For the uplink and downlink channels of the mobile phone system, it uses techniques such as frequency multiplication, frequency division, and frequency hopping filtering to analyze the required shielding frequency; customize a spherical shielding space according to the power of the shielding device, and automatically form a shielding magnetic field within a specified range. Make mobile phones (including PHS-PHS GSM-China Unicom, China Mobile, CDMA-China Telecom) invalid in this space. When the jammer is in working condition, it can disable the signal receiving and sending function of the mobile phone within the specified range, and cannot dial out and dial in, so as to achieve the purpose of mandatory prohibition. It can be applied to various places such as examination rooms, conference rooms, gas stations, oil depots, churches, hospitals, courts, military powerhouses, libraries, theaters, etc. However, in densely populated areas such as schools, it is prohibited to set up radio stations with excessive electromagnetic radiation, and mobile phone signal jammers are not allowed to be used without authorization.

3. After the equipment is connected, press the power switch and the disconnector to work. At this time, all the mobile phones turned on at the scene are searching for the network, and the base station signal is lost. Both the caller and the caller cannot establish a call.
Brief introduction to the principle of mobile phone signal jammer (mobile phone signal interceptor)
In view of the above communication principle, the mobile phone jammer scans from the low end frequency of the forward channel to the high end at a certain speed during operation. This scanning speed can cause garbled interference in the message signal received by the mobile phone, and the mobile phone cannot detect the normal data sent from the base station, so that the mobile phone cannot establish a connection with the base station. The mobile phone is manifested as the phenomenon of searching the network, mobile phone no signal, no service system, etc.
