Principle of Signal Jammer Module

Within a certain frequency range, mobile phones and base stations are connected through wireless radio waves to complete data and sound transmission with a certain baud rate and modulation method. Signal Jammer Module scan from a low -end frequency from a certain speed to the high -end at a certain speed at a certain speed. The scanning speed can form garbled -size interference in the mobile phone receiving message signal. The mobile phone cannot detect the normal data issued from the base station, so that the mobile phone cannot be connected with the base station to achieve the purpose of blocking the mobile phone signal. No service system and other phenomena.

In layman's terms: Signal Jammer Module will emit frequency when working, interfere with the downlink signals of its base station. If the power of the shield is greater than the power of the local base station signal, the phone will have no signal. If the shielder's power is less than the local base station, The power phone of the signal will have a signal.
