disruptor communication

The working principle of mobile communication is that within a certain frequency range, the mobile phone and the base station communicate through radio waves, and complete the transmission of data and sound with a certain baud rate and modulation method. When the mobile phone communicates, it communicates with the base station through the uplink frequency, and then transfers the signal to the MSC mobile service switching center to realize the call. In the standby state, the mobile phone communicates with the base station through the BCH broadcast control channel. Once there is a call demand, first ask the MSC through the BCH. The MSC allocates the frequency blocker channel according to the channel status in the cell, so that the mobile phone can jump from the BCH to the service. Realize the conversation on the channel. The mobile phone signal jammer scans from the low-end frequency of the forward channel to the high-end at a certain speed during the working process according to the above-mentioned principle. This scanning speed can cause garbled interference in the message signal received by the mobile phone, and the mobile phone cannot detect the normal data sent from the base station, so that the mobile phone cannot establish a connection with the base station.
