Now our wireless signal mobile phone jammers are mainly used for TV station broadcasting and other purposes. Since the invisible earphone receiver is only the size of a soybean and can be placed in the ear canal, it will be difficult to detect this product if it is used to cheat on an exam. Cheating specifically detects the electromagnetic waves emitted by the invisible earphone transmitter, and can accurately locate it, so that the wireless invisible earphone is no longer invisible, and fundamentally eliminates the illegal use of wireless invisible earphones in the examination room. Then the emergence of Cell Phone Jammer Components perfectly solves the cheating phenomenon. cell phone jammer
The test signal jammer first uses a specific speed to scan from the low end of the forward channel to the high end, and this specific scanning speed can cause a garbled interference in the message signal. At this time, the mobile phone can be used. The data sent by the base station cannot be detected, so that the mobile phone cannot contact the base station. At this time, the mobile phone displays the status of no network and no service. Therefore, according to this principle, it can be seen that the exam Cell Phone Jammer Components can effectively guarantee the shielding. Lost the 4G signal of the mobile phone. Because of this very obvious effect, it has now been vigorously promoted in the examination rooms of various universities, and it can be seen in many examination rooms.
