When the mobile phone is working, it is within a certain operating frequency range. The mobile phone and the communication base station are connected using electromagnetic waves, and information and sound effects are transmitted with a certain serial port baud rate and deployment method. For this type of communication principle, the signal jammer passes from the low-end rate of the wireless channel to the high-end scanner at a certain rate during the operation process. This scanner speed can…
