A Cell phone jammer gps is basically defined as a device that stops any communication process within phones. Due to the rising number of mobile phone subscribers, there are also rising concerns such as breach of privacy and cheating at tests in schools. Jammers are also use to disrupt communications by outlaws and rebels, which hampers their illegal and violent operations. There are phone jammers that are designed to stop the remote capabilities of mobile phones from causing improvised explosive device (IED) explosions by terrorists.

Since the British troops have fought alongside the coalition forces in wars against Islamist terrorists in Afghanistan and Iraq, they are aware of the bombing capabilities of the militants. British authorities know that terrorists are known to use mobile phones as improvised remote controls to cause explosions.

On the morning of July 7, 2005, bombs are detonated in three crowded London subways and one bus during the peak of the city’s rush hour. The synchronized suicide bombings, which were thought to be the work of al-Qaida, killed 56 people including the bombers and injured another 700. It was the largest attack on Great Britain since World War II. No warning was given.

The train bombings targeted the London Underground, the city’s subway system. Nearly simultaneous explosions, at about 8:50 a.m., occurred on trains in three locations: between the Aldgate and Liverpool Street stations on the Circle Line; between the Russell Square and King’s Cross stations on the Piccadilly Line; and at the Edgware Road station, also on the Circle Line. Almost an hour later, a double-decker bus on Upper Woburn Place near Tavistock Square was also hit; the bus’s roof was ripped off by the blast.

The attacks took place as world leaders, including British Prime Minister Tony Blair, were meeting at the G8 summit in nearby Scotland. In his remarks after learning of the blasts, Blair called the attacks barbaric and pointed out that their taking place at the same time as the G8 summit was most likely purposeful. Later, he vowed to see those responsible brought to justice and that Great Britain, a major partner with the U.S. in the war in Iraq, would not be intimidated by terrorists.

Since the July 7, 2005 bus bombings in London, law enforcement agencies all over the country has sought a need for jammers to keep prisoners from making communications that could lead to their escape. However, the British youth and human rights advocates express their concerns on the proposed widespread use of mobile signal jammer.They fear that the devices could lower the transparency on government activities and suspicious doings by political officials, wherein mobile communication can become useful sources of evidence in fighting political crimes. The youth and human rights promoters add that cutting off mobile phone communications can deprive them of freedom of expression, since Great Britain has a huge population of mobile phone subscribers.

As of now, the British government is taking consideration on the use of jammers in UK prisons. However, they believe that jammers can become a useful tool to protect citizens from various crimes and ensure the security of Britain’s sovereignty. Hopefully when these things are used wisely, British authorities can become heroes of the modern society.

In real life, no APP software can provide the function of blocking mobile phone signals for other people’s mobile phones.

The person who made such a request should have confused the function of mobile phone spyware or Trojan horse program with the function of mobile phone signal jammers.

We do not deny that some malicious APP software has the characteristics of spyware, which can steal user information privately and even let the mobile phone execute basic functions or programs without the user’s awareness.

However, such functional features are completely different from the functional features of cell phone signal shielding.

The so-called mobile phone signal shielding means that the mobile phone cannot complete normal communication with the base station at all. The mobile phone shows no signal, no network, cannot answer and make calls normally, cannot send and receive text messages and use data traffic, etc. That is to say, the mobile phone is in a state of being completely disconnected from the network.

And the usual spy APP software or Trojan horse program, it must first show concealment and deceptiveness, so that users cannot find it quickly. Therefore, when this type of APP software works, the original working state and performance of the mobile phone will not be significantly changed, and the mobile phone itself can also communicate normally with the outside world.

What’s more, some people even hope that there is such an APP software that can remotely block the mobile phone signal for a specific mobile phone number. Such functional requirements are even more outrageous and unreasonable.

What should I pay attention to when using the jammer?

All antennas must be screwed on before starting work.

Under normal use, the antenna should be perpendicular to the ground to obtain the maximum shielding range.

Do not put the hand-held mobile phone signal jammer into water or close to the fire source, and do not use the jammers gps in places with excessive humidity, overheating, high voltage or high radiation.

In 2001, 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. Since then, the application of military UAVs has become more and more extensive, and it has developed towards the integration of inspection and attack, and the integration of attack and defense. According to a statistical data from the Stockholm International Peace Research Institute, from 1980 to 2020, there were 43 types of UAVs in the international market, including 35 types of large and medium-sized, long-endurance and fixed-wing combat UAVs, accounting for 82% of the total.

To counter these security threats, surveillance drones (MDrs) need to be deployed for surveillance, hunting, and wifi jamming equipment from amateur drones (ADr). If there are three cell phone jammer in the group, the first is for 1-1.5 km altitude reconnaissance, the second is for electronic warfare, and the third is a transponder that transmits intelligence information to the control center (it flies at an altitude of 4.5- 5 km or higher).

Hezbollah has integrated tiny drones into their arsenal and is using them to drop munitions on rebels in northern Syria (AMN, 9 August 2016).

In addition, in many regional conflicts in recent years, small and medium-sized suicide drones have been put into combat in large numbers. These drones have the function of cruising, which can not only perform reconnaissance missions, but also “change” missiles to attack after finding the target, so they are also called cruising missiles.

In another incident in October 2016, two Kurdish soldiers were killed and two Frenchmen injured when an IS drone exploded after it struck troops in northern Iraq. Interestingly, some of these U.S. counter-drone tactics are particularly reminiscent of al-Qaeda’s response to U.S. drone strikes, as reflected in recovered al-Qaeda internal documents and observed behavior.

This signal jammers effort was designed to build on Hezbollah’s successful September 2014 drone strike that killed an estimated 23 “Syrian rebels” (Remote Control Project, January 2016: 11).

　　Diversification of anti-drone means

In view of the threat posed by drones on the battlefield, countries have launched countermeasures in recent years. The U.S. military ranks drones as one of the most destructive aerial threats and has developed a “Counter-UAV System Strategy” to deal with it. The Russian military has listed UAV defense operations as an important task, and practiced anti-UAV combat technology on the Syrian battlefield. The UK has made countering swarm drones a top priority, exploring ways to use radio frequency suppressors to disrupt swarm drone links.

In general, the current main anti-UAV means include electronic interference blocking, artillery missile hard kill, high-energy laser weapons and high-power microwave weapons interception.

According to the U.S. Federal Aviation Administration (FAA), pilots of commercial airlines have reported more than 100 emergency calls or drones in the vicinity of aircraft visible at airports. Drone sales are expected to cross the 140,000-unit mark in 2016, a 50 percent increase over 2015 sales. However, it would increase the chance of a collision with a commercial flight, as in April 2016 British Airways flight 727 reported to the Met police that he believed a drone had hit his plane.

More commonly, the group consists of two devices for reconnaissance and uplink. If two drones are used, the drone used for reconnaissance is likely to also carry electronic jammer gps equipment, ATO headquarters said.

In recent years, traditional security system protection is mainly aimed at ground threats, resulting in increasingly prominent threats and harassment from air targets.

For drones that are in an illegal flying state, they need to be reversed through detection and identification technology. At present, the drone GPS jammers mainly adopts four countermeasures.

Intercept capture class

Another countermeasure is interception and capture from the ground or air. The main methods are: nets, drones, eagles, etc. The use of launchers to catapult nets is more common, but this method has limited range for drones. In addition, large drones are used to capture small drones, large 8-axis drones are used to capture small drones, and there is a huge capture net below.

However, this method is difficult to control, and small UAVs have advantages in flexibility, so they have not been widely used. Also, by training eagles, drones are captured and brought to designated areas. In order to intercept and capture drones, drones need to be within visual range, so their range is very limited. With the development of UAV obstacle avoidance technology, interception and capture will become more and more difficult.

bait control

Navigation signal decoy: For civilian UAVs equipped with satellite navigation terminals, by transmitting false navigation satellite signals, the UAV navigation terminal can be deceived and confused, so that it is positioned at the false position preset by the system. No-fly zone, home point deception, route deception, etc. can be achieved through satellite positioning signal decoys.

Interference blocking class

Jammer interference: It can effectively block the communication between the drone and the console, cut off the remote control signal, data transmission and image transmission signal of the drone, so that the drone enters a self-protection state after the signal is wifi blocker, so it can achieve forced landing or driving. The purpose of the drone.

Navigation Signal Interference: Civilian drones typically use satellite navigation and positioning systems to locate themselves. By realizing navigation signal interference, the interference of drones can be blocked. After the drone loses its navigation signal, it cannot be accurately positioned, thus affecting the flight control system of the drone and limiting the flight of the drone.

Acoustic interference: UAVs have an important component – gyroscopes, which can help UAVs perceive their own flight status. The drone maintains its own balance through feedback from gyroscopes and control systems. So if you can break the gyroscope working properly, the drone won’t work properly.

Destroy the class directly

Missiles, laser weapons, microwave weapons, combat drones, conventional firepower, etc. can all conduct directional attacks on drones to achieve the purpose of directly destroying drones.

However, this method requires high precision and high cost, as well as collateral damage due to drone crashes. Therefore, it is almost impossible to directly destroy UAVs in the civilian field.

Here, as a professional manufacturer of wireless signal jammers, we first express our position: if we want to use the wireless signal jammers produced by our company for illegal activities or non-goodwill purposes, we firmly oppose and refuse to sell them. Therefore, when some customers ask us about wireless signal jammers, through questions about some actual use purposes and functional requirements, the customer’s reply is obviously slow or deliberately concealed, and we will soon be vigilant about this.

Recently, They want to buy a suitable wireless signal jammer from us. The purpose is also very clear, that is, it is used to block surveillance cameras. Usually, we will directly refuse to meet such needs. So the question is, is the wireless signal blocker we produce can’t block the surveillance camera?

Come to www.perfectjammer.com, you can get a GPS jammers kit to easily solve this problem.

Can the wireless signal blocker we produce block surveillance cameras? In fact, it is necessary to distinguish the working mode of the surveillance camera. The data transmission of surveillance cameras is divided into wired transmission and wireless transmission, and what the wireless signal jammer can achieve is to shield the surveillance cameras of the wireless transmission mode. Nothing can be done about wired transmission. Furthermore: the wireless signal jammer is a real-time shielding of wireless data. If the surveillance camera itself has its own data storage function, even if it is blocked and interrupted during wireless data transmission, after the wireless signal jammer is turned off, once the wireless data transmission resumes , the monitoring data originally stored in the local surveillance camera may still be transmitted again.

It is precisely because the purpose of some individuals using wireless mobile signal jammer is not simple, and they do not understand the technical parameters of the surveillance cameras that need to be shielded, so we will not do targeted cooperation for such needs, and it is reasonable to directly refuse.
