Introduction to the principle of mobile phone signal jammer
Based on the above communication principle, the signal jammer for sale scans 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 can cause garbled interference in the message signals received by the mobile phone. The mobile phone cannot detect normal data sent from the base station, making it impossible for the mobile phone to establish a connection with the base station. The mobile phone behaves like searching the network, no signal, and no service system

Overview of the principles of cell phone jammers Introduction to the principles of mobile communications:
The working principle of a mobile phone is as follows: within a certain frequency range, the mobile phone and the base station are connected through radio waves to complete data and sound phenomena with a certain baud rate and modulation method.
