't until nearly 3,000 were killed on September 11, 2001 that what had been an eventuality became a reality.

But when it comes to UAS, the age of tactical drone warfare is already upon us. Shortly after 9/11, the United States became the first country to truly weaponize drones, fitting them with precision missiles that became a staple of the "War on Terror."

In the years since, drones have evolved from a high-end military technology to a commercial hobby flown by enthusiasts across the globe and sold by a multitude of companies on the civilian market. With the explosion of this seemingly innocent innovation has come a rise in nefarious usage that the U.S. military official with whom Newsweek spoke described as "an emergent threat" already demonstrated in several high-profile events.

One such event came just last weekend when three explosive-laden UAS, believed to be simple quadcopter models, targeted the residence of Iraqi Prime Minister Mustafa al-Kadhimi in an assassination attempt. Kadhimi lived, but photos released of his home revealed the destructive capabilities of such devices.

Kadhimi was not the first world leader to be preyed upon by bomb-rigged UAS. In August 2018, two drones carrying explosives detonated in an apparent failed attempt to take out Venezuelan President Nicolás Maduro during a military parade in Caracas. He also escaped with his life.

Prior to these incidents, militants and militias had already managed to utilize such technology, giving non-state actors a sort of rudimentary yet deadly air force to take on better-equipped foes. In Iraq and Syria, U.S. troops have been targeted from above by both the Islamic State militant group (ISIS) and Iran-aligned paramilitary forces.

Even more destructive platforms have seen action on the battlefield in the form of what's known as loitering munitions, or suicide drones. Last year, Azerbaijani forces demonstrated a deadly edge over Armenian rivals during a brief but bloody war over the disputed Nagorno-Karabakh territory through their use.

"They're relatively small, inexpensive drones, but they kind of cross that boundary between a drone and guided missile," the U.S. military official said.

This point was echoed by a security official from Israel, a country that produced some of the loitering munitions employed by Azerbaijani forces with substantial effect and now prove a potential concern for Iran as tensions simmer between the neighbors.

"This tool today is so easy, and small drones, you just really order them in and you've got yourself like a guided precision missile," the Israeli security official told Newsweek.

The Israeli security official noted that even with their current destructive potential, the munitions attached to such UAS today are in their relative infancy, not yet on a scale that any one of them alone could replicate a 9/11-style attack.

But their potential is already rapidly growing

"They are becoming much more accurate in their capabilities of navigation," the Israeli security official said. "I think where we will be seeing things is that the amount of explosives will get bigger now."

Smaller commercial UAS have another unique advantage over traditional aircraft and missile platforms: They have no launch signature, making them far more difficult to detect. Used in greater numbers, known as a swarm, they're also harder to intercept.

"If you need to intercept a dozen, an F-16 payload, if it's only doing air-to-air would be about six different air-to-air missiles, or similar to an F-35," the Israeli security official said. "So that already means that you need a few airplanes, and you need the time if you're looking at interception."

Israel was among the first nations to refine wartime drone technology, and it continues to field various platforms for covert missions. But its rivals have also demonstrated an early prowess for such technology, as proven by the Lebanese Hezbollah, the Palestinian Hamas, and their supporter, Iran.

Iran has developed an extensive arsenal of drones, including suicide drones capable of flying beyond 2,000 kilometers, exceeding 1,240 miles. Israel and the U.S. have both accused Iran of directly supplying UAS technology to partnered militias across the region, an allegation denied by the Islamic Republic.

"I think Tehran has its own independent defense program based on its defense needs and can define its efforts to counter the threats by strengthening its defense capabilities," an Iranian official told Newsweek.

China has also excelled in UAS technology, and Russia has developed high-end systems of its own as well.

The Israeli security official noted another trend that could prove deeply problematic to the safety of the region and beyond, a trend linked to Israel's ally, the U.S., and the withdrawal from a 20-year war in Afghanistan, where ISIS has sought to stage a comeback in a country the U.S. first entered in response to 9/11.

"We see another rise of terror, and I'll say, being both humble and appreciative to the U.S., but after Afghanistan, we do see a rise in what potentially could come again with the terror activities and the kind of backing that some of the terror organizations feel stronger and maybe even more courageous," the Israeli security official said. "This tool of drones can definitely be something that we might be seeing more."

One man who has written and spoken extensively on the potential impact of drones in the wrong hands is Zachary Kallenborn.

Kallenborn is a policy fellow at George Mason University's Schar School of Policy and Government and a research affiliate with the University of Maryland's Unconventional Weapons and Technology Division of the National Consortium for the Study of Terrorism and Responses to Terrorism. He has also served as a national security consultant and contributed to the U.S. Army as part of its Mad Scientist Laboratory.

"Drones are definitely capable of causing mass casualties," Kallenborn told Newsweek.

Echoing the example put forth by the U.S. military official with whom Newsweek spoke, he imagines a crowded event as a potential target.

"Growing drone technology also increasingly allows drones to be flown autonomously or in collaborative swarms," Kallenborn said. "That increases the damage potential significantly. Imagine a terrorist air raid: a group of drones dropping bombs on a concert or stadium crowd."

Even more damaging, attackers could vastly multiply casualties by employing weapons of mass destruction, Kallenborn warned.

"Drones would be highly effective delivery systems for chemical, biological, radiological, and nuclear weapons," he said. "Drones could, say, spray the agent right over a crowded area."

Kallenborn said he was "also quite concerned about drone attacks on airplanes, because aircraft engines and wings are not designed to survive drone strikes."

But he notes that "who the attacker is matters a lot," adding that "a big limiter" for the worst-case scenarios "is the ability of terrorists to acquire the chemical, biological, radiological, or nuclear agent, which they have historically struggled with."

He pointed out the difficulty of a militant group acquiring both the material and manpower to fly a larger swarm-sized fleet while avoiding detection.

"But that limitation is not an issue for state militaries," Kallenborn said. "Militaries have the resources and technology to make truly massive swarms that could rival the harm of traditional weapons of mass destruction, including small nuclear weapons."

"Not only is such a weapon massively powerful, it would be quite difficult to control," he added. "If you have 1,000 drones working together without human control, that's 1,000 opportunities for failure. And even more, because in a true drone swarm, the drones talk. As we've seen with COVID vaccine paranoia, misinformation can spread easily even among beings far smarter than an algorithm-guided drone."

As humans and machines are wont to err, so are defenses, and drones add a new level of difficulty in their ability to conduct random, difficult-to-detect operations. The U.S. military official with whom Newsweek spoke expressed a level of skepticism regarding existing defenses being acquired by the Department of Defense.

"The DOD is pouring a lot of money and effort into counter-UAS technology, but I think the DOD's PR exceeds the actual capability of these devices," the U.S. military official said.

One of the agencies keeping an eye out for UAS and drone activity on the domestic side is the Federal Aviation Authority. An FAA spokesperson told Newsweek that "the FAA is tasked with ensuring the safety of the National Airspace System (NAS) as well as people and property on the ground."

"When criminal activity is suspected, we work with our federal, state, and local law enforcement partners by providing them assistance with their investigations and prosecutions," the spokesperson said.

One way in which the FAA is seeking to improve the ability for authorities to determine potential problems posed by UAS is by enforcing remote identification, through which drones would be required to provide key information such as identity, altitude and current location as well as the location of its operator and take-off point.

"Remote identification requirements for all UAS operators, when combined with our current registration requirement, will enable more effective detection and identification," the FAA spokesperson said. "This will also help law enforcement to connect an unauthorized drone with its operator. Remote identification will help law enforcement determine if a drone poses an actual threat that needs to be mitigated, or if it's an errant drone that got away from someone but means no harm."

The rise of the drone threat has given birth to a booming new industry of counter-drone technologies. Among the leading companies in this field is DroneShield, an Australian firm that has supplied cutting-edge tools to the likes of the NATO military alliance and the United Nations.

DroneShield CEO Oleg Vornik shared Kallenborn's concerns about WMD-strapped UAS in large numbers.

"Small UAS can be seen as a highly effective and cheap platform for surveillance and payload delivery," Vornik told Newsweek. "For payload delivery, a small UAS can easily carry up to a few pounds of weight - this is a lot of explosive or biological or chemical weapons."

"What's more," he added, "at $1,000-$2,000 per UAS, and swarming technologies available today (think of giant figures in the sky or fireworks, all generated by choreographed drones), this can be easily in 100s of drones, each carrying a dangerous substance."

These figures may seem high, but Vornik argued that the general lack of oversight would make it hard to track acquisition. And even if suggested controls were put in place, he said, the threat would only partially be addressed.

"UAS can be purchased today in a completely unrestricted way, being considered toys, essentially. Registration would solve some of the issue, but consider how many unregistered firearms get used for terrorism," Vornik said. "The pilot of the drone would also be invisible/difficult to catch in an attack, making it more appealing to use"

In addition to the kinetic threat, he warned of potential cyber attacks employing UAS

"Call it a conspiracy, but we received reports that the Ever Given container ship (yes, the one that blocked Suez Canal and stopped much of sea traffic) was due to a cyber hacking from a drone, when a request for ransom was denied," Vornik said. "We are now hearing of this commonly from ship customers, especially in areas close to the better-known rogue states."

Last week, DroneShield released the 6th edition of its C-UAS, or counter-UAS, factbook, which details the scope of potential threats posed by small drones.

The guide covers recent events in drone warfare, including the Nagorno-Karabakh conflict and the 2019 attacks on Saudi Aramco oil sites, claimed by Yemen's Ansar Allah, or Houthi, movement but blamed by Saudi Arabia and the U.S. on Iran. It also gives examples of the latest innovations by China and Russia, and identifies some of the most popular heavy-lifting UAS that could be used even more discretely than their larger cousins.

The report provides potential solutions as well, including a range of detection capabilities such as radio frequency, radar, acoustic, optics and multi-sensor systems. It also lists neutralizing assets including drone radio frequency jammer, GPS jammers, cyber tactics, directed energy attacks, counter-UAS drones and kinetic systems capable of blasting UAS out of the sky.

"Without dedicated C-UAS system (for detection and defeat of such UAS)," Vornik said, "there would be no warning and no time to react, until it is too late and the damage is done."

As to whether such tools and methods would be employed before the next attack, he has expressed a note of skepticism.

"We live in a reactive society," Vornik said. "Boulders across the pathways have only started to be placed after terrorists used vehicles to bulldoze through crowds, as an example."

He warned that governments and their law enforcement and security agencies must start setting up systems now to defend against UAS attacks.

"We need to be more proactive in setting up UAS detection and defeat systems across areas where large gatherings of people are likely, the high profile places, sort of areas which would be terror sweet spots," Vornik said. "Law enforcement and homeland security personnel need to be trained for this threat, much like more conventional attacks."

 

As drones rise, so does counter-drone technology. While there are a variety of potential drone defense solutions, including surveillance equipment such as radars, radio frequency analyzers, or acoustic and optical sensors, as well as high-power microwave devices (HPMs), drone networks, and lasers, there is another Solution A hot topic in the drone industry recently: drones interfering with GPS.

Many drones (as well as other technologies such as transportation and freight fleets, and even smartphones) rely on GPS for navigation and tracking. But some criminals are trying to jam these GPS signals.

InfiniDome is an Israeli GPS security company founded in 2016 that produces a variety of products, but its main focus is on developing GPS signal protection systems. This summer, Infinidome published a white paper that clarified how drone gps jamming works and provided a very sobering demonstration of how vulnerable GPS systems (GNSS) are to jamming attacks.

You can download and read infiDome's full GPS interference white paper here. I use it to give a quick overview of the most important things you should know about drone GPS interference. Here are the reasons why people try to jam drone GPS signals, how to jam them, and what to do about them.

Why does drone interference occur and why is it a problem?

There are many reasons why people would want to jam a drone's GPS signal, including defense applications to prevent enemy drones from getting lost or crashing. While drones are used in systems such as aerial surveillance to catch drug traffickers, drug cartel criminals use drone jammers to prevent this from happening. In fact, Mexico reports that jamming was used in 85 percent of all recorded truck thefts, according to the Resilient Navigation and Timing Foundation, a science and education nonprofit based in Virginia. device. The foundation aims to protect critical infrastructure through technologies such as InfiniDome.

This isn't just about large military or serious legal use cases. A drone light show over a shopping mall in Zhengzhou, China, fell from the sky after someone used a drone jammer, putting 5,000 spectators at risk.

In short, even if you don't necessarily believe there is an obvious enemy trying to destroy your drone, it's crucial to be prepared for a drone GPS jammer attack. This also happens with drone light shows.

Jamming drone may not be all bad

This is not to say that all drone interference is necessarily bad or evil. In fact, it may sometimes be considered the opposite. The Federal Aviation Administration, for example, turned to counter-drone company Dedrone to help work on drone jammers to ensure unwanted drones aren't flying near airports and posing a safety risk to flights full of passengers. The Department of Defense also uses drones to protect secret areas or other locations that require security. InfiniDome created a video about drone interference (which also serves as an ad for their product), which you can watch here:

How does drone GPS jamming actually work?

So how does drone GPS jamming actually work?

The GNSS receiver used by the drone GPS jammer uses GPS signals (along with GLONASS, Galileo and other constellations - hence the name "GNSS" - Global Navigation Satellite System), but is known to be vulnerable to attack and easily jammed regardless of There is intentional interference - but often even unintentional interference occurs (like you may have experienced while driving through a tunnel in a mountain, or sometimes even in certain areas of your home where cell phone blocker reception is interrupted).

Purchasing jamming equipment is easy and cheap. You don't need an entire mountain to block GPS signals-you can find GPS jamming device online for less than $100. As long as the jammer is able to emit a stronger signal on the same frequency as yours, it will gain the upper hand and jam your drone.

Of course, it's not that simple. There are all sorts of jamming attacks and signals, including Continuous Wavelength, where a single frequency is jammed and anything transmitted in that same frequency will be blocked. And with another method called narrow band, power is spread and diluted throughout the different frequencies making up a band (a range of around 2MHz). To attack, jammers "barrage" the bad by creating a series of narrow-band signals that transmit shortly one after each other.

 

WashingtonCNN - Russia has been hindering US-created mobile rockets more frequently in Ukraine recently, using electronic jammers to overthrow its GPS-based targeting system, this causes rockets to misfire their targets, multiple people who were involved with the project told CNN.

Ukrainian military officials have had to invent multiple different solutions to the problem of their own equipment, with the American help, they have employed the High Mobility Artillery Rocket System (HIMARS) as the most celebrated and feared piece of military hardware in Ukraine's conflict.

The medium-range rocket systems were touted as a significant game changer in the conflict, and have had a significant role in the past year since their arrival in Ukraine last summer, including in the offensive that led to the takeover of territory that was significant to Ukraine last year.

However, recent months have seen the systems become increasingly less effective as a result of the Russians' increasing blocking, five American, British and Ukrainian sources tell CNN that the HIMARS have been modified to counter the Russians' increasing jammer device.

It's a constant pursuit of a solution to the cell phone jamming, a Pentagon official said, only for the Russians to then reverse the solution. And it's not clear how long-term the game is sustainable.

With a large-scale Ukrainian offensive expected to begin soon, and the country's reliance on HIMARS, solutions are now more important to make sure Ukrainian soldiers can gain significant advantage.

It's still one thing to successfully oppose the Russians at their current location. Another goal for them is to drive out the Americans, the retired US Army Brig. said. Gen. Steven Anderson explained to CNN. They're sunk in, they've been there for a year.

Ukraine needs to keep HIMARS in the game

HIMARS has been of great importance, he said. They must have the capacity to preserve these HIMARS and utilize them to perform effective punches.

Ukraine has currently received 18 American HIMARS, and the U.S. has pledged to send 20 more. Other members of NATO have given 10 Multiple Launch Rocket Systems to the State Department, according to the Department of State.

The common proclamations from the Biden administration regarding hundreds of millions of dollars in military aid for Ukraine, including one on Wednesday, typically include HIMARS weapons, called GMLRs, as the most significant item. However, the exact number is not revealed.

The U.S. has also assisted the Ukrainians in locating the Russian jammers and destroying them, a "important priority" task, according to a concealed document in the Pentagon that was part of a volume allegedly leaked by Airman Jack Teixeira.

The document continues by advocating for the continued destruction of jammers as much as possible.

GPS jamming can adversely affect other "intelligent'' US weapons like the guided Excalibur artillery shells that are fired from Howitzers and the air-dropped bombs called JDAMs. The document with the leaked Pentagon described the JDAMS as being particularly vulnerable to the disruption.

A U.S. official acknowledged that the U.S. has advised the Ukrainians on how to recognize and destroy the Russian jammers, because there is only a limited number of ways to alter HIMARS and their rockets.

The Russian Navy has installed temporary GPS jammers on at least one of its warships ahead of a high-profile naval parade in St. Petersburg, according to experts.

An image published Wednesday by military and open source intelligence analyst H I Sutton shows a photo of a Russian Navy frigate taken in Russia's second largest city on July 14 that appears to show multiple sets of GPS network jammer installed on the ship's exterior.

Newsweek could not independently verify the date and location of the video. However, military expert David Hamblin said the presence of GPS jammers on the ship does indicate that the Kremlin fears that Kiev, Ukraine supporters or anti-Putin groups will plot drone attacks. Samuel Bentt of the Center for Naval Analysis said it was "entirely feasible" that Moscow chose to use cell phone jammer and had done so before the war in Ukraine. But he told Newsweek that the evidence is limited and it's hard to judge.

The drone threat: GPS jamming systems and available countermeasures

While GPS jamming may not be the first thing on the minds of many drone operators, government and civilian customers around the world are vulnerable to GPS jamming technology, which can cause expensive drones to drop from the sky when hackers attack GPS access with easily accessible tools. Because the satellite GPS signals that actually reach vehicles and drones are quite weak, using radio frequency transmitters that operate at the same frequency as GPS can have catastrophic effects, as seen in the attack on a light show in Zhengzhou, China, where hundreds of drones crashed to the ground.

Typically, denial-of-service attacks on GPS networks are launched by powerful radio frequency transmitters that can use a variety of methods to try to interfere with satellite connections between drones or vehicles and satellite networks above them. To solve this problem, anti-jamming devices can try to change the direction of the high-frequency beam (using beamforming or steering), or dampen the attack frequency and create "invalid zones," which are more effective but more difficult to roll out.

Other experts were skeptical about the extent to which the images revealed possible interfering features on board.

It has been speculated that the potential jamming system could be part of the R-330Zh Zhitel(on-board system), or it could be part of the Pole-21E jamming system. Newsweek has contacted the Russian Defense Ministry by email for comment.

Hamblin told Newsweek that Russia has an "extensive" track record of using GPS jamming - blocking GPS reception and "spoofing," showing the wrong location on trackers - to fend off drone attacks.

The first military parade was held in Russia's second largest city in 2017, TASS reported.

Drones and rapidly developing unmanned technology have played a major role in the war in Ukraine. Both sides want to use drone technology to inflict damage on critical infrastructure at low cost, and experts say the ongoing conflict has sparked drone innovation at "lightning speed."

But the Kremlin has said in recent months that beyond Ukraine's borders, Moscow itself has been repeatedly targeted by drone strikes.

On May 3, Russia said two drones had struck the Kremlin in what it called a "planned terrorist attack and assassination attempt against the president" ahead of annual Victory Day military celebrations. The Russian leader said in a statement that the drones were "intercepted on Kremlin territory, with debris scattered and without causing any casualties or damage".

"Russia reserves the right to take countermeasures at the time and place it deems appropriate," the Kremlin added.

Moscow has blamed Kiev for the attack, but Kiev has denied carrying out the drone strike

Later that month, the Russian military said eight Ukrainian drones had struck wealthy neighborhoods in Moscow, damaging several buildings. Three of the drones were neutralized by electronic warfare, the Russian Defense Ministry said at the time, adding that the remaining five were intercepted by the Pantsier-S air defense system.

On July 4, Moscow accused Ukraine of firing five drones at the Russian capital, saying four of them were destroyed by Russian air defense systems and the fifth was "neutralized by electronic warfare."

Russia's defence ministry said flights at Vnukovo airport, one of Moscow's main transport hubs, had been disrupted but there was no damage to infrastructure.

"Given the recent spate of drone strikes in Moscow, the main concern may be an aerial attack," Hamblin said of the Navy Day parade. But Russia has also accused Ukraine of using unmanned surface ships to carry out attacks on annexed territory in Crimea, attacking Russia's Black Sea naval base in Sevastopol and the Kerch Bridge, a key crossing point connecting Crimea to the Russian mainland.

Experts told Newsweek earlier this week that this type of attack, which typically uses improvised water drones, is one that Russia's defenses are inadequate for.

Hamblin said, however, that an attack on Russian forces in St. Petersburg on Navy Day seemed unlikely due to the distance between Ukrainian territory and the Baltic city.

Don let phone notifications stress you out

With all those smartphone notifications, it's no wonder you lose focus on whatever you're trying to do.

Your phone doesn't even need to ping to distract you. It's well-documented that just the presence of your phone, silent or not, is enough to distract you.

what happens? More importantly, how can you refocus your attention without missing out on what's important?

Is it really such a big deal?

While estimates vary, the average person checks their phone about 85 times a day, about once every 15 minutes.

In other words, every 15 minutes or so, your attention may drift away from what you're doing. The problem is, it can take a few minutes to fully regain your focus after being interrupted by your phone.

If you're watching TV, getting distracted (and refocused) is no big deal. But if you're driving, trying to study, work, or spend time with loved ones, it can cause some pretty serious problems.

Cellphone Jammer, a DIY endeavor for the darker crowd. I'm pretty sure we've all considered having one at some point: whether the obnoxiously loud woman next to you is announcing private bedroom stories to a crowd on the subway, or your kids are grounded from using the phone (and consequently snagged a hidden prepaid phone), sometimes having a cell phone signal jammer comes in handy.

What do all these disruptions mean for cognition and well-being?

There is growing evidence that push notifications are associated with reduced productivity, poor concentration, and distraction at work and school.

But is there evidence that our brains are working harder to handle the frequent switches of attention?

A study of people's brainwaves found that those who described themselves as heavy smartphone users were more sensitive to push notifications than those who described themselves as light users.

Heavy users were significantly worse than light users at regaining focus on the task after hearing a push notification. Although push notifications interrupted the concentration of both groups, heavy users took longer to refocus.

Frequent interruptions from your phone can also make you feel stressed out by the need to respond. Frequent smartphone interruptions have also been linked to increased FOMO (fear of missing out).

If you get distracted by your phone after responding to a notification, any subsequent delays in getting back to the task can also make you feel guilty or frustrated.

There is certainly evidence that the longer you use your phone in an unproductive way, the lower your rating of your own happiness is.

Mr. Larson of the cellular industry group said that while the industry objected to imposed controls on cellphone ringing, it did not oppose measures left to the customers' discretion. ''They are certainly less odious than gps blocker,'' he said.

How can I stop?

We know that turning your phone to silent won't magically solve the problem, especially if you're already checking it frequently.

What is needed is behavior change, but it is difficult. It may take several attempts to see lasting changes. If you've ever tried to quit smoking, lose weight, or start an exercise program, you know what I mean.

An company Perfectjammer, makes a detector called Wireless Signal Detector Prevents Monitoring, a hand-held device that is used to monitor and detect cellular communication activity in a given area. (It is offered at www.perfectjammer.com for $100-$380.) Other smaller detector models include the RF Signal Detector from TG-007B, about the size of a beeper, which costs less than $100. As with wifi jammers, the larger the detector, the greater its range.

Start by turning off all unnecessary notifications. If you want to check your phone less often, here are some things you can try:

In that moment, interrupt the urge to check and actively decide whether it will work in your favor. For example, when you turn to reach for your phone, stop and ask yourself if this action serves a purpose other than to distract.

 

While federal law prohibits the use of radar signal jammers throughout the United States, laser jammers are legal in most states, but the following states have explicitly banned their use: California, Colorado, Illinois, Minnesota, Nebraska, Oklahoma, South Carolina, Tennessee, Texas, Utah, Virginia, Washington, D.C.

Penalties vary by state. In Texas, for example, the maximum fine is $500, while in Utah violators can face up to 90 days in prison and a $750 fine.

Military Eliminates Iraqi GPS Jammers

WASHINGTON - The president spoke with Russian President Vladimir Putin on Monday about the sale of sensitive military equipment to Iraq, but the discussion may have been moot as military officials said they had destroyed six GPS jammers.

Air Force Maj. Gen. Victor E. Renuart Jr. told a news conference Tuesday at U.S. Central Command at Camp Sariyah, Qatar, that six GPS jammers "supplied by other countries" have been deactivated by U.S. forces.

We took out a GPS jammer with a GPS weapon

Renuarte did not specify that the cellphone jammers were part of a shipment of supplies from Russian companies to Iraq, but the U.S. has repeatedly expressed concern that Russia is allowing the supplies to slip through Iraq in violation of decade-long U.N. sanctions.

In a call to Putin on Monday morning, White House spokesman Ali Ali expressed concern over reports that Russians were actually on the ground in Iraq teaching Iraqi troops how to use prohibited hardware such as night-vision goggles, GPS jammers and anti-tank missiles. Fleischer said.

GPS jammers in particular slowed the bombing of Baghdad as the military took extra care not to hit civilian targets

Iraq may have acquired as many as 400 electronic "jammers" that could divert U.S. smart bombs from their intended course if the U.S. went to war.

The Pentagon has "genuine concern at the highest levels" that Baghdad may have purchased the wifi jammers from a Russian company.

The types of bombs that can be redirected by these jammers are called "J-Dams" -- "Joint Direct Attack Munitions" guided by global satellites. These are military GPS-guided bombs.They cost around $21,000 each and have a maximum range of 15 miles. The J-Dams debuted in Kosovo in 1999.

The Air Force is now trying to test similar jammers to see if those used by enemies work against American weapons

Federal officials say Iranian forces are actively using GPS jammers and impersonating U.S. or allied warships to lure merchant ships through Iranian waters and then seize them.

The U.S. Department of Transportation's Maritime Administration issued a warning that Iran was using "GPS jamming, bridge-to-bridge communications spoofing, and/or other communications jamming with little warning."

"In at least two of these incidents, the ships reported GPS jamming," the statement read. "The ships also reported spoofed bridge-to-bridge communications from unknown entities falsely claiming to be U.S. or coalition warships."

 

A small surveillance drone flew over the Austin stadium, diligently following a series of GPS waypoints programmed into its flight computer. On the face of it, the mission was routine.

Suddenly, the drone veered sharply off course, deviating from its intended flight path and hurtling east. After a few minutes, when it was clear that something was seriously wrong, the drone made a sharp right turn and headed south. Then, as if some ghost had ordered the drone to self-destruct, it hurtled toward the ground. Just a few feet from some kind of disaster, a safety pilot with a radio control device saved the drone from crashing into the scene.

On the sidelines, there were smiles all around about the near-disaster. Professor Todd Humphreys and his team at the University of Texas at Austin's Radionavigation Laboratory have just completed a successful experiment: closing a hole in the government's plan to open U.S. airspace to thousands of drones.

They can be turned into weapons

Spoofing the GPS receiver on a drone is just another way to hijack a plane

In other words, with the right equipment, anyone can take control of a GPS-guided drone and make it do whatever they want.

Spoofing is a relatively new problem in GPS navigation. So far, the main problem has been GPS jammer device, which are easily available via the Internet and used by people to hide illegal use of GPS-tracked company vans, for example. Iran is also believed to have shot down a US spy drone in December by jamming drone its GPS, forcing it into automatic landing mode after losing direction.

"Tricking the GPS receiver on a drone is just another way to hijack a plane." Todd Humphreys, a researcher at the University of Texas Radio Navigation Laboratory

Cell phone jammer can cause problems by disrupting GPS signals, while spoofers are a huge leap forward in technology. They can actually manipulate navigation computers with false information that looks real. He used his device - what Humphreys says is the most advanced spoofer ever built (which costs just $1,000) - to infiltrate the drone's GPS system and send out a signal more powerful than those coming from satellites high in Earth's orbit. .

Initially, his signal matched that of the GPS, so the drone thought there was nothing wrong. That's when he strikes - sending his commands to an onboard computer to get the drone to follow his lead.

Mr Humphreys said the impact was severe. "Within one to three years, the airspace will have 20,000 drones," he told Fox News. "Every one of them could be a potential missile aimed at us."

Drones have been widely used in places like Iraq, Afghanistan and Yemen, but so far GPS-guided drones have been limited to battlefield or southern border patrols and have not been allowed to fly widely in U.S. airspace.

Under pressure from the Pentagon and drone manufacturers, Congress ordered the FAA to write rules allowing government and commercial use of drones on U.S. soil by 2015. The plan could eventually see police drones spying on U.S. cities, drones monitoring power company transmission lines, or GPS-guided freighter-sized drones delivering packages across the country without a driver. FedEx founder Fred Smith said he hopes to add drones to his fleet soon.

The new rules have raised privacy concerns about a "surveillance society" where drones tirelessly monitor our every move 24/7. But Humphreys' experiment puts a whole new spin on anxieties about drones.

"What if you could shoot down one of these drones delivering a FedEx package and use it as your missile?" It's the same mentality as the 9-11 attackers."

This is something the government is acutely aware of. In the deserted desert of the White Sands Missile Range in New Mexico, officials from the FAA and Department of Homeland Security watched Humphrey's team constantly take control of a drone from a remote mountaintop. The results were as dramatic as the test at UT Stadium a few days earlier.

The Department of Homeland Security is trying to identify and mitigate gps jamming with its new Patriot Watch and Patriot Shield programs, but the effort is poorly funded, still in its infancy, and mostly aimed at finding people using jammers rather than spoofers.

The potential consequences of GPS spoofing are simply chilling. Humphries warned that terrorist groups could match his technology and wreak havoc in crowded U.S. airspace.

"I'm afraid they're going to crash into other planes." "I'm worried they're going to crash into buildings. We could have a collision in the air and there could be casualties, so we want to prevent that from happening and fix it."

Unlike military drones, which use encrypted GPS systems, most drones flying over the United States will rely on civilian GPS, which is not encrypted and can be easily infiltrated. Humphreys warned that the government needed to address the loophole before allowing drones widespread access to U.S. airspace.

"It just shows the mindset that we had after 9-11, when we reinforced the cockpit doors to prevent people from hijacking airplanes - well, in terms of the navigation systems of these drones, we need to adopt that mindset."

The EMP generator generates an electromagnetic pulse to disrupt electronics

U.S. Customs and Border Protection (CBP) officers in Wisconsin recently seized a slot jammer device while inspecting a shipment from Hong Kong.

CBP officers made the discovery at the Milwaukee port of entry on Feb. 4, CBP said in a press release.

Electromagnetic pulse (EMP) devices are banned by the Federal Communications Commission and are used to "interfere" with the inner workings of slot machines.

According to U.S. Customs and Border Protection, an EMP generator generates an electromagnetic pulse that can disrupt electronic devices at a range of about one meter. These devices typically send an electric current through a magnetic field via a magnetic copper wire.

Border Patrol agents in Arizona have shot dead Mexican migrants at the US border

CBP said the shipment was a car adapter from an electronics supplier in Hong Kong and was headed to a home in Mossini, about 175 miles northwest of Milwaukee.

"There are a variety of ways these tools can be used," LaFonda D. Sutton-Burke, Chicago's director of field operations, said in a statement. "Federal law prohibits such cellphone jammer because they can be used to interfere with radio communications, cellular phones, GPS and other communications devices."

CBP officers at the Port of Milwaukee Express Consignment Operations facility examined the shipment and sent it to the Mechanical Engineering Division at FBI Headquarters for further analysis.

We have become very dependent on global positioning. A power outage will cost us billions of dollars. And there is no backup yet.

The dire threat of GPS could cripple corporate America

A growing problem for GPS: There is no backup system in the United States. Most of our critical infrastructure, including power grids, banks, transportation systems, and telecommunications networks, relies on GPS. In addition to traffic maps and other positioning services, GPS is used for high-precision timing required for high-speed financial transactions, wireless network synchronization, and grid synchronization. But the rising risk of severe blackouts has gone largely unnoticed. "I don't think GPS vulnerabilities have gotten a lot of attention because, unlike cybersecurity, there haven't been any major disasters," said Marc Weiss, a fellow at the National Institute of Standards and Technology.

GPS and other timing systems will become even more important to modern life in the future. With the rise of connected sensors, devices and machines (i.e. the Internet of Things), timing signals need to be more precise. A government report last year concluded that a lack of high-precision timekeeping systems could hinder the development of new technologies, such as instantaneous collision avoidance systems in cars or communication links in smart grids.

The United States is at greater risk than countries such as Russia, China, Iran, Saudi Arabia and the United Kingdom, all of which have some form of ground backup. GPS outages happen from time to time because the signal is weak and highly susceptible to interference. "Terrorists can just use a GPS jammers to carry out an attack," Goldward said. Each jammer costs less than $50 and is extremely difficult to track and stop. Note that companies such as Spirent UK provide equipment to assist in the detection of GPS interference to help combat such interference.

The Global Positioning System provides navigation for our ships at sea. It is at the heart of the new next-generation air traffic control system. It can even time-stamp the millions of financial transactions that take place around the world every day.

GPS faces threats from terrorists, rogue states and $50 cell phone jammer

• Criminals, terrorist groups and rogue states, even those with a basic GPS jammer you can buy for $50 on the Internet, face extreme challenges, said Todd Humphreys, a GPS expert at the University of Texas. big risk.


• "If you were a rogue state, or a terrorist network, and you wanted to cause some massive damage - maybe not an explosion, but an economic attack on the United States - that's what you might do." As a weakness," he told Fox News.


• Humphreys was the keynote speaker at the UK ICT Knowledge Transfer Network's World Experts Conference in London. His predictions about the prospects for this emerging threat are dire.

In 2010, for example, British researchers aimed a low-altitude GPS signal jammers at a test ship in the English Channel. The results were shocking: the ship went off course without the knowledge of the crew. Passing false information about their location to other ships increases the likelihood of a collision. The communications system stopped working, meaning the crew could not contact the Coast Guard. The emergency services system used to guide rescuers is completely out of order.

1. Then there's the disappearance of a U.S. drone over Iran. Humphreys believes Iranian authorities confuse the ultra-sophisticated RQ-170 spy drone into landing mode by using simple jamming techniques. The drone's Achilles' heel? It has a civilian GPS system, not a military-grade encrypted model. It doesn't take much to blind it and force it down.




2. Another threat that is burgeoning is so-called "spoofing." Unlike gsm jammer, which block or scramble GPS signals, "spoofers" mimic information from satellites. It can fool an aircraft, ship, or other GPS-guided device into thinking it's somewhere, but it's not.




3. Organized crime is already trying to exploit this possibility, Humphreys said. A criminal gang may hijack a container truck full of high-value cargo and trick the owner into thinking the truck is heading to a predetermined delivery point instead of the gang's warehouse.




4. Hanvers: "Civilian GPS signals are completely open and vulnerable to spoofing attacks because they have no authentication and no encryption. It is almost trivial to imitate these signals and trick a GPS receiver to track your signal." Authentic ."



5. Hijacking a container is one thing. Deceiving the global financial system is another matter. Another emerging GPS threat, Humphreys warned in a speech in London, is global stock and commodity trading networks.

Every transaction is time-stamped using a GPS clock. Computer programs monitor these timestamps with millisecond precision. If something goes wrong, many projects will be taken off the market. Hackers could easily interfere with these timestamps, triggering trading procedures, causing sudden liquidity crises and potentially mini-market crashes, Humphreys said.

Manipulating time, then, pays high dividends. An unscrupulous trader or criminal organization can make millions of dollars by delaying time even by a fraction of a second.

"You're able to match prices between networks in a different way than anyone else in the world," Humphreys said. "Everyone else in the world might be off by 20 milliseconds, and you happen to know the actual time. So you can buy low in one market and sell high in another."

These devices are illegal in the US, but can be easily obtained on the Internet for as little as $50. People use them to avoid tolls, to hide from the prying eyes of their spouses, or to use company vehicles for unintended purposes. This sometimes has unintended consequences.

Devices that interfere with GPS may actually have a legitimate purpose: to protect individual privacy, he said.

"People have a right to privacy in their own lives," he said. "However, having a small dot-sized GPS tracking device to be able to secretly locate them at your friends - they would want to resort to some kind of jamming or deception to defend against this invasion of privacy."

 

Safety zealot hid a phone jammer in his SUV to stop other drivers taking calls

If you happen to notice a second-hand Toyota Highlander being offered for a quick sale in Seffner, Florida, you'll know exactly who it belongs to. A local man, Jason Humphreys, has been given 30 days to pay a $48,000 fine after being caught radio-handed with a high-powered phone jammer hidden under his SUV's front passenger seat. When he was pulled over by a squad of FCC agents and police officers, who had spent days tracking the source of the wideband interference emanating from his vehicle, he reportedly told them that he was "fed up with watching cell phone usage while people were driving." Unfortunately for Humphreys, the state of Florida deems it legal for motorists to engage in phone conversations while they're on the move, whereas it severely frowns on the use of unlicensed jamming equipment that can disrupt vital communications between emergency services. The only glimmer of hope for this grumpy vigilante is if he can write to the FCC and somehow stall the fine, but even then he'll likely still face a separate case raised by an even grumpier Sheriff's office.

Drones can defend themselves with an anti-laser jammer

Helios prevents laser weapons from locking on.

There are plenty of efforts to make drone-destroying lasers. But what about protecting those drones? Adsys Controls thinks it can help. It's making Helios, a passive jammer that confuses laser weapons. If it detects an incoming laser beam, it detects the traits of that beam (such as its pulse and wavelength) and interferes with them to prevent the laser from locking on and toasting the drone. The company won't say exactly how this interference works, although it may be a counter laser. The one certainty is that it's reliable -- this is "permanent protection" against subsequent lock-on attempts, not just a momentary break.

You may have to wait a while to see Helios in action, since there's no mention of contracts at the moment. Also, it's not certain how well this works. Can a laser target a part of the drone without the jammer catching it? And is the system quick enough to stop higher-power lasers that can burn a drone within a few seconds at most? Still, drones don't really have anti-laser defenses right now. Any protection is bound to be helpful, and Adsys' solution could be highly effective if it lives up to the hype.

 

 

Break-in suspects using cell-jamming technology to avoid surveillance camerasCell-jamming uses devices to interfere with radio or wireless signals.According to CMPD, thefts have figured out how to evade surveillance cameras in some home break-ins, utilizing technology in the process.

It's called cell-jamming, and happens when a person uses a device to interfere with radio or wireless signals.

According to the Federal Communications Commission, "the use of a phone-jammer, GPS blocker, or other signal jamming device designed to intentionally block, jam, or interfere with authorized radio communications is a violation of federal law. There are no exemptions for use within a business, classroom, residence, or vehicle."

Cell-jamming could happen from a device roughly 30 feet from the intended target, or home cameras.

 

Rogue toy drones - a hot Christmas gift this season and last year - are beginning to disrupt military operations at multiple bases across the country. Sales of consumer drones are expected to approach 700,000 this year, and military officials say they are bracing for the problem to get worse and fear a possible aviation disaster.

How to stop terrorist attacks using commercial drones

In June 2015, an Air Force KC-10 aerial tanker flying at an altitude of 3,800 feet over suburban Philadelphia was forced to take evasive action and narrowly avoided hitting a football-sized drone that passed within 10 feet of its right wing.

According to reports filed with the Armed Forces or the Federal Aviation Administration, there were at least 35 cases of small drones interfering with military aircraft or operating too close to military airports in 2015.

Previously, close encounters with rogue drones were almost unheard of. But rapid advances in technology and falling prices have led to a boom in sales - and a corresponding surge in reports of air traffic chaos.

According to Federal Aviation Administration (FAA) guidelines, drone pilots flying for recreational purposes should keep their aircraft below 400 feet and at least five miles from airports. However, regulators have been largely unable to enforce these guidelines.

How does GPS/GNSS apply to drones?

Unmanned aerial vehicles (UAVs) are increasingly being used for a wide range of applications, including reconnaissance, surveillance, mapping, space information acquisition, and geophysical exploration. Often, in these situations, GPS is the key to safely operating the drone.

Drones are commonly used for Earth observation measurements, utilizing cameras and radars installed for this purpose. In order to accurately refer to the collected data, it is important to know the exact position of the vehicle when taking measurements or taking photos. A drone gps blocker receiver can pinpoint the precise location of a drone, often to the centimeter. The same concept applies to the exact time when a photograph is taken or a measurement is taken. The precise time stamp provided by the drone's GPS is invaluable for gathering such information.

 

 

 

 

They are cheap, lightweight and can carry small bombs; For groups like Hezbollah, Daesh (also known as the Islamic State, Islamic State, and ISIS), or any other group that wants to wreak havoc on budgets, commercial drones are essentially a new tool of terror.

"This is the quadcopter you can buy on Groupon or go to Sam's Club for $400," Gen. Robert Neller, Commandant of the U.S. Marine Corps, told a forum in Washington on the future of warfare.

Even before the Federal Aviation Administration unveiled proposed regulations for commercial drone flights in the United States last week, one company was already using drone jammer to collect data from unsuspecting citizens in Los Angeles.

AdNear, a Singapore-based location-based marketing company, uses a fleet of off-the-shelf consumer-grade drones to determine the location of a cell phone jammer and its movement by collecting signal strength and other wireless data from passers-by below. With this data, AdNear can offer highly targeted advertising and other promotions to potential customers as they pass through the storefront to incentivize customers to come into the store.

While collecting data from wireless transmissions via drones may be a new concept for marketers, Black Hat hackers have taken an interest in it, having demonstrated the ability to snoop on phones and Wi-Fi networks by using drones to impersonate cell towers, other transmission endpoints.

A string of recent drone-related incidents, including the crash of a drone on the White House lawn in 2015, may not have helped.

The drones, which have varying degrees of advanced weaponry, are currently being used in Syria's civil war and in parts of Lebanon and Syria bordering Israel, where Hezbollah holds a dominant position.

One solution is to use electronic signal jammers to prevent drone operators from flying within a specific area, an approach that has been studied by the U.S. military.

These drones are highly advanced platforms with technology and a price tag that puts them out of reach for all but the most advanced militaries.

Many cheaper, lighter models were more readily available to the guerrilla masses.

Their simplest use is to spy on American activities.

But what worries U.S. military tacticians is their potential for modified, more lethal uses.

 

As British car thieves use GPS jammers to escape, it's only a matter of time before American scammers - and, ominously, terrorists - catch on.

Jammers emit low-power signals, creating signal noise and tricking GPS receivers into thinking the satellite is unavailable. They can be used to confuse police and avoid tolls, and some pranksters have also used them to annoy unsuspecting iPhone users.

But the real threat is unknown. Criminals can use them to hide their tracks from law enforcement, and some experts worry that terrorists could use high-powered jammers to disrupt GPS reception on planes or during military operations.

These devices pose a serious social risk, and their purchase and use in the United States is unquestionably illegal. The FCC is optimistic about going after anyone who buys a GPS jammer and will prosecute and jail anyone who uses one. Yet they are easy to buy online, and their supporters say they should stay that way. Fox News can purchase GPS jammers from numerous online sources for as little as $50.

"GPS is closely linked to the transport, manufacturing and economy of our society, so the stakes are high," said David Last, emeritus professor at Bangor University in the UK and a leading authority on the criminal use of GPS jammers.

"This is especially true in telecommunications: GPS is the ultimate source of timing for most of our phone systems, for the Internet, and for cellphones in the United States."

 

All of these systems are potential prey for signal jammers, which is the main reason they are illegal. But supporters of the devices say they can serve a purpose and that people should have the right to buy them. And, for now, they can.

perfectjammer.com, a Shenzhen-based company, sells cigarette lighter jammer for $99.99 for its satellite signal. perfectjammer.com offers shoppers free nationwide shipping through UPS, FedEx and other companies.

that GPS jammers can be stowed easily in a car or a bag and can help avoid spy detection -- say,  from a spouse who suspects infidelity and plants a GPS tracking device like the Zoombak in a car.

"Our new cigarette lighter jammer is designed to block all possible tracking systems as well as all civilian GPS systems, including GPS L1, GPS L2, and GPS L5. To run the GPS jammer, you simply turn on the switch at the top of the jammer."

But Bruce Romano, legal counsel for the FCC's Office of Engineering and Technology, said that's not a good enough reason to use jammers. Anyone can hire detectives to scan cars or personal belongings for GPS receivers, he said.

"In addition to breaking the law, or [criminals] thinking they can use them because customs won't detect them, there are all sorts of critical devices that could be affected and could have unintended consequences that could cause problems, and you have no idea that you caused them," Romano said.

 

 

The Air Force, which deploys and maintains GPS satellites, acknowledges that GPS systems are vulnerable because they are widely used by the public.

Of course, GPS and cell phone jammer are not the most advanced. These devices, which cause signal confusion and disruption, are actually similar to illegal cell phone jammers.

This risk is low for aircraft, which use ground-based radar for guidance and have backup navigation systems that do not rely on satellites. Military personnel use a dedicated GPS network. But GPS interference can still cause cockpit chaos, as pilots have to switch to a backup navigation system. Shipping that relies on GPS coordinates to locate ports could also face problems.

Ronald Repasi, deputy director of the FCC's Office of Engineering and Technology, said it is illegal to sell, import, possess or use GPS jammers in the United States, and he said the agency aggressively pursues those who use them. He said GPS jammers could pose a potential risk if used incorrectly.

"It depends on the capability of the jamming device," Repasi said. "High-power devices have a larger range and are more likely to cause interference over a wider area than low-power devices."

 

 

 

Service station thieves use car key jammer

Police have warned that thieves are using radio signal jammers to steal from cars parked at motorway service stations.

Thames Valley Police said the transmitters could be used to "interrupt" the signal for the remote key, thereby preventing the vehicle from being locked properly.

Police said 14 truck, van and car thefts had been reported recently, but there were "no obvious signs of burglary."

It advised motorists to check their vehicles before leaving them unattended.

Burglaries were reported in the Chieveley, Reading and Membury service areas on the M4 in Berkshire in the last two weeks of November.

 

How does a radio jammer work?

The remote key has a unique signal that is transmitted from the remote key to the car via radio waves. Portable jammer suppress the signal from the owner's key and interfere with this communication.

These devices can be used on a large scale, theoretically allowing thieves to cover an entire parking lot.

Potential thieves rely on drivers to press the lock button on the keychain but forget to double-check that the vehicle is secure, thereby leaving it open for easy access.

More modern vehicles that use keyless entry may also be vulnerable.

 

 

Car key Jammer: What you need to know

With tech-savvy thieves reportedly using electronic devices (" key jammers ") to prevent car locks, what do you need to know about this growing crime?

The transmitters, which are easy to buy online, can be used to interrupt the keychain's signal, meaning careless motorists will think their car is safe when in fact it is not.

This gives thieves an easy way to steal your belongings or even the car itself.

A relatively low-power gps blocker has a range of about 75m, which means that a considerable area (such as an entire parking lot) could be affected at the same time.

But wifi blocker wielding scammers can strike anywhere, not just public parking lots.

Deputy Chief Constable Matt Jukes, of the National Police Chiefs' Council, said although he believed the problem was minor at the moment, it was "a growing feature of vehicle crime".

"The Vehicle Crime Intelligence Unit is working closely and extensively with a number of partners, including the Home Office and car manufacturers, to develop solutions to prevent this crime now and in the future."

Loran Dover contacted the BBC to say the incident had happened to her on a residential street in Leeds.

"When I got up to get ready for work, I went outside and found all the car doors closed.

"When I knew I'd locked the car, I was mortified to think I'd just left it behind - I was staying at my boyfriend's house and had to leave Christmas presents in the car. But when we actually looked inside, the whole car was ransacked and everything of value had been taken.

"The police initially said they would not take any action. No one was even sent to check for fingerprints, because there were no obvious signs of a break-in. But when I called the bank to cancel my card, the thieves kept using it." Non-contact type. That's when the police really got involved and took the matter more seriously.

"They are currently watching CCTV and hopefully they will catch them."

 

 

Are cell phone jammers legal in schools?

Are cell phone jammer legal in schools? Whether public and private schools are allowed to use them. Also, if you're worried about using jammers at school, don't worry. You can't use a jammer in school unless it's part of the school's wireless network.

Cell phone jammers are legal in public schools

• Although there have been isolated cases of cell phone seizures in public schools, a high school science teacher has been suspended without pay for using a cell phone jammer in class. Cell phone jammers work by blocking a specific radio frequency to block all cell phone communication. It creates radio silence bubbles and is illegal. It's not clear if cell phone blockers are legal in public schools, but it's certainly illegal to sell or use them in public schools.


• Teachers are increasingly using cell phone blockers in class because they're tired of students texting and talking in class. Teachers want to know how to prevent students from texting and not listening in class. In addition to distracting teachers, cell phones can also reduce students' ability to recall material. Cell phone jammers work by silencing signals from mobile devices. Easy to install at the touch of a button.


• While most students use mobile phones in class, some teachers are reluctant to let students use their phones for social purposes. If students are texting or sending threatening messages, teachers do not allow them to text in class. If a student violates this rule, the higher authorities will intervene. These authorities may include the police. Depending on the severity of the violation, students may face legal consequences or be expelled.

They're illegal in private schools

In British Columbia, a high school principal bought a cell phone blocker from an online dealer. The aim is to prohibit students from using mobile phones during school hours. Although such devices violate federal law, there have been isolated incidents of such devices being used to damage learning environments. The principal may be tired of students abusing mobile phones on campus. In addition to being fed up with students abusing their phones, he may have been motivated by incidents of damage to the learning environment.

The technology on the back of the signal jammers blocks all signals within a certain range by sending out a high-frequency signal. Signals blocked by these devices include Bluetooth devices and wireless networks. In addition, if a student is using a laptop in class, it needs to be connected to the school's wireless network. Using cell phone jammers can interfere with these devices and make them unable to answer emergency calls.

Cell phone blockers are an effective way to eliminate classroom distractions. Portable jammers can be hidden in a teacher's desk drawer or cabinet and can block all calls and texts during class. Using mobile phones in the classroom is a serious distraction, and teachers should take responsibility for preventing students from being distracted. Instead of allowing distractions to interfere with learning, teachers should use technology to keep phones out of the classroom.

Disabling a cell phone jammer is a crime

Canadian law prohibits the use of cell phone jamming devices. While cell phone jammers are illegal, they are not always illegal. Some devices are battery operated. Some look like cell phones with dead batteries. Others are more powerful, requiring power from a standard outlet or even connecting to the vehicle's electrical system. Many of these devices were used in terrorist attacks around the world, including the bombings in Indonesia in August 2002 and in Bali in October 2002. In December 2003, the terrorist attack on Pakistani President Pervez Musharraf was carried out via cell phone.

Using cell phone jammers is illegal in the United States, but not in Canada. Cell phone jammers are being sold on a handful of websites. James Mislan, a former communications electronic warfare officer, said they are an issue that affects personal safety and public safety. While they are illegal in most developed countries, they are not illegal in Canada. Therefore, you should not use them to keep yourself and others safe.

In the UK, police are considering using mobile phone jammers to protect their fleets. In other countries, hotels and other businesses allegedly use them to block cell phone use during hotel stays.

Legitimacy

1. While it's not illegal to use cell phone jammers in the workplace, it's best to check with your employer about the consequences. If you are caught using the FCC in the workplace, there are several ways to get in trouble with the FCC. Some companies use illegal devices such as signal blockers and text blockers, and the FCC has fined them for violating the law. The companies cannot sell the devices in the United States, but they can be purchased online.


2. Cell phones are increasingly used in public places, and this is where cell phone blockers can be very useful. They block signals from nearby mobile devices, rendering them useless. Although the technology is not new, overseas exporters of jammers say demand is on the rise and they are bringing hundreds of cheap gps jammer into the United States each month. Some of the companies buying jammers are hair salon owners, cafe owners and hoteliers. Even bus drivers are buying them.


3. As the threat landscape evolves, effective security measures must be put in place to stay one step ahead. Peace of mind and enhanced security for individuals, businesses and communities.

Can you purchase a signal blocker for personal use?

• If you want to block your cell phone signal, you've probably heard of cell phone signal blockers, but you might be wondering: Can you buy a signal jammer for personal use? Well, there are many reasons why you might want to buy a signal jammers, and here are some of them. It is perfectly legal to use signal jamming devices for personal use, and there are many legitimate applications. Also, you can use it in prison. This way, the jammer will only interfere with signals inside the prison and will not affect commercial signals.




• You can only purchase a signal blocker for personal use if your intended use is legal. The technique is banned in France. In fact, a French father was convicted of personally using a signal jammer to keep his children away from social networking sites. After his children were confined to their rooms due to the Covid-19 epidemic, they became addicted to social networking sites. If you want peace on the train, you may want to discuss the risks.




• The legality of cell phone blockers is a hotly debated topic. There are a lot of legal gray areas when it comes to this technology, but one thing is certain: you may want to use a technology for many different reasons. If you want to protect yourself from prank callers, signal blockers can block unwanted calls and unwanted text messages. In addition, they can be used as listening devices for personal use.




• The first reason to buy a signal blocker is that you don't understand its legal implications. You may have experienced interference from other devices that made you feel scared. Therefore, you must use the signal blocker responsibly and ensure that it does not cause any harm to you or others. This is why you should always check the security seal of a device before buying it. There are several legal issues involved, but you must use signal blockers in a responsible manner.

How do I know if the signal is being interfered with

The process of interference is simple. The source object does not have to send redundant signal PDUs over the network. This uses up valuable bandwidth. Jamming effects are generated by receiving radio objects. And because the radio object is the only one responsible for jamming effects, the source object does not have to send redundant signals over the network. What a waste. This also prevents the signal from reaching its destination.

Another method of detecting interference signals involves using a primary receiver and multiple sub-receivers to generate a composite signal. This process samples the input signal and compares it with the wideband threshold THWB, the narrowband threshold THNB, or the signal received at the narrowband threshold THNB. Once these signals are related to each other, a composite signal is created. This process is effective for minimizing the signal at the primary receiver.

A method for jamming a radio signal includes steps to optimize interference for P predefined regions and locations in a communication network. These methods also take into account the parameters of friendly transmission and receiving platforms to minimize internecine effects on receivers. The anti-jamming system combines signals from multiple sources and produces a narrow beam in the direction of the cell phone jammer.

If an enemy uses jamming techniques, the best defense is to use a different type of antenna. Antennas can interfere with each other, and an enemy station may interfere with signals sent by another station. In this case, it is necessary to change the polarization of all stations and use different antennas. It is also a good idea to use alternative communication routes such as radio relays, as they can be used as relays between radio stations.

Signaljammer - How can you keep your family and friends safe

A signal jammer is a device designed to interrupt communication between devices. They work by mimicking the same frequency range as the target device, disrupting their signal.

The technology has many uses, including in electronic warfare. The Russian military has reportedly been using signal jammers to jam drones flying over Syria. Some of the drones were forced to crash or veer off course. Russia has also been accused of using powerful signal jammers along its eastern border, disrupting phone systems and jamming GPS signals for aircraft flying in the region. In addition to military use, signal jammers are popular with Mexican drug cartels.

Signal jammers are banned in many areas due to the dangers associated with cell phones. They are useful for blocking unwanted calls, ensuring privacy and preventing distractions. Be sure to check your local laws before using any signal jammer device. It may also be illegal to sell or market signal jammers in your country. Before purchasing a signal jammer device, you must seek legal permission. However, the device should be used as directed to avoid any possible invasion of your privacy.

Handheld signal blockers are portable and used to block cell phone signals. However, they require batteries and can only cover a small area. Desktop jammers are larger and can interfere with specific signal frequencies. However, if you plan to limit cell phone service, a handheld jammer may be the right choice for you. It can also be used to restrict Internet access and prevent unwanted phone calls. It is not legal to use a signal blocker in the United States, but it is an effective solution.

What you need to know before buying a signal jammer device

1. If you are going to buy a signal jammer device, you should first know what you need it for. These devices work by blocking all cellular signals. You can install one on your phone or buy a portable one. Depending on the model, you can jam up to six bands at a time. The best signal jammers are usually portable. They can also be used in cars. No matter where they are placed, they will help you avoid being tracked by spies and hackers.




2. However, you should be aware of the potential legal implications of using such devices. They are not easy to use and they are expensive. If you get caught, you will most likely face a hefty fine and possible jail time. However, unlike cell phones, these devices do not affect your Internet connection or landline. If you are concerned about losing service, it is recommended to consult your wireless provider and device manufacturer.




3. Signal jamming is often compared to a denial-of-service attack, in which large volumes of traffic overload a server. By broadcasting noise on specific radio frequencies, signal jammers block the use of those frequencies. Instead of cutting off reception to nearby devices, it disrupts the ability to send and receive calls. It's not a dangerous situation, but it's very inconvenient.

Choose the best signal jammer

When looking for the best signal jammer, you need to consider what features your device needs to have. It is best to choose a device that can control the signal of 2, 3 or 4 GHz devices. The most versatile and effective jammers are portable and flexible, so they can control signals from 2G, 3G, and 4G modes. If you are looking for something suitable for vacation or work, you can purchase a signal jammer that meets your needs and is easy to carry.

Signal strength is an important consideration as it affects interference range, overall performance and durability. High-end GPS jammers have multiple jamming channels, and they are usually more expensive than cheaper single-channel blockers. The cheapest models, on the other hand, can only interfere with specific signals and cannot cover large areas. You'll also want to look for a product with a high-quality cooling fan so it doesn't overheat.

Another place where signal blockers are used is in movie theaters. Often, people use their phones to disturb others, and some people livestream the entire movie on social media. This can have a negative impact on cinema revenue, so having a handheld signal blocker ensures that you won't be disturbed while watching a movie. It's a simple solution to a problem that affects so many people every day. Moreover, signal blockers are an essential part of modern life.

Whether you're looking for a jammer for your phone or other wireless device, the best way to block signals is to buy a product that blocks them all at once. Whether you're looking for a cell phone signal blocker to keep people in their lane while driving, or want to block out noisy offices, there's a jammer for you. So, how to choose the best signal blocker?

There are portable signal blockers and desktop signal blockers. Portable jammers are convenient and easy to hide. They work for a short time and usually cover a small area. Desktop jammers work over a larger area and interfere with specific signals. If you're looking for a long-term solution, the size of a cell phone jammer can be an issue. Choosing the best signal jammer depends on your specific needs and budget.

Before buying a signal blocker, be sure to know which frequencies it can block. Different cellular systems process signals differently, so you need to choose a device that can broadcast at the right frequency. For example, GSM uses the 900 MHz band in Europe, while CDMA and TDMA use the 1800 MHz band in Asia and the United States. But even analog phones can be jammed with signal jammers.

 

If you've ever wondered if owning a signal jammers is illegal, you're not alone. Many people use them to block phone calls and text messages, Wi-Fi networks, GPS systems, and more. These devices not only disrupt the functionality of modern communication systems, but also pose a threat to public safety. The Federal Communications Commission has been noting an increase in jammers imported into the country. However, there are still a few things you need to know before buying a signal blocker.

Cell phone jammers are illegal in the United States, although they can still be found on some websites. According to Mislan, a former communications electronic warfare officer in the U.S. Army, cell phone jammers pose a special threat to law enforcement because they affect the safety of innocent people. As such, he said it is illegal to possess and sell them because the technology causes harm to law enforcement and the public.

Another danger of signal jammers is that they can be dangerous. In the United States and the United Kingdom, car thieves have been known to use them to avoid paying tolls by tricking GPS receivers. However, some pranksters have been found to use these devices to trick iPhone users and get away with crimes. Therefore, it is important to understand the legal implications of having a signal jammer.

Despite the legal risks of owning and operating signal jammers, some countries allow it. India, for example, allows people to use GPS jammers in mosques and schools, as long as they do not extend beyond the walls of buildings. Jammers were also briefly approved for use in concert venues. However, these devices are still illegal in many parts of the world. The law is complex and there is no clear legal advice on the use of jammers.

How does a signal jammer work?

Signal jammers operate by interfering with wireless signals and can disrupt signals from nearby receivers. They interfere with cellular, WiFi, Bluetooth, and GPS signals. The range of signal jammers varies widely, from small handheld jammers that block signals to large military-grade jammers that can block signals for hundreds of miles over open terrain. If you are concerned about the safety of your family, consider purchasing a signal blocker.

While there is no one correct way to use a signal jammer, it is important to understand that different types of signal jammers are used to block different types of communication. Some jammers block only one frequency, while others can jam multiple frequencies at the same time. To block multiple frequencies, use scan jamming or barrage jamming. The latter method is more costly and has a larger interference radius than the former. Unlike scanning jammers, fixed signal jammers require a 230 V power supply and typically operate at a distance of up to 100 meters.

How do I test my phone jammer

Cell phone jammers can be an effective tool in a variety of situations. These devices are designed to cut off the cell phone signal and prevent the phone from contacting the person you are calling. Some examples include a museum that might want to prevent visitors from using mobile phones. Mobile phones reduce museum attendance, so it makes sense for museums to discourage their use. Similarly, movie theaters may want to prevent customers from texting during a movie.

Cell phone jammers come in a variety of sizes and styles. The smaller version blocks cell phone signals between 800 and 1900 MHz. They're blocking the signal within a 30-foot radius. Larger devices, on the other hand, block signals from both networks at the same time. Both types of jammers have their own advantages. Some are smaller and more convenient than personal phones. The smallest model can block cellular signals within a 30-foot radius.

To test the device, you need a digital oscilloscope with a bandwidth of 30MHz. You will also need a power supply to provide a regulated power supply during the test. The device also requires a multimeter to measure resistance, capacitance and current on the circuit board. Since the RF amplifier blocks the direct current, it completely blocks the cell phone signal, allowing only the AC electrical signal to pass through. However, it is important to remember that there are three subcircuits in the cell phone jammer circuit.

The main function of a cell phone signal blocker is to block or limit cellular activity. It can prevent illegal activities and unnecessary phone calls between prisoners. Educational institutions use signal jammers to block cellular signals on campus. In addition to preventing prank calls and other criminal activity, jammers can protect a place's sovereignty and make prison guards or security guards look like modern heroes.

How to use signal jammer

• One way to protect yourself from pranksters and pranksters is to buy signal jammers. The device works by interfering with mobile signals from nearby phones. However, the device is very expensive and bulky and cannot be carried around in a pocket or purse. However, the smallest jammers are lightweight and small enough to fit in a backpack or pocket. You can also find jammers that block multiple frequency bands.




• There are many different types of signal jammers. While some may block phone calls, others may disrupt other signals. Jammers have many different uses, blocking calls to ensure privacy, blocking interference, and even blocking unwanted calls. Before buying a jammer, be sure to check your local laws regarding cell phone use. It is illegal to use signal blockers in public places. However, in some cases you can legally use it.




• To use a signal jammer, you must first determine the desired output power. Omnidirectional and directional jammers are available. Omnidirectional jammers give you 360 degree field of view suppression, while directional jammers only block 180 degree field of view. It is recommended to select jammers according to the range and specifications of jammers. However, keep in mind that each jammer has its own drawbacks.

Many educators do not know how to use electronic devices in the classroom. Some people have been educating students about negative impacts and encouraging them to regulate their use. Others even emphasized the potential applications of mobile devices in the classroom. Although many people just try to ban everything. A principal in British Columbia raised his school's ban to a new level by setting up a cell phone jammer There is only one issue - the device is illegal in Canada. The principal had already ordered Chinese equipment online, but some angry students quickly discovered and told him that he had violated the law. So many ideas. Now, he looks terrible, and using a mobile phone in school now seems to be a civil rights issue for some students.

This seems to have nothing to do with the ban on mobile phones, more to maintain the authority of the school. In this regard... this is completely counterproductive. Many schools have effective mobile phone bans without resorting to technical barriers (I attended such a high school). Perhaps the principal should explain to students and teachers why mobile phones are a problem, develop reasonable usage guidelines, and address the reasonable consequences of violating policies. Compared to installing illegal equipment and being forced to return the same way, this may establish the authority of the principal and win the respect of students.

I just took a deep breath, someone. This may have violated American laws or regulations.

I know that the United States has the strictest laws on interfering with phone operations, so we also have strict regulations on the same topic. But should we?

The problem of interfering with signals stems from the methods used to interfere with the signals. You basically just send a stronger signal at the same frequency as the signal you want to interfere with. This violates the FCC's rules for dividing the spectrum. This is the same reason why pirated radio stations are illegal, despite the fact that many pirated radio stations provide much better signal quality than commercial radio stations.

Why does the owner have no right to prohibit the use of mobile phones on his property.

Electromagnetic spectrum is public property, not private property. The government only reserves some frequencies for public use and permits other frequencies. Breaking this system will ultimately cause electromagnetic damage, making it impossible for wireless signals to work reliably. Do you enjoy having phone features? If that's the case, you like the FCC's regulations on this matter because if their regulations on electromagnetic spectrum are not so strict, your phone may not be able to be used anywhere.

If you don't like it, don't go to concerts, churches, restaurants, funerals, or any other places. Why do we all have to listen to the honking of our phones and the shouting of fools during concerts, funerals, and moving theaters.

The problem is that music halls, churches, restaurants, etc.... Cannot interfere without disturbing nearby people. This is just a matter of interfering with how it works. What these companies can do is build buildings in a way that reduces signal reception. This is completely legal. They just don't allow very powerful signals to be broadcasted on frequencies reserved for public use - that's how 'signal jammers' work.

The Benefits of School Phone Jammer

• Modern education may be one of the most important things that humans ultimately invent, taking into account everything.


• It creates a system in which children can be shaped into highly responsible and capable adults.


• However, many problems often arise within schools. Our modernity and era have brought many astonishing improvements to the way of life of ordinary people.


• Especially with the popularization of smartphones, people have become closer to each other and have gained more information.

The only problem is that some parents who are quite irresponsible in raising their children often purchase smartphones for their children and let them use these devices as they please. Now, generally speaking, there is nothing wrong with children using their phones. Problems only arise when they use them in school. Schools should really start investing in telephone GPS jammers so that children cannot use these devices to distract themselves. When they are in school, their attention should be focused on learning rather than on mobile devices.

If children's phones cannot receive any signal, they have no reason to look at their phones. This can also help them break the bad habit of using smartphones. Smartphone addiction is a very real thing. It is particularly common among children in our world. Give them a few hours during which they will be forced to leave their equipment and rest, which will only benefit them. Even if they don't study during this period, they can at least focus on things outside of social media.

Due to the enforcement of various laws on hidden cameras in various states in the United States, their use may be somewhat ambiguous in law. Generally speaking, it is legal to install home video and recording devices in the property you own (such as those that may be owned by your information hungry spouse during divorce), but if other residents are not aware of these devices, it may violate privacy rights. Of course, before consulting your lawyer about the potential legality of recording devices at home, you must identify these vulnerabilities and hope to prevent them - fortunately, this process is simpler than complex state laws.

Hide camera interception

For objects like nanny cameras that disguise cameras or microphones, simply remove them from your home and store them intact in a safe place (if they are needed as evidence). Paste, plug, or caulk any drilled holes containing hidden eavesdropping devices. If you are lucky enough to find a hidden recording gadget's wired power supply, simply unplugging it is enough to prevent it from recording.

In a more technical aspect, white noise machines or white noise applications can help hide sensitive audio in your home, and even prevent active microphones from picking up available recordings. Similarly, Wi Fi network jammer - typically effective within a range of up to 130 feet - can disable surrounding Wi Fi connections. This means that you may need to work outside the coffee shop for a period of time, but it is a better choice than being eavesdropped.

If you are still not 100% certain that you have found and blocked any potential monitoring devices in your home, then seeking help from a professional is also an option. The professional anti surveillance Service pack detection equipment is far beyond the functions of consumer gadgets, and can suggest you to process or disable anything they detect.

Perform physical scanning

• It may be 2019 now, but finding hidden microphones or cameras still requires some old-fashioned snooping. Check if there are any new or unsuitable objects in your home, even those that have moved slightly - remember that modern eavesdropping devices are usually miniature. Although hidden recorders disguised as other (usually functional) objects have various shapes and styles, some common examples include pens, USB flash drives, USB charging cables and wall chargers, wristbands and watches, Bluetooth speakers, alarm clocks, glasses, bulbs, books, Smoke detector, mobile phone charging stations, and even picture frames.


• When you scan these suspicious objects, please scan the walls of your house for small holes, which are common hiding places for insects. When checking these small details, please pay attention to any wires that you do not know. Although many small listening devices rely on battery power, other devices still rely on AC power. Especially look for USB, mini USB, or USB-C power cables, similar to the charging cable you use to charge your phone jammer. Turning off the lights and performing a visual scan can also help identify any flashing power lights on the camera, while scanning corners and gaps with a flashlight may reveal hidden lens flashes.

Check your Wi Fi

Before you can block recording devices, you must locate them. Like everything from Alexa to Nintendo Switch, most modern eavesdropping gadgets are connected to Wi Fi, allowing them to remotely stream recordings to remote computers. Therefore, the first step in finding hidden recording devices at home is to check if there are any suspicious devices on your Wi Fi network.

To do this, you need to access the settings of the wireless router. Although this process may vary depending on the router, you can usually perform this operation by logging into your account page on the service provider website (or related application), which allows you to manage devices connected to the router or hotspot. If you see any devices you don't know connected to your Wi Fi network, please remove them from the list of registered devices to prevent them from streaming their recordings over the internet.

In some cases, more complex devices rely on their own hotspots or SIM cards to access the internet without having to jump to your home Wi Fi network. Use your computer or smartphone to check for new Wi Fi networks that do not belong to you or your neighbors - you may need to take additional measures (such as wifi jammers device) to block the worm's own network.

Similarly, consumer grade RF detectors can scan the transmitter while you move the detector in space and remind you of the radio frequency through beeps or visual graphics. In the latter case, special attention should be paid to signals within the range of 10 Mhz to 8 Mhz, which is a common frequency of commercial vulnerability use.

The ability to fly cameras over areas to monitor is greatly praised by law enforcement but also hated by activists. Drones can be very fun and useful, but only if they don't fly overhead and invade your privacy. If you're looking for ways to jam and disrupt drone signals, then this article is for you.

How to jam a drone signal? The best way to jam a drone signal is to use a high-quality signal blocker. You can use this device to interrupt or block the frequency that drones use to connect to their GPS system, causing them to lose control and crash.

Fortunately, there are plenty of ways to jam drone signals if the need arises. For each method used to block drone signals, I'll explain how to effectively jam drone frequencies with a step-by-step guide.

 

How to Jam a Drone Signal (Four Ways)

One way to jam a drone's signal is to use an RF jammer. You can buy these jammers online or at retail stores. Radio frequency jammers emit radio waves that interfere with a drone's ability to communicate with its controller so it returns home or lands safely.

 

 

1. Laser
   
   
   
   • While you can use jamming devices to block drone signals, you can also use lasers to block their cameras. This will prevent them from recording the footage, protecting your privacy and personal information.
   
   
   • For this, you'll need a laser pointer, available at most electronics stores and online retailers. Pointing the laser at the drone's camera causes it to malfunction and stop recording.
   
   

 

 

2. GPS Signal Blockers
   
   
   
   • GPS is an essential part of a drone's navigation system. If you want to jam the GPS signal, you need to use a GPS jammer.
   
   
   • A gps blocker is a small device that emits radio waves similar to GPS satellites. They can interfere with the signal, making it impossible for your drone to pick up the signal, making it impossible to determine its location or how high it is in the sky. This could cause your drone to lose control of its flight path and fall out of the sky.
   
   

 

 

3. Frequency jammer
   
   
   
   • This is a device used to intentionally block or interfere with radio frequency transmissions. It is not legal to use them without authorization, but you may be able to obtain a license under certain circumstances.
   
   
   • If you want to jam drone signals and make sure no one can control their drone, then you're going to need an FM transmitter. This is basically an FM radio that transmits on the same frequency as the drone controller.
   
   
   • If your drone gets close enough, it will pick up the transmission and think it's from its controller, which will cause it to fly away from you instead of in whatever direction you originally wanted it to go.
   
   

 

 

4. Anti-Monitoring Jacket
   
   
   
   • One of the easiest ways to confuse a drone is to use an anti-surveillance jacket.
   
   
   • The jacket is made from a material that blocks radio frequencies, which can be used to stop drones from detecting you.
   
   
   • The jacket works by bouncing radio frequency signals from the drone back to the drone itself.
   
   
   • This confuses the drone's sensors so that it cannot see you.
   
   

 

 

What is a drone jammer?

A drone blocker is a device that uses radio waves to disrupt the communication between a drone and its controller. Radio waves can cause the drone to lose control, causing it to crash and/or fall from the sky.

A drone jammer is a device that uses radio waves to jam the signal between a drone and its controller. The jamming caused the drone to lose control, causing it to land.

Drone jammers are used by people who want to keep drones away from them or their property. For example, some homeowners use them to prevent neighbors from flying drones near their homes.

Some people also use drone jammers to protect themselves from being recorded or watched by drones. For example, they are used by police when they want to catch lawbreakers in public places without being recorded by drones.

Disadvantages of drone jamming

Drone jamming is an increasingly popular method of protecting sensitive areas from drone-related risks. However, there are some drawbacks that need to be carefully considered before adopting the technology.

Not Cheap

Drone jammers are expensive and require professional installation and maintenance. But even if you can afford them, they still take a lot of time and effort to keep the area around your property drone-free.

If you want to do it right, you'll need a high-quality drone jammer that can block a wide range of frequencies, and an antenna that can transmit over a wide range.

Interfere with other Devices

One of the main disadvantages of drone jamming is that it can interfere with other equipment, including those used for navigation and communications.

For example, if a drone jammer jams Global Positioning System (GPS) signals from satellites, it will prevent any device from receiving those signals.

How do drone jammers work?

Drone jammers are designed to interfere with a drone's ability to communicate with its remote control. This ranges from using radio waves to block communications (like the latest version of the drone jammer) to jamming the frequencies used by remote controls.

Drone jammers also interfere with the GPS signal that drones use to navigate. The most common type of interfering device is an RF signal generator, which generates static noise loud enough to drown out other signals within range of the device. This static noise is called "white noise" and it can be generated both digitally and analogously.

Drone jammers also come in two flavors: active and passive. Active jammers emit radio energy at frequencies that interfere with the frequencies used by drones or their remote controls, such as 2.4 GHz or 5 GHz.

Passive jammers use electromagnetic interference (EMI) rather than radio waves to block communication between the drone and the controller; this form of drone jamming does not require a power source like active systems.

 

 

Drone signal jammers can be used to block the frequencies drones use to communicate between themselves and their operators. This would cause the drone to lose contact with the operator, making them unable to control it.

Unnecessary surveillance should not be tolerated. If you live in an area with drone activity, consider purchasing a drone jammer and take back your privacy.

Don't let companies violate your rights, invade your personal space. Drone jammers are legal, but if you use them to jam law enforcement or government signals, there can be serious consequences.

Always check your local laws before acquiring a drone jammer, or you could face criminal charges for using it for the wrong purpose.

Be sure to read the instructions on how to use it properly, as well as any warnings about environmental factors that may cause disruption to nearby electronic equipment.

 

Is it illegal to use a signal jammer?

Even though they are legal, is it illegal to use signal jammers? That's the question on everyone's mind. The use of signal jammers in public places is a serious problem that can literally endanger people's lives. While some states do not allow the use of signal jammers in public places, there are some exceptions in the United States. France, for example, has legalized the use of signal jammers in concert halls and movie theaters, and is working on a technology that could let emergency calls through. Likewise, the Indian government has installed jammers in some prisons, and universities in Italy have adopted the technology to prevent cheating.

However, that doesn't mean your workplace cannot be protected from an FCC investigation. The FCC has field agents who can conduct on-the-spot investigations and impose hefty fines. To protect your business from such investigations, you should designate a senior employee to act as a liaison between the FCC agent and your organization. You may also need to hire outside legal counsel to guide you through the audit. Whether or not you use a signal jammer matters, as the fines for infringement are hefty.

However, some people do use cell phone jammers for different purposes. Some people use them to block unwanted calls, while others want to protect their privacy. If you're in doubt about the legality of signal jammers, check your state's laws before buying one. For example, in the United States, signal jammers are illegal if they interfere with cellular communications. In addition to blocking unwanted calls, signal jammers can disrupt important data transmissions elsewhere.

If you want to use a signal jammer in a public place, you need to obtain the appropriate license. Most people who own signal jammers don't need a license. If you're looking for a good signal jammer, make sure it has the proper license. Signal jammers can be used for a variety of purposes, including espionage or law enforcement.

What is a mobile signal jammer?

A mobile signal jammer is an electronic device that interferes with cell phone signals. There are many types, and different frequencies affect different systems. A basic jammer will only block one frequency so that the phone thinks it only has that frequency. More sophisticated jammers are capable of blocking multiple frequencies simultaneously. Some are even able to tune to specific frequencies to block specific signals. These devices work equally well on mobile phones in both analog and digital modes.

The most common jammer is the 450MHz jammer, which requires a noise-shielding signal. Since cell phones use this frequency to tune in, the signal must be weak enough to be unintelligible to the receiver. However, other frequency ranges are likewise contemplated. Therefore, the circuit must have three basic subcircuits: inductor, capacitor, and amplifier. To determine which frequency range will be blocked by the gps jamming device, the first subcircuit is a tuning signal.

How to interfere with cell phone signal?

1. There are various ways to interfere with cell phone signals. Some are easy to use, others are very complex. The first step to using a jammer is knowing which frequency bands your phone is using. Different countries use different frequencies. For example, in Canada, the primary frequency is 1900 MHz and the secondary frequency is 850 MHz. In the US, both the 1900 and 850 MHz bands are used. Europe and Asia use the GSM 900 and 1800 frequency bands. Some countries also have separate frequency bands for CDMA coverage, such as the 450 MHz frequency.




2. When using a jammer, users should know which frequencies to use and how far the signal must travel to be effective. In some cases, false targets can be created by analyzing the strength of the signal received by the radar antenna. For this, you need a jammer with a unique code. It is better to buy jammers with a wider bandwidth than a single frequency jammer. When using a jammer on a single frequency, the RCS of the target and the radar ERP of the jammer need to be known.




3. If you have a business, you may want to block your employees' cell phone signals. This can be beneficial for protecting sensitive information that may leak from your company. In some cases, you may even want to prevent your employees' phones from being used for terrorist attacks. In addition to blocking cell phone signals, jammers can make your phone appear unreachable. They are very effective at blocking calls in confined spaces, and can also be carried in a pocket or handbag.

Choose a Cell Phone Jammer

Cell phone jammers can help you block cell phone signals from other wireless devices. There are three dimensions for choosing a cell phone jammer: power size, signal type, and appearance. These factors relate to how well the device blocks cell phone signals from different locations, such as offices, movie theaters, concert halls, and other public places. While you may be able to find the best cell phone jammer for your needs, keep in mind that making the wrong choice can result in product damage, wasted time, and shipping costs.

Typically, these devices block signals from cell phones within 60 feet of their location. Higher powered versions will create a dead zone the size of a football field. Depending on signal strength, this device may not be effective at blocking all cell phone signals. However, if you are concerned that a cell phone jammer may be operating near you, you should leave the location immediately. Another option is to build a Faraday cage. This will help prevent leaks allowing interfering signals to escape. This will also prevent the signal from passing through the Faraday cage. Although it is illegal to use a mobile phone signal jammer to block the mobile phone signal, it can solve the problem of mobile phone signal very well. And the price is right, as signal shielding equipment is relatively inexpensive.

Drone jammers are an inexpensive and effective way to prevent other drones from flying into your home. Depending on the type of drone you want to block, you can choose a device that interferes with any radio signals the drone uses to communicate.

These uav jammer can be easily built for less than $50 new and less than $50 old.

The Importance of Drone Signal Jammers

A drone signal jammer is a device that prevents a commercial drone from sending a signal to its controller. The device works by simultaneously blocking drone flight control signals and satellite positioning signals. Its powerful jamming capabilities can prevent drones from operating normally. If it detects the presence of a wifi blocker, it will either land, return to the launch site, or plummet to the ground. Therefore, it is necessary to consider the impact of such equipment before purchasing.

Drone signal jammers can prevent crime or terrorism. However, many European countries have banned the sale of these jammers within their borders. Therefore, it is crucial to check local laws before buying. Additionally, you need to understand the risks associated with using drones in your area. These jammers can cause software bugs, which can be difficult to identify. Fortunately, there are legal ways to keep drones from invading your neighborhood.

Protect People and Areas with Drone Jammers

Drones are increasingly dangerous in our world and they need to be protected at all costs. Drones can carry explosives or be used to smuggle illegal goods. To protect people and areas, drone jammers are essential.

A drone jammer looks like a gun and emits electromagnetic noise that overlays the drone's radio signal. Once the drone hits the drone jammer, it will return to its original origin, so operators can track down the pilot and land the drone for forensic investigation. Portable jammer work well against drones, but are illegal in the US. But drone jamming is an increasingly popular solution to security concerns.

How effective are drone jammers for sale?

You've probably seen commercials that sell drone jammers, but how effective are they? Drones use radio waves to communicate. This communication can be via GPS, WiFi or a simple handheld controller. Someone could jam this communication with a drone jammer. These drones aren't the only ones being hit buy jammers. They can also be used by unauthorized devices to spy on people and their property.

When you use a drone jammer, it blocks the signal sent by the drone. A drone jammer will prevent drones from communicating with other drones. This will stop the drone from working and allow you to trace it back to its original location. Additionally, if you capture a drone in an interference zone, you can use the information gathered for forensic investigations. Police will then be able to capture the drone and its owner.

How Drone Jammers Work and Their Range

Drone jammers work by jamming radio and GPS signals up to 400 meters away. For cheaper, simpler drones, the gsm jammer has a much longer range, meaning it won't destroy it. More advanced drones, on the other hand, hover above the ground and crash to the ground if hit by a jammer. In this way, privacy is preserved as the drone does not lose the ability to operate.

The problem with jamming drones is the precision required to be effective. The signal must be focused on the target, which changes direction, angle and speed as it travels. Because the drone is so small, jamming its radio signal requires great precision. Also, jamming the drone's signal will negatively affect other radio signals, which is not what we want to do! However, if we're lucky, we'll have something that stops drones from flying over people.

How to make your own drone jammer

While drones are a growing problem, you can protect your home and family from them by building a drone jammer yourself. DIY drone jammers can be bought online for under $20

If you see any devices you don't recognize connecting to your Wi-Fi network, remove them from the list of registered devices to prevent them from streaming their recordings over the Internet.




• In some cases, more sophisticated devices rely on their own hotspot or SIM card to access the internet without jumping to your home Wi-Fi network. Use your computer or smartphone to check for new Wi-Fi networks that don't belong to you or your neighbors -- you may need to take extra steps (such as a wifi blocker) to block the bugs' own network.

Likewise, consumer-grade RF detectors can scan for transmitters as you move the detector around the space and alert you to radio frequencies with a beep or visual graphic. In the latter case, pay special attention to signals in the 10 Mhz to 8 Mhz range, which is a common frequency used by commercial exploits.

The FCC considers mobile signal jammer illegal because they interfere with the communications of emergency responders who use the same frequencies as them for most of their communications, as well as using cell phones themselves. Yet prisons, schools and city governments have campaigned to allow the use of inhibitors to prevent people from cheating in class, to keep taxi drivers and limo drivers focused on the road, and to limit prisoners' use of prohibited mobile phones.

Since cell disruptors are illegal, they are either illegally ordered from abroad or built illegally at home. You need some real skills to work with microprocessors and antennas. Bubble jammers in particular can jam all types of radio frequencies except cell phones. A lithium-ion battery must be installed for power and can provide two to four hours of suppression, depending on the frequencies around you. The battery can be charged via the USB connector or a regular 4 mm (0.16 in) DC connector. You can also use AAA batteries.

Two antennas in the car gps blocker are controlled by a microprocessor and can pick up various frequencies within a 20 to 25 foot radius. A lot of SMT soldering was required to mount the specific chips to do the job, namely multiple TSSOP and SOT chips, and an RC 0603 with obscure parts and the equipment needed to properly build and debug the device. Since they are illegal in the United States, the origin of these specific contents cannot be obtained.

Inhibidores paracelulars modificados

Some cell phone jammers are repurposed from old cell phones that can use the same frequency and emit a tone that makes conversation over the phone impossible. Again, these are illegal and hard to build yourself unless you have some knowledge and skill in soldering chips and manipulating radio frequencies. Police CB radios work the same way these cell phone jammers try to pick up all frequencies in the vicinity in order to hear them on CB. Cell disruptors go a step further by blocking transmission.

Although the basics behind how a blocker device works may seem pretty simple, it still involves some technical details that may be difficult for a layman to understand. For this reason, we'll start by looking at how phones establish communication with each other.

You must have seen giant cell phone towers in different areas around you. Essentially, every place is divided into zones, and phone signals generated by your device are picked up by cell towers in your area. This means that if you are moving, your phone signal will be picked up dynamically by the corresponding towers as you move through different areas.

So how do jamming devices avoid these complex phone towers? They do this by mimicking legitimate phone signals and transmitting on the same radio frequency as your cell phone. Thus, overwhelming the legitimate signal generated by your cell phone device and hindering wireless communication between your device and cell towers in your area.

Interfering with a cellular signal simply requires broadcasting the correct frequency (or frequencies), and while all devices process signals differently, all cellular devices use radio signals and protocols that can be interrupted, including GSM and CDMA. As a rule of thumb, cellular communications use the 900MHz to 1800MHz band in Asia and Europe, and the 1900MHz band in the US.

Signal jammers can also be classified according to their range, which depends on various factors such as surrounding environment and building density. Low-power jammers typically have a small range and can block wireless activity within 9 meters, while high-power jammers are also effective in areas as large as a football field. Likewise, cell phone jammers used by law enforcement for security purposes can block signals even a mile away.

Plus, signal jammers come in a variety of sizes, from small enough to look more like the phone itself to large enough to be mounted on cars and vehicles.

Travelers should be vigilant as South Korea's hidden camera epidemic spreads

When traveling abroad, it's always a good idea to be alert and aware of your surroundings.

TikTok creator Jazmyn Jennings or @jazmynjenningss recently made a public service announcement for those planning to visit South Korea.

In her video, she exposes the pervasive problem of hidden cameras in public bathrooms in popular tourist destinations.

 

She also advises travelers to consider buying a hidden camera detector and gps blocker so they can protect themselves while heading there.

Wet toilet paper is stuffed in the gaps of public toilets to prevent hidden cameras

Ms. Jennings explained that in South Korea, it is common to encounter public bathrooms with wet toilet paper stuffed in the crevices.

This is to prevent any chance of a tiny spy camera hiding in these tight spaces.

The footage is often streamed online for people to watch, Jennings said.

This problem doesn't just happen in public bathrooms. It also happens in hotels and accommodations, such as Airbnb rooms and other private areas.

Travelers advised to buy hidden camera detectors

If you're planning a trip to South Korea anytime soon, Ms. Jennings recommends buying a hidden camera detector.

These are easily available from online platforms such as Amazon www.perfectjammer.com.

These detectors allow you to check for hidden cameras so you can report or remove hidden cameras if you come across them.

TikToker says today's hidden cameras are "very well camouflaged" and can be hidden in fire alarms, clocks and other everyday blocker devices.

While Ms. Jennings noted that this could happen anywhere in the world, the problem is particularly prevalent in South Korea.

Hidden cameras and illegal filming are a big problem in South Korea

According to the BBC, between 2013 and 2018, South Korean police received more than 30,000 reports of use of hidden cameras.

In 2021, Human Rights Watch released a report detailing the spread and impact of these "digital sex crimes" in South Korea.

From 2008 to 2017, prosecutions for sex offenses involving unlawful filming increased 11-fold, from 585 to 6,615.

They also accounted for about 20 percent of sex crime prosecutions in 2017, up from 4 percent in 2008.

So if you are one of the many Singaporeans planning to visit South Korea soon, it might be a good idea to invest in a hidden camera detector and mobile signal jammer - better safe than sorry.

 

 

Subodh Yadav, 37, and his accomplice Vipin Kumar, 42, were arrested in the car robbery.

According to police officer Romil Baaniya, the two allegedly confessed to the crime and provided details of their actions.

• New Delhi: An undercover operation has resulted in the arrest of two men for stealing luxury cars in and around the Delhi-NCR area.


• During the arrest, police recovered a cell phone signal blocker and other sophisticated tools that could help read and duplicate the car's ignition and locking systems.


• The defendants used bluetooth jammer to prevent people from calling or texting police from crime scenes to leak information.

Subodh Yadav, 37, and his accomplice Vipin Kumar, 42, were arrested in the car robbery. According to police officer Romil Baaniya, the two allegedly confessed to the crime and provided details of their actions.

Yadav and Kumar allegedly purchased the damaged cars from insurance companies and, through a vast network of engine and chassis number punchers, changed the numbers of the stolen cars to those of the damaged cars. They will then sell the car to a used car buyer. Kumar himself runs an automotive workshop in Chandigarh where he stamps engines and chassis numbers.

The accused, Subodh Kumar Yadav, has more than 20 previous convictions including murder and attempted murder.

The Anti-Auto Theft Squad was alerted to the problem after multiple motor vehicle thefts and began investigating the cases. After gathering intel on the potential automatic elevator behind the crime, they learn of the presence of Subodh Yadav and Vipin Kumar in Vasant Gaon. The informant allegedly told the police that the two would travel to Vasant Gaon to seal another deal for the stolen luxury car.

Based on this information, the team planted a trap near Valmiki Mandir there. Subodh Yadav and Vipin Kumar arrived by car and got off. Sensing something was wrong, the two tried to run away, but the team became alert and they caught both of them.

They discovered that the car they had come in, a Mahindra Rexton, had also been stolen.

In addition to the mobile jammers, police also recovered six stolen vehicles, including a Honda City and a Honda Amaze, as well as keys to 20 different cars and other tools they used to successfully steal the vehicles.

The Delhi High Court is hearing pleas against the prison authority

1. Which has been accused of engaging in various illegal activities such as extorting money, supplying drugs, mobile phones and other prohibited items.




2. Prison authorities informed the Delhi High Court on Tuesday that mobile signals, especially those of Jio 4G, cannot be blocked inside Tihar Jail using the technology they have, and have asked state-run C-DOT to develop a prototype car gps jammer to prevent inmates.




3. The court is hearing a Public Interest Litigation (PIL) filed by a lifer inmate after receiving a letter from him accusing prison authorities of being involved in various illegal activities such as extorting money and supplying drugs, mobile phones and other prohibited items.

It further alleged that prisoners were "tortured like animals" by prison authorities. After receiving the letter in 2018, the court has asked a prison visiting judge to investigate the allegations and submit a report.

In his April 2019 report, the judge informed the court that the allegations that prohibited items were found inside the prison and that prison authorities extorted money from prisoners for the fundamental right of one hour a day of release were based on statements by various prisoners.

A few years ago, a Florida man was fined $48,000 by the FCC for using an illegal signal jammer during his commute to stop nearby drivers from using their phones.

I can understand. I bet you can too.

1. In California and at least a dozen other states, it's illegal to drive with a cell phone in your hand. But that doesn't stop people from doing it.




2. Every day comes across careless, self-righteous fools who endanger themselves and those around them by chatting or texting on the road.




3. That's why I'm calling on the auto industry to install signal-jamming technology on steering wheels so drivers (not passengers) can't succumb to the temptation to play with their gadgets while driving 3,000 pounds of steel at 60 mph for an hour.

Admittedly, things are complicated.

• "If parents have the option to get their kids off the ground and developing safe driving habits, there could be real safety benefits," said Rosemary Shahan, president of Consumers for Auto Reliability and Safety, a Sacramento-based advocacy group. .




• "But if it's conceived as a way to change the behavior of all drivers, it seems unlikely that those who are the worst offenders when it comes to cell phone use will be inclined to buy the option," she told me.




• If such technology is mandatory, Shahan observes, "in an emergency, what about calling 911 in an unsafe situation, or using your phone to navigate or get directions?"

These are big questions. But we face a big problem.

The National Highway Traffic Safety Administration says 37,133 people were killed in motor vehicle crashes last year, with more than 3,000 of those deaths from distracted driving. Thousands of people are injured each year when drivers take their eyes off the road.

I reached out to the Alliance of Automobile Manufacturers, an industry group, to find out where the automakers stand. Brian Goodman, spokesman for the group, said the automaker takes the matter seriously.

"We can all agree that hands on the wheel and eyes on the road are still key to safe driving," he said, adding that phones "were never designed to be used while driving."

But Goodman insists there is only so much the industry can do. He emailed me a link to the FCC page that addresses the issue.

It said, "Federal law prohibits the operation, marketing, or sale of jammer devices of any type, including cellular and personal communications services (PCS), police radar, global positioning systems (GPS), and wireless network services (Wi-Fi).

The FCC states clearly, "These devices pose a serious risk to critical public safety communications and may prevent you and others from making 911 and other emergency calls. Jammers also interfere with law enforcement communications."

"Jamming devices poses a serious security risk," P. Michele Ellison, director of the agency's enforcement bureau, said in a statement on the website. "Over the coming weeks and months, we will intensify our efforts by working with law enforcement to target those who continue to break the law. It's there.

However, the FCC was wrong.

The agency lives in a world where low-power signal jammers might have a range of about 30 feet, while more advanced equipment can block all transmissions the size of a football field. These obviously raise public safety concerns.

But what if small-scale jamming technology could be mounted on the steering wheel with a range of just a few inches-not enough to affect surrounding vehicles, or even other occupants in the car, but enough to prevent drivers from being stupid?

What if the technology was flexible enough not to interfere with medical cell phone jamming device like pacemakers or insulin pumps? Or streaming music services?

What if the most important thing is that it doesn't interfere with law enforcement or emergency calls?

"It can be done," said Todd Humphreys, an associate professor of engineering at UT Austin. "Properly calibrated, the interference was strong enough to overwhelm a driver's cell phone near the steering wheel, but not enough to overwhelm a passenger's cell phone."

He said the gsm jammer could use an algorithm to adjust its output based on changes in cell signal strength as the vehicle moves, so the jamming field remains consistent.

However, the human element is always present.

Humphreys correctly points out that some knuckle-dragging drivers (my word, not his) will try to avoid the jamming field by keeping their phones at an arm's length or leaning back in their seats.

"This could lead to a situation that is more dangerous than what we are trying to prevent," he said.

T. Charles Clancy, executive director of Virginia Tech's Hume Center for National Security and Technology, thinks the same.

"If you're texting and driving right now, you're going to use whatever wingspan you have to get around jamming technology," he said.

The trick, says A. Lee Swindlehurst, a professor of electrical engineering and computer science at the University of California, Irvine, is "finding the sweet spot where only the driver's device is disturbed," no matter where he or she puts the phone.

It's technically possible, he said, "but it would be a challenging design."

Maybe we don't want to go the interference route. Perhaps instead, we equip all phones with gps jamming device that don't allow texting if their sensors and cameras detect motion, or if they see the user quickly raising and lowering their eyes while driving.

It may also be feasible to develop jamming techniques that block incoming signals but not outgoing calls, which would solve the problem in emergencies, said Marwan Krunz, a professor of electrical and computer engineering at the University of Arizona.

The point is that there are possible solutions as long as federal authorities are willing to change.

No one at the FCC responded to my repeated requests for comment.

The Floridian who was fined $48,000 has apparently been jamming people's cell phones on the highway for several years. He was charged with "using an illegal device" and told to stop.

Be bold, though.

More people die each year from distracted driving than were killed in the September 11 terrorist attacks. This should indicate that we have a major public safety threat on hand.

Doing nothing should not be an option.

The mobile phone jammer can block various frequencies. The equipment is usually divided into low-end and high-end types. High-end jammers block all frequencies at once, while low-end jammers block only one frequency. Let's take a look at the three subcircuits of a cell phone jammer. If you're considering buying one, it's worth knowing the differences between the three devices.

Low-end jammers only block one frequency at a time

• High-end cell phone jammers block multiple frequencies at once, while low-end models block only one frequency.


• These low-end jammers are usually much smaller and can fit in the palm of your hand.


• They only block one frequency at a time and are less expensive than their higher-end counterparts.


• They also only cover a small area. They can significantly reduce cell phone calls compared to high-end jammers.

range of cell phone jammers

Cell phone jammers range from low-power personal jammers to large devices that create blind spots up to a mile long. The power of the jammer will also depend on its location. Hills and buildings block the signal, so low powered devices may only interfere with calls within 30 feet. But higher powered models were able to create a cell-free zone the size of a football field. Jammers are designed to interfere with digital and analog mobile phones.

To interfere with cell phone signals, it is important to use equipment that operates on the correct frequency. Different cellular systems use different frequencies and therefore have different ranges for interfering devices. GSM uses the 900 MHz frequency band in Europe and Asia and 1900 MHz in the US. But there are jammers that work on all frequencies and these devices are equally effective on GSM, PCS and Nextel systems. A jammer that blocks analog cell phone signals is just as susceptible to interference as its counterparts.

signal strength for gsm blocker

A cell phone signal blocker is a device that blocks cell phone signal reception. It can be used to deter or stop espionage by detecting its signature. Signal blockers are generally box-type, with a single output power of 15W. Such devices are segmented to only interfere with the downlink. Its soft start circuit design prevents sparking and provides good working stability.

transmission power of gsm interceptor

A gsm blocker is an electronic device that blocks signals from mobile phones. The device transmits at a lower power level than other mobile devices to protect the human body and reduce interference. This power level is regulated by local regulators. Depending on the type of equipment used, the power level can range from zero to a few dB or more. However, these factors can only be used to determine the effectiveness of the device.

distance between base station and gsm blocker

The distance between the base station and the phone is key to successfully jamming the signal. There are two main types of signals: SMS and ortungscodes. While SMS are an alternative to signaling channels, they are less efficient. The two types of signals have different amounts of information, and the distance between the base station and the phone is usually greater. To prevent interference, the phone should be placed 200 to 300 meters from the base station.

A cell phone jammer works similar to a home stereo. Signals are sent from cell phones to cell towers, which distribute the workload to specific areas. The jamming device is placed between the two towers and simulates cell phone signals by sending radio frequencies to the same frequencies as cell phones. Unlike a phone signal, this one is strong enough to block the signal.

High-end jammer blocks all frequencies at once

Cell phone jammers are powerful devices that interfere with wireless signal transmissions. These devices work by simulating legitimate phone signals on the same frequency as cell phones, preventing them from making or receiving calls. Jammers operate on different frequencies, and some of them block all jammers at once. They are a great solution for individuals who want to eliminate annoying prank calls and avoid being harassed.

High-end devices are capable of completely blocking multiple cellular networks at once. The best jammers are able to block several different frequencies at once, which makes them very effective against both the cell phone network and the caller. Some models can even be programmed to jam specific frequencies. High-end jammers will be able to block all frequencies at once and can also jam dual or triple mode phones.

Cell phones are wonderful communication tools, but sometimes people misuse them in inappropriate ways. They don't always put them away when they're out in public, or they ignore signs that say they shouldn't be used. A cell phone can even be used as an improvised explosive device, a device that can destroy buildings, cars and even other people. IED jammers can help prevent these attacks and save lives.

Here are some reasons to consider interfering with your phone in public:

It is not illegal to sell, use or modify mobile phone jammers. They are harder to catch. The only reason they are illegal is because most people are selfish and stupid. But that doesn't mean they're useless. Also, you might be surprised to learn that cell phone jammers can be used for both good and bad. These devices work in a variety of ways and can be used to protect you and your family from cellular communications.

Cell phone interference is banned in many countries, but it is allowed in some circumstances. India, for example, has approved the use of signal blocker in mosques, concert venues and schools. However, they must be used with special authorization. In addition, jammers should only be used where safety and security requirements are strict. That makes sense for the safety of law enforcement officers, but it may not make sense for people trying to block cell phone signals.

If you are traveling and receive frequent unwanted calls, you may want to consider using a signal blocker. These devices can block signals and prevent people trying to spy on you from contacting you. The downside to these devices is that they may interfere with your call reception. In addition, you may come into contact with keyloggers transmitted over public Wi-Fi signals. These devices are not for everyone.

They block cellular data

If you're on a crowded train or worried about cell phone users yelling at you, it might be time to try a cell phone blocker. These devices are useful in many situations, including movie theaters or schools. They also work well on vehicles and other quiet trains. Depending on the type of jammer you buy, they can shut down service up to a mile away.

They interfere with GPS

Having your phone in the background all the time, such as in a pocket or bag, can interfere with your GPS and render it unusable. If you want to avoid being followed while driving, it's best to avoid these situations. gps jamming is illegal in the UK, and if caught, you could be hit with a $16,000 fine. Using a phone jammer to interfere with GPS signals is dangerous and illegal in most countries.

They interfere with WiFi

Have you ever experienced interruptions or intermittent WiFi when using a wireless network? If so, you're not alone. Wi-Fi networks can be affected by adjacent power cables, improperly shielded cables, and external monitors. You can also use a free application called NetSpot to see the signal strength of your wireless network and determine if it is being interfered with. Depending on the cause of the interference, it could be your wireless card or an outdated driver.

They can be used to deter corporate espionage

Companies should be more vigilant about corporate espionage than identity theft. These spies may steal confidential information about your company or request federal government documents to gain access to your files. It can also make your company vulnerable to freelance espionage. In addition, admitting that your company is threatened by espionage may undermine shareholder confidence and attract freelancers. Similarly, a corporate security breach may cause your stock price to drop.

The cost of cell phone jammers

Cell phone blocker is a device that blocks cell phone signals. The devices could be used in prisons, public places and educational institutions to deter cheaters and limit mobile phone use. These devices block cellular and CDMA phone signals. The cost of cell phone jammers varies depending on the spectrum used by the country/region. Some jammers work on one band, while others work on both.

There are many places to install a signal jammer. These include theaters, classrooms, vehicles, and other quiet trains. Cell phones can be extremely destructive and dangerous, so you may want to consider buying one. However, it is important to understand that the device is not cheap and is an investment. It is important to study the cost of jammers before making a final decision. Fortunately, there are many different types of jammers available for sale, and the cost of each will depend on the capabilities of your device.

Do you still remember the good times when we didn't have smartphones? How do we communicate with each other? Okay, we always have face-to-face conversations or write letters. Now let's take a look at the phone screen. Various social apps are flooding our lives. We take photos every day, upload them to Facebook, or learn about what others are doing. Of course, it is common to use mobile phones in classrooms, as well as ringing tones in restaurants, theaters, and churches.

Undoubtedly, most offices require internet access, but what about mobile phones? After some research, we found that 50% of managers believe that using mobile phones in the workplace is not good. Using a mobile phone at work can distract your attention. This is why some manufacturers that prohibit the use of mobile phones have abnormally high productivity. Therefore, you should consider using a signal blocker to block signals in order to improve employee work efficiency. We need to take specific measures to make mobile phone usage healthier and more standardized. cell phone jammer have changed the way phones are used.

There are many reasons to purchase a wifi blocker. They not only protect your WiFi network, but also help you track the surrounding environment. With so many types to choose from, it may be difficult to find a type that effectively prevents everyone from entering.

Mobile GPS 5G WIFI signal blocker

The mobile GPS 5G WIFI signal blocker is an important device to prevent receiving wireless signals. Its high output power (up to 30 W per channel) will block the signal used by the phone. The jammer is very powerful and can block signals from any type of mobile phone within a radius of 30 meters. It also has an intelligent cooling system, with 11 cooling fans in the device, four of which are located at the top. The jammer can control the shielding range of the casing through its built-in power setting. Its uninterrupted operation will last for 7 days, and its high output power ensures that users are not affected by any interference from mobile phone signals.

In addition to blocking mobile phone signals, jammers can also block a wide range of other wireless signals. Some popular signal blocker models include Bluetooth, UHF VHF, and 3G/4G frequency bands. These devices are made using the latest technology and can block GPS signals, while being small enough to be hidden in pockets or bags. This multifunctional signal jammer is a portable device that helps you stay away from the dangers of wireless communication.

Here are some common answers to questions about mobile phone jammers.

• 1. Why do I still receive a complete bar signal during the operation of the signal shield?




It takes approximately 30 seconds for the signal shield to completely shield it. Afterwards, your phone will not be able to be dialed or called. This is the question that our clients ask the most. They realized that their phone was displaying false signals.




• 2. Will signal shields affect the operation of other devices?




The signal is relatively stationary and will not interfere with other electronic devices. Most mobile phone blockers not only block phone signals, but also have the function of simultaneously blocking WiFi, Bluetooth, or GPS. If not needed, you can simply remove the antennas to disable them.




• 3. Are signal shields harmful to human health?




You can be certain. The electromagnetic signal strength of the jammer is very weak. The signal strength is harmless to the human body. At the same time, the mobile signal blocker can only block the input signal of the phone, and the phone cannot communicate with the base station, which will not damage the phone.

Is the distance between the internal and external WiFi blockers of the phone different?

Of course, the effective distance of GPS jammers phone signals usually refers to the internal distance. Whether indoors or outdoors, the interference range of the effective shielding distance depends on the environment, such as the distance to the base station and the installation location.

If you are searching for mobile signal blockers online, you may want to know the legality, price, and how to purchase them in the United States.

Legitimacy of Mobile Phone Jammer in the United States

A recent case involving the legality of mobile phone jammers in the United States resulted in a Dallas company being fined $22000. This device is designed to interfere with wireless communication, including 911 and maritime and aviation communication. Unable to authenticate the device and does not comply with FCC technical standards. Therefore, selling or manufacturing these devices is illegal. However, there are also some exceptions to these rules.

The recent case involving two companies accused of illegally manufacturing and selling jammers is a good example. In one case, an electronic product manufacturer named RNM was found using cell phone blocker in their workplace. The FCC imposed a fine of $17000 on the company, plus $5000 for "bad behavior". Ravi's Import Warehouse received a notice of violation and requested the FCC Bureau to reconsider the decision. The FCC's law enforcement department rejected the request for reconsideration based on the company's compliance history.

The cost of mobile phone jammers

If you are looking for a phone jammer, you can find many options online. Many jammers aim to block one or more channels. More expensive models can block multiple signals simultaneously. You can also purchase a cheaper single channel blocker for only one signal. The cheaper models use battery power and can only cover very small areas. They are not as powerful as high-end devices, but they can still help you get rid of phone calls.

Before purchasing a mobile signal blocker, be sure to conduct some investigation. Firstly, you need to check the manufacturer. Find someone who uses three watts of power. Ensure that the jammer is suitable for all major networks. This will ensure that you receive the best value for money product. If you are worried about attracting thieves, please consider investing in a device that can block signals.

Does the endless thump of your neighbor's music drive you nuts? We've been there. Sound can be the most frustrating thing that prevents people from getting a good night's sleep, as it's often difficult to control. For sensitive sleepers, noise can be one of the biggest obstacles to a good night's sleep-even when the noise comes from an understandable source.

Thoughtful family members and roommates will often refuse to watch TV if asked politely. But it's not easy to stop falling asleep to the noise of your neighbor's all-night party. I'm not suggesting that you give up trying to stop the noise at the source if you can. However, sometimes it is more productive to focus on reducing the amount of noise entering the brain when other people are controlling the source of the noise. It's always going to be tough, though, which is the main reason we recommend signal blocker.

One of the many sleep problems older adults experience throughout their lives. Long-term, chronic sleep disorders affect approximately 40 million Americans. Whether your loved one has Alzheimer's or depression, noise syndrome can be a disorder experienced by older adults that leaves them restless throughout the day. Symptoms of this condition usually occur in the late afternoon and evening. Not only can it cause your loved one to have trouble sleeping at night, but it can also lead to behavioral problems. Because of this condition, the home caregiver may experience sleep deprivation, so you may need the home caregiver to assist with care work, including monitoring the elderly at night.

And nothing looks more peaceful than a sleeping child. But even as they curl up in bed, their brains are hard at work with developmental activities like memory consolidation (the process of collating experiences, learning what's important and letting go of what's not).

"[Sleep] is critical for everyone, but especially for children who are developing both physically and mentally," says Dr. Sumit Bhargava, director of the Sleep Center for Healthy Children at Stanford. "We're learning more and more about the effects of sleep on regulating hormones. For example, in children, the period of strongest growth hormone release is shortly after the onset of deep sleep."

Noisy Environments May Also Cause Sleep Disturbances

Dr. Sumit Bhargava recommends keeping your child's room ZZZ-friendly by keeping lighting low and temperatures around 70 degrees Fahrenheit or 21.11 degrees Celsius. If noise is unavoidable, try a white noise or pink noise machine to block out some of the sound.

You may not be able to create a "noise-free" environment for your baby.

So how can you help your baby get a good night's sleep when things get a little rowdy?

A generally quiet bedroom is a sign of a good sleeping environment. Some toddlers are very sensitive to sound, and once you put her to sleep, you may find yourself walking around cautiously! One thing you can do is introduce positive white noise, such as a sound machine, box fan, or lullabies. These also block out general household noise, making it easier for your child to fall asleep.

Therefore, sleep is very important, especially for children. Sadly, just knowing your child needs a good night's sleep doesn't mean they'll get it

• 
  

  One of the most important parts of sleep hygiene is routine. When you think of routine, time and place come to mind, but sound should also be included. Sleeping should be the same every night, and white noise helps with the audio portion of this routine. It will create a unique sound environment for your child, soothe them and give them a good night's sleep.



• 
  

  If your child is having a hard time at night, it's important to figure out whether it's the noise or the nightmare.



• 
  

  If your child had nightmares or didn't sleep well the night before, you can ask them about it in the morning. If they can talk about a nightmare, you can help them come up with some alternate ending or some other imagery instead of focusing. Explain to them that nightmares are a product of their imagination and reassure them that they are safe. Sleepwalking and night terrors occur during slow-wave sleep. They occur in the first third of the sleep cycle, and the dreamer does not remember them.

This step is arguably the more dramatic one, and won't win you any friends: If your neighbors keep getting loud in disrespectful ways, you can call your local authority's noise pollution unit. This varies by country, but may be the only way to handle Sunday morning construction work or constant late night parties. Checking the laws where you live can help you prepare your case. Go online to find out when builders can use power tools, when signal phone jammer can be used, how late music can be played on the street.

Sleep problems tend to create a vicious cycle, and noise is no exception. The stress of being kept awake by the noise can itself become the worry that keeps you awake. This worry can become a reason for not being able to sleep. If the person or object making the sound gets your blood boiling and fills you with anger, that's not conducive to a good night's sleep, either. In short, it's hard to sleep when your head is full of angry thoughts. If you are a sensitive person prone to stress and anxiety, it may not be easy to let go. Try a new approach of forgiving (or at least tolerating) whoever or whatever is making the noise, and using the gps jamming device to fight back.

It works so well that you barely notice him -- not even his expression, not even his facial expression.

Nowadays, mobile phones have become digital products in daily life, and people can communicate through mobile phones at any time. With the development of society, mobile phones will become more and more popular in the future. From this point of view, mobile phone jammers will become more and more popular in the future.

There are many other possibilities for using a cell phone jammer:

for example, an employer may want to avoid conversations in (or around) the office; or you may want to lie on the beach with your family instead of talking over a loudspeaker.

So it's important to understand this. The mobile phone jammer can not only block calls from mobile phones, but also block calls from any other electronic products. Jammers are commonly used by police and military forces to control or interrupt communications in the event of hostage-taking and bomb threats.

Cell phone jammers for sale are very popular in many countries, but their effective range is limited by the coverage area of the network and the strength of the cell phone signal of nearby base stations. So what should I do when I want to take control of my privacy?

1. The main reason people use gps signal jammer is to block the GPS signal, but there are other reasons as well.


2. Some people want to protect their privacy by jamming the satellite navigation systems that monitor them and record their whereabouts.


3. Others buy these devices to keep their phones from being tracked, which can be inconvenient or even dangerous (if you're being tracked, for example).


4. A third reason might be that they don't want to be tracked -- for example, someone who works at an airport might want to prevent airlines from knowing where they go after get off work at night.

As we all know, everyone's life is inseparable from mobile phones. When you are in class or in the office, someone is playing mobile games, making phone calls with others, and disturbing others. To solve this problem, we use a cell phone jammer.

GPS jammer is a device that emits radio signals within the same frequency range as GPS satellites. These devices, known as jammers, may damage or damage the GPS receiver and create dangerous situations in your vehicle. You can use these devices to block GPS, but you should only use them in extreme situations as they may cause serious accidents. The most common use of jammers is to block signals from mobile phones or other electronic devices that track your location. If you want to prevent your employer or government agency from tracking your phone without your knowledge, you can use a gps jamming. When you try to avoid using toll roads or lanes while on vacation, the jammer will also come in handy.

The GPS jammer used for vehicles is usually a small independent frequency transmitter. The GPS jammer is usually a small independent frequency transmitter. This means that GPS jammers can be as small as your phone or larger devices installed in your car or truck.

Before starting to use a GPS jammer, please ensure that it is legal to do so in your country. If using GPS jammers is illegal, the consequences of violating this law are very serious.

In addition to knowing what is legal and what is not, there are other things you should know before using a GPS jammer.

• How does it work? What is its transmission frequency?


• How much power does it consume? When should I close or reopen it?


• Who can hear my voice when I use a GPS jammer (phone jammer)? Can they use a mobile tracking application to track my location?

How long will GPS tracker jammers affect signal quality?

The GPS signal jammer interferes with the GPS signal, usually a small independent frequency transmitter. This device must be manually turned on and off, but it can be used to block GPS signals of specific frequencies.

They are usually used to prevent conversations from being overheard by others or to prevent phone calls from being made in disallowed places such as cinemas. In some countries/regions, there are laws prohibiting their use. In most cases, these blockers can block any type of GSM phone signal, including 2G, 3G, 4G LTE, etc., depending on the model you purchased.

High power signal blocker is a unique device that can prevent mobile phones from receiving signals from base stations. They are usually used by the police and military to control communication during hostage taking and bomb threats.

But there are many other possibilities for using mobile phone jammers: for example, employers may want to avoid conversations in the office (or around); Or you may want to lie on the beach with your family instead of talking through a loudspeaker.

Therefore, it is important to understand this. Mobile phone gsm blocker can not only block calls from mobile phones, but also block calls from any other electronic product.

 

Can signal blocker really block all signals?

Although the time for the college entrance examination has indeed been delayed due to the pandemic in recent times, corresponding measures have not been reduced in order to ensure the safety of the examination room details. Operators have actually released news one after another. During the exam, according to the needs of the Education Bureau, the cordless signal wifi blocker will definitely be turned on, which will inevitably affect the interaction quality of mobile phone users throughout the school. Communication will not return to normal until the end of the test. What are the characteristics of the signal blocking device for the entire process of the college entrance examination? The invigilator at the entrance of the examination room waved a metal detector. Is it really useful?

To understand the function of blocking mobile phone signals, let's first understand how mobile communication works.

As a mobile communication tool, mobile phones need to first establish a link with nearby base stations, and then connect to the core network to discover interactive destinations. In the above process, all information is carried and transmitted by electromagnetic waves. The frequency band of electromagnetic waves used in mobile phones is related to the requirements of the phone and the operator. But overall, the electromagnetic wave patterns used by the three major operators are distributed in the frequency range of 850-4900MHz. If the organizer of the college entrance examination wants to block the mobile phone signal inside the examination room, the 2G/3G/4G/5G base station near the evaluation room cannot be disabled, otherwise all communication devices in this area will not have the ability to connect normally. This is the only way to block mobile phone signals in the exam area.

High power mobile phone jammer, also known as mobile radio signal jammers, are types of devices used to disperse and interfere with almost all incoming signals from relevant network service providers, so only certain devices have resistance to this, most of which are unlikely to be encountered by you no matter what. A high-power mobile phone blocker is an electronic device that can block mobile phone signals within a specific radius range. A high-power mobile phone blocker is an electronic device that can block mobile phone signals within a specific radius range. It blocks high range signals. It is very simple to use to block movement signals. High power mobile phone blockers can block signals up to 40 meters long.

When it comes to blocking smartphone signals, the first thing that comes to mind is metal reinforcement, which means placing the phone in a closed steel box and using steel to block the spread of electromagnetic waves. However, it is clearly unwise to set all levels of the evaluation area to metal enclosed levels. So what should we do? It's very simple, just a small mobile signal gsm blocker is needed to block all smartphone signals in the exam room.

The smartphone signal blocker checks the RF frequency band of the forward channel (base station to mobile phone network) at a certain speed throughout the entire working process, causing interference during the process of obtaining messages through the smartphone signal, ensuring that the smartphone cannot detect signals from the base station. Typical data transmission makes it impossible to establish a link with the base station, and there is also a state of no signal or solution. For example, when a mobile phone interacts with a base station, the signal blocker acts like an instigator, deliberately making sounds around you. The sound signal is too loud, and the phone cannot hear what the base station is saying, nor can the base station hear what the phone is saying.

At present, the mobile signal blockers used in the evaluation area are in the regular frequency band, which can block all the 2G/3G/4G/5G frequency bands of operators, as well as all Wi Fi and Bluetooth signals. The above is the concept of a mobile phone signal gps blocker. However, the frequency range of electromagnetic waves ranges from a few Hz to hundreds of GHz, and each segment can be used as a signal for interaction. Will the evaluation room use some special regular frequency bands? This applies to various other radio communication tools, as well as radio interaction devices with fixed frequency bands that have emerged in this situation. The operating frequency band of these devices is selected outside the regular array covered by the mobile phone jammer,

For this special radio communication equipment, the assessment room is equipped with a monitoring vehicle equipped with a radio display for real-time monitoring of unknown radio wave signals. So how precise is the function of a radio detector?

1. Due to the characteristic of electromagnetic waves being "large in the near and small in the far", by constantly moving the detection vehicle, tracking tools can locate the signal transmitter based on the distance and signal strength, and catch violators using these radio interaction tools on the spot.


2. Nowadays, drones have truly appeared in the college entrance examination area, allowing for faster signal delivery.

 

There are actually several reasons why someone may want to use a signal jammer. For example, services can use them to prevent employees from accessing the internet or using their phones during working hours. The military and police can use them to prevent terrorists and even scammers from communicating during missions. People may use them to block excessive phone calls and even prevent drones from flying over their location.

Although signal jammers pose risks, they may be beneficial in certain situations. For example, they can be used to avoid drones flying over limited locations, such as military bases or personal property. They can also be easily used to avoid unnecessary phone calls or message messages from telemarketers and fraudsters.

A jamming device is actually a device used to interrupt or even block wireless communication signals, including Wi Fi, mobile phones, and GPS signals. Its working principle is to emit radio surges of the same frequency as the target signal, effectively suppressing it and making it meaningless. Although signal jammers can easily come into play in certain situations, they can also be illegal, unsafe, and even fully utilized.

The form of signal jammer equipment

There are actually many types of jammer devices on the market, each with its own characteristics and functions. The most popular type of signal jammer is actually handheld devices, which are very small and easy to move, and can also be used to interfere with signals in specific areas. Another type is computer jammer, which is actually developed to handle larger areas and can be used in buildings, classrooms, and even conference rooms. In fact, there are also in car jammers that can be used to block signals from moving cars, trucks, or vehicles.

• 3. Wi Fi jammer: wifi jamming are actually designed to interrupt Wi Fi signals, preventing devices from connecting to the network through Wi Fi.


• 4.Bluetooth jammer: Bluetooth jammers are created to disrupt Bluetooth signals and prevent devices from connecting to each other through Bluetooth.

A signal jammer is actually a device used to interrupt or block wireless interactive signals (including Wi Fi, mobile, and GPS signals). Its working principle is to emit radio transmissions at exactly the same frequency as the target signal, effectively overturning it and rendering it unusable. Although signal jammers may be practical under specific conditions, they may actually be fully utilized in other illegal and potentially risky ways.

In fact, there may be multiple reasons why someone may intend to use signal jammers. For example, companies can use all of these to prevent employees from accessing the internet or using their phones during working hours. Armed forces and rule management agencies may use all of these to prevent revolutionaries or criminals from communicating in the program. People may use them to block unnecessary phone calls, and even prevent drones from flying over their mass.

Even if there are hazards associated with signal jammers, they may still be beneficial in certain situations. For example, they can be used to prevent drones from flying over restricted areas, such as military bases or personal property. They can also be used to prevent unwanted phone calls, even text messages from telemarketers and fraudsters.
