The United States used the "Predator" drone to launch anti-tank missiles for the first time in actual combat, creating a precedent for drones to strike the ground. However, they believe jammers can be a useful tool in protecting citizens from all kinds of crime and ensuring the safety of British sovereignty. They worry that these devices will reduce the transparency of government activities and the questionable behavior of political officials, in which mobile communications can be a useful source of evidence in the fight against political crimes. However, British youth and human rights advocates have raised concerns about the proposed widespread use of mobile signal jammer.

These drones have a cruise function, which can not only perform reconnaissance missions but also "change" missile attacks after discovering targets, so they are also called cruise missiles. Savage and pointing out that they were held at the same time as the G8 summit probably had a purpose. Nearly an hour later, a double-decker bus in Upper Woburn Square, near Tavistock Square, was also hit; the bus's roof was knocked off in the blast. British authorities are aware that terrorists have been known to use mobile phones as improvised remote controls to cause explosions.

The UK has made the fight against swarming drones a top priority, exploring ways to use radio frequency suppressors to disrupt the links of swarming drones. As British troops fought alongside coalition forces against Islamic terrorists in Afghanistan and Iraq, they knew what it was like to bomb the militants. There are phone jammers, which are designed to stop a cell phone's remote functionality from causing a terrorist's improvised explosive device (IED) to detonate. Due to the increasing number of mobile phone users, there are also growing concerns such as breaches of privacy and cheating in school exams.

If two drones are used, the drone used for reconnaissance will most likely also carry electronic jamming equipment. A cell phone jammer is basically defined as a device that stops any communication process within a cell phone. The phone signal jammer has been immersed in water or near a fire source. Do not use the jammer in places with high humidity, overheating, high voltage or high radiation. In normal use, the antenna should be perpendicular to the ground to obtain the maximum shielding range. What should be paid attention to when using jammers? All antennas must be tightened before starting work.

The youth and human rights advocate added that cutting off mobile phone communications could take away their freedom of expression because of the huge number of mobile phone users in the UK. Since then, the application of military drones has become more and more extensive, and it has developed towards the integration of inspection and attack, and the integration of attack and defense. To counter these security threats, surveillance drones (MDrs) need to be deployed for surveillance, hunting, and wifi jamming devices from amateur drones (ADr). In addition, in many regional conflicts in recent years, small and medium-sized suicide drones have been put into battle in large numbers.

The attack came as world leaders, including British Prime Minister Tony Blair, were meeting at a Group of Eight summits near Scotland. In another incident in October 2016, two Kurdish soldiers were killed and two Frenchmen were injured when an IS drone exploded after attacking troops. Anti-drone measures in northern Iraq diversify against drones on the battlefield. In recent years, various countries have launched countermeasures. The Russian army regards drone defense operations as an important task and has practiced anti-drone combat technology on the Syrian battlefield. In general, the current main anti-UAV means include electronic jamming interception, artillery missile hard kill, high-energy laser weapons and high-power microwave weapon interception.

However, such functional characteristics are completely different from those of mobile phone signal shielding. Therefore, when this kind of APP software is running, it will not significantly change the original working status and performance of the mobile phone, and the mobile phone itself can communicate with the outside world normally. The mobile phone shows no signal, no network, cannot receive and make calls normally, cannot send and receive text messages and use data traffic, etc. And the usual spy APP software or Trojan horse program, it must first show concealment and deception, so that users cannot quickly find out.

What's more, some people even hope that there is such an APP software that can remotely block the mobile phone signal of a specific mobile phone number. We do not deny that some malicious APP software has the characteristics of spyware, which can steal user information privately and even allow mobile phones to perform basic functions or programs without the user's knowledge. The so-called mobile phone signal shielding means that the mobile phone cannot complete normal communication with the base station at all. That is, the phone is in a state of being completely disconnected from the network.

GPS jammers are also used to disrupt the communications of outlaws and insurgents, which impedes their illegal and violent actions. However, this would increase the likelihood of a collision with a commercial flight, as in April 2016 when British Airways Flight 727 was reported to the Metropolitan Police by what he believed to be a drone that struck his plane. More commonly, the group consists of both reconnaissance and uplink devices. In real life, there is no APP software that can provide the function of shielding mobile phone signals for other people's mobile phones. People making such requests should confuse the functionality of cell phone spyware or Trojan horse programs with cell phone signal-blocking capabilities.
