Cell phone jammer can disrupting the communication between the phone and the cell-phone base station, effectively disabling mobile phones within the range of the jammer, preventing them from receiving signals.

Such devices use signal elimination to block signals by transmitting signals at the same frequency as the interference signals. Similar equipment is manufactured to block signals in environments where cell phone activity may not be desirable, such as theaters, churches and operating rooms.
