Russia has jammed GPS signals around NATO exercises on more than one occasion, often from a base in Syria jamming large swathes of the Middle East. Spoofing GPS signals in Moscow and the Black Sea to trick receivers into reporting they are at airports miles from their actual location is well documented.
The United States has formally expressed concern about the recent surge of Russian troops and their activities on the Ukrainian border. Two U.S. Navy ships are reportedly heading to the Black Sea to monitor the situation.
The birth of mobile phones has indeed shortened the distance between people and brought great convenience to everyone's life. However, with the popularity of mobile phones, everyone has basically reached a form that is inseparable from the body, which gives many opportunities. It can do a lot of damage. Therefore, the cell phone jammer market also came into being.
Some areas that require strict control, such as military power plants, prisons, detention centers, etc., have a very high degree of confidentiality, and mobile phones must be strictly controlled. In areas such as military power plants, prisons, and detention centers, blocking mobile phone signals can greatly reduce the possibility of leakage.
Fairness and justice are the fundamental tenets of society. There are many exams in life, from elementary school to junior high school, from the college entrance examination, from civil servants to exams, and then to other national exams. In order to prevent candidates from cheating in various large and medium-sized examinations, it is necessary to use technical means such as mobile phone signal blockers to shield the signals in the examination room to meet the needs of mobile phones that cannot communicate and surf the Internet. the Internet. For candidates, hiding is a good precaution.
Two recent reports from the Organization for Security and Cooperation in Europe describe a recent increase in gps blocker, which may come from Russian or pro-Russian forces in Ukraine. This is because Russia has increased troop numbers and activities in the border area with Ukraine.
The OSCE's obligation is to establish a Special Monitoring Mission (SMM) in Ukraine to monitor and report on unilateral compliance with the Minsk agreement. The agreement was signed by parties involved in the conflict in September 2014 to end underground hostilities.
For example, the OSCE mission uses short-range drones to monitor activity and compliance in the region. Back in November 2014, the group reported that drone operations were hindered by GPS signal interference.
GPS jamming and spoofing is an important part of Russia's arsenal to counter the technological superiority of the East over its armed forces. A 2015 article by Sputnik boasted of their electronic warfare and preventing U.S. cruise missiles from reaching their destination at the start of the 2003 invasion of Iraq. Additionally, this advanced capability "makes the carrier unusable."

What are the advantages of high-power mobile phone signal jammers?
How much cell phone jammer can block is not only related to its own signal strength, but also to the spacing between the communication base stations in the natural environment used. Another key reason is barriers. If it's metal, it's blocked right away; if it's a solid wall made of concrete, it's unlikely to penetrate. 10 times weakening; less weakening if it is sheet or glass material.
The Air Force is taking new steps to bring promising new technology to the weapons network in flight. In flight, co-targeting allows the weapon to use its advanced viewfinder to identify and pass on tactical details to other weapons so it can maneuver as needed. Recent tests of a small-diameter synergistic bomb that transmits data in flight have shown promising results and room for improvement. The Air Force tested the ability of air-dropped bombs to share purpose-sensitive data with each other in flight to customize attack specifications, locate GPS interceptors, and optimize the speed and accuracy of attack maneuvers.
The mobile phone jammer tests the high-end of the low-end frequency band of the wireless channel at a certain rate during the operation. This test rate will lead to the intrusion of the audio data signal received by the mobile phone with bit error, resulting in the mobile phone being unable to detect the slave communication. All normal microwave data signal data information released by the base station will inevitably prevent the mobile phone from establishing a connection with the communication base station, so as to achieve the purpose of intercepting the mobile phone signal.
It is easy to understand that the frequency band released by the mobile phone signal jammer invades the frequency band of the mobile phone receiving communication base station. After all, jammers and communication base stations are in competition. If the signal strength of the mobile phone signal jammer is lower than the natural environment, the output power of the wireless channel transmitted by the Chinese communication base station to the mobile phone will not be intercepted by the signal jammer. Only when the output power of the signal jammer exceeds the transmission power of the communication base station to the mobile phone Only when the output power is output, the blocking can be stopped reasonably and effectively. Therefore, when all gps blocker are used in different data signal environments, the interception interval will be different, and the direction of the communication base station and the output power of the communication base station cannot be reversed.
