The use of mobile communication devices smuggled into prisons is one of the main drivers for implementing signal inhibiting solutions to block, restrict or inhibit mobile communications signals. One of these solutions is the use of mobile signal inhibitors(jammers). Signal inhibitors or blockers, commonly known as jammers, are radio devices that intentionally transmit signals to affect, block, interfere with, or saturate the communications services of mobile users. This includes calls, text messages, GPS positioning signals, data services, and Wi-Fi networks.
