When people buy a jammer, they want to learn more about what a cell phone jammer does and how it prevents a cell phone from receiving a signal. This will give you a detailed introduction to the principle of mobile phone signal blocking.

When the mobile phone signal jammer is working, it sends out interference signals to interfere with the channel frequency band of the base station. The interference signal increases the bit error rate of the channel, reduces the signal-to-noise ratio of the channel, and makes the mobile phone unable to decode the information sent by the base station normally. It makes the mobile phone unable to establish a normal connection with the base station. When the mobile phone cannot determine its service area after several attempts, the mobile phone will display no signal, search for the network, and be out of the service area.

To put it simply, the function of the mobile phone jammer is to send out interference signals, which seriously damage the local magnetic field, so that the signal cannot be transmitted normally, and the mobile phone cannot normally receive the signal from the base station.

The above is the introduction of the function of the mobile phone jammer. Let's introduce a mobile phone signal jammer product of Lingxin Technology.
