In order to manage cellular phone communications within a secure facility, one must control whom is allowed
to make and receive cell phone calls and who is not within the walls of the facility.
To do this, it must be taken
into account that cell phones smuggled in or overtly carried in all need to be discovered and dealt with. If a
call is not authorized, then controlled termination of the call must be executed.
How can cellular phone traffic inside of a secure facility or prison be controlled? By actively detecting and
jamming radio signals manually or automatically within controlled environments.
