Prisons need powerful signal jammers

What kind of signal jammer do you need in prison? Some might say cell phone jammer, since many inmates use cell phones to secretly communicate with the outside world. Some would say drone jammers, because many prisoners use drones to transport contraband. However, it is not enough to interfere with only one signal, so we need more powerful integrated signal jammers

Designers and owner of the prison phone jammer would likely use the one in a fixed,stationary manner in order to block calls in a building,as opposed to moving in transit,motorcades.This stationary nature is more likely to be implemented in a prison using directional antennas,with multiple device of this type spread out in a prison,a configuration of prison jammers may be inter-connected and controlled by a central console.
