Nowadays, cheating in the college entrance examination happens every time, and students who do not study hard will always think of these wrong ideas. Mobile phones do bring convenience to people's lives, but they are not allowed to be used in school examinations. With the advent of mobile phones, students began to learn to cheat with mobile phones, but they could not completely eliminate the problem of using mobile phones in the examination room. At this time, cell phone jammers play a very important role. So, apart from using cell phone jammers in the school examination room, do you know where they are used?

The application scope of cell phone jammer is very wide. In addition to the use of cell phone jammer to timely interfere with the mobile phone signals transmitted around the examination room during the school examination. It can also be used during important meetings. The cell phone jammer can well interfere with the mobile phone signal and prevent important information in the meeting from being leaked. In many military bases, large cell phone jammers are also used to prevent important military information from being leaked, and criminals can be better prevented by intercepting communication signals.

When the cell phone jammer works in the above places, it can transmit signals in the same frequency band as the base station, thus interfering with the reception of the mobile phone signal. Therefore, the mobile phone cannot detect the signals sent by the base station. This interference makes the connection between the mobile phone and the base station impossible. In this case, the communication equipment cannot send messages and make calls.
