Jamming Signal blocker Purpose

The basic principle of a jamming device is to emit the same radio frequency signal as a cell phone. Since the frequencies are the same, the cell phone cannot tell which signal is a regular base station signal, thus "jamming". As long as there is a machine on the same frequency as the phone, the base station will make a lot of "noise" when it tries to connect to the phone. You will find that the signal from the phone is unrecognizable, so you will refuse to communicate with the phone.

Calls can be intercepted so suspects cannot be contacted outside the area. The jamming signal can be used in areas where radio transmissions are hazardous (areas with potentially explosive atmospheres), such as chemical storage facilities or grain elevators.
