Based on the above communication principle, the signal jammer 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
How to use mobile phone signal jammer
Select the area where you need to cut off the cell phone signal and place the cutter on the table or wall in this area.
． After the equipment is connected, press the power switch disconnector to work. At this time, all powered mobile phones on site are in the search network state and lose the base station signal.
Neither the calling party nor the called party can establish a call connection.
After installation is complete, turn on the power to the disconnector and turn on the power switch.
Overview of the principles of cell phone signal 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.
