The mobile phone and the communication base station are connected by electromagnetic waves, and the data information and sound transmission are completed with a certain serial port baud rate and deployment method. For the basic principle of this type of communication, the mobile phone signal jammer will go to the high-end scanner at a certain rate at a certain rate during the whole working process. This scanning rate can cause error code interference when the mobile phone receives the message format signal, and the mobile phone cannot detect all normal data information published from the communication base station, so that the mobile phone cannot form a connection with the communication base station.
