cell phone jammer

The working principle of a mobile phone signal jammer is that, in general, the frequency emitted by the cell phone jammer interferes with the normal frequency of the mobile phone receiving the base station, making the mobile phone unable to connect to the base station, making it impossible to make calls, send and receive text messages, and surf the Internet. As long as in the room where the shield is turned on, all China Mobile, China Unicom and Telecom mobile phones cannot be used normally. If you want a mobile phone to work normally, unless the mobile phone signal is very strong, that is to say, there is a signal amplifier nearby or in a building. For example, if a mobile signal amplifier is installed in the building, it is difficult to shield the mobile phone. If it is China Unicom's signal amplifier, then Unicom mobile phone is difficult to shield. Therefore, the only way to use a mobile phone is to install a mobile phone signal amplifier in the place of use.

Signal jammers are increasingly being used in school examination rooms, dormitories, prisons, detention centers, courts, confidential meeting rooms and other places. As long as the signal jammers are within the range of the signal jammers, mobile phones cannot normally make calls, send and receive text messages, and Online. In this case, there is no way to crack it, only a mobile phone signal amplifier can be installed to counter it. Because the mobile phone signal jammer interferes with the mobile phone to receive the normal frequency sent by the signal amplifier through its own frequency, so as long as there is a signal amplifier, the signal of the mobile phone will become stronger and the jammer will be more difficult to shield.
