Mobile phone frequency jammers, defined as devices that emit signals designed to partially or completely prevent communication between a transmitter and a receiver, are at the core of today's jamming technology. This cell phone jammer has recently emerged in the automotive and telephone markets, as these devices are used to scramble frequency without affecting other electronic devices.
This small phone scrambler device has aroused people's interest, especially since the fall of 2017, in order to prevent students from using mobile phones too much, staying up at night, etc., they have also banned mobile phones and installed cell phone jammers in some areas, such as self-study Room, classroom, etc. Some gas stations have also begun to use such equipment to protect the safety of gas stations.
