The GPS signal interference technology is loved by people everywhere. The working frequency and signal strength of the GPS signal blocker are greater than the expected signal on the receiver. Therefore, if the jammer has sufficient power and a wide enough signal spectrum, it may interfere with all receivers and trick the receiver into receiving the interference signal instead of the expected signal.
An Army official in the United States also expressed the hope that the signal jammers currently installed on drones will play an important role in electronic warfare and will invest more money in research on jamming technologies. On the Syrian battlefield, four U.S. officials said that Syrian forces have been interfering with some U.S. military drones flying in Syrian air, severely affecting US military operations. Demonstrating that such drone jammers are extremely destructive, Syrians have begun using some high-end drone jamming technology to block some small US aircraft.
Interference technology is also very popular in the civilian field. Parents use signal jammers to prevent children from playing mobile phones. Schools purchase WiFi jammers to prevent cheating in exams and ensure fairness and justice in exams.Companies can use WiFi jammers to improve employee productivity and prevent employees from being lazy with mobile phones during work hours.
