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.




The most popular 8 band jammers

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.




Desktop  Jammers

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.

In today's world, isolation is very difficult. The internet keeps us updated; We follow news on Twitter and Facebook; It is easy to obtain TV programs through DVR and on-demand services. Although our access to information enhances our ability to live in a globally connected world, information is always available. Unfortunately, this also means that people are often distracted by information. One of the biggest disruptions in the 21st century is mobile phones. In class, a random phone call or text message may cause all students to lose concentration - their grades may also decrease; If you are traveling, phone conversations and other activities may slow down or hinder your progress; Silence is necessary for worship - but today, its jammer phone is a device that blocks the reception of phone signals, preventing the use of wireless devices such as smartphones and smartphones.


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.




Power Adjustable Jammer

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.




Blocker CDMA GSM 3G 4G

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.

Discontent is a significant factor in the growth of individuals, communities, and civilization. Excessive dissatisfaction may have negative consequences, but an appropriate level of discontent can bring about positive outcomes. If everyone is content with the status quo, progress will stagnate, leading to the decline of humanity. In this article, we will present the necessity of discontent in the creation of cell phone signal jammers.


The primary purpose of a cell phone jammers is to effectively obstruct unauthorized communication signals whenever necessary. This device is particularly well-suited for individuals employed in diverse government and correctional institutions. However, it is important to note that signal jammers have the capability to impede communications, posing a significant security risk.


Security is a crucial requirement for certain facilities due to clear reasons. Take military facilities, for instance, where communication is strictly regulated and requires prior approval.


Cell phones play an important role in our daily life. Why are there cell phone blockers now? Dissatisfaction is dissatisfaction, dissatisfaction with the improper use of mobile phones in some formal occasions. Discontent is also a driving force of human civilization as a whole. It can be said that in primitive society, science came into being because ancestors were not satisfied with their understanding of the world, and technology came into being because ancestors were not satisfied with simple manual labor. This curiosity and desire, in fact, also led to the prosperity of technology later.


Use jammers to prevent interference and block unauthorized communications


In order to avoid disruptions, it is essential to utilize a signal jammer to enhance your daily life. Several nations prohibit the use of cell phone jammers by individuals. It is important to verify the regulations in your area. Some people opt to install jammers, particularly cell phone jammers, to prevent disturbances. If it is permissible under your country's laws, you may acquire a beneficial jamming device.


In various settings such as classrooms, conference rooms, presentations, or religious services, receiving a call at an inappropriate moment can lead to significant disruptions. However, the use of cell phone jammers can effectively prevent such calls from occurring in the first place. By employing these devices, interference and unwanted phone noise can be blocked, granting you the ability to regain control over the situation.


Encountered this scenario before? The phone kept ringing, yet no one bothered to address the disturbance. You vocalize, "Kindly silence your phone." Unfortunately, your call goes unanswered. In a large gathering, instructing individuals to silence their devices proves ineffective. A considerable portion will inevitably keep their devices active for various reasons. The solution? A cell phone jammer.


It is a matter of debate whether this signifies a broader issue within society, nevertheless, it remains a fact. Even during solemn occasions like funerals, it is unavoidable that there will be intermittent phone calls to disrupt the silence or offer prayers.


The signal jammer has the capability to disrupt the frequency required for a phone to receive incoming calls, regardless of the circumstances, resulting in the phone not ringing.
