Nowadays, mobile phones are indispensable in people's lives. Everyone holds a cell phone from morning to night, but some areas will block their signal. Then I will tell you the purpose and usage of the cell phone jammer
What is the use of mobile phone jammer?
Telephone signal interceptors are mainly aimed at various examination rooms, schools, gas stations, churches, courts, libraries, conference centers, theaters, hospitals, governments, finance, prisons, military places and other places where the use of mobile phones is prohibited. According to understanding, the mobile phone signal blocker on the market can limit the mobile phone signal to an area 500 meters away from the launching station. The shielding radius is adjustable, covering an area of more than 30 square meters. The mobile phone signal shielding device can only shield mobile phone signals and does not interfere with other electronic equipment. During operation, the shield scans from the low end of the forward channel to the high end at a certain speed. The scanning speed will cause error code interference in the message signal received by the mobile phone, and the mobile phone cannot detect the normal data sent by the base station, causing the mobile phone to fail to establish a connection with the base station. The mobile phone has such phenomena as network search, no signal, no service system, etc.
