Mobile phones work in a certain frequency range, mobile phones and base stations are connected by radio waves, and transmit data and voice with certain baud rate and modulation mode. In response to this communication principle, the cell phone signal shield is scanned at the low end of the channel at a certain speed in the working process. The scanning speed can generate random code interference in the receiving message of mobile phone.
