Does Rfid Material Block Cell Phone Reception No Signal No Service
The principle of mobile phone (radio communication) is: within a certain frequency range, the mobile phone and the base station are connected by radio waves to complete the transmission of data and sound with a certain baud rate and modulation method. In view of the above communication principle, Does Rfid Material Block Cell Phone Reception scan from the low-end frequency of the forward channel to the high-end frequency at a certain speed during the working process. This scanning speed will cause garbled interference in the message signal received by the mobile phone, and the mobile phone cannot detect the normal data sent by the base station, so that the mobile phone cannot establish a connection with the base station. The mobile phone manifests as the phenomenon of searching the network, no signal, no service system, etc.
