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.

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.

　　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."
