Abstract:
1. A cellular telephone detection system for detecting unauthorized cellular telephone usage within predetermined zones within a facility, comprising: a plurality of cellular telephone transmission detectors, each detector operatively associated with a predetermined zone within a facility and configured to produce a detection signal upon detection of cellular telephone transmissions within its respective predetermined zone, one or more of said cellular telephone transmission detectors are positioned within the facility such that their respective detection zones at least partially overlap a respective detection zone of at least one other of said plurality of cellular telephone transmission detectors, and at least one of said cellular telephone transmission detectors is capable of detecting non-cellular two-way communications; an interface device coupled to each of said plurality of cellular telephone transmission detectors; a telephone system coupled to said interface device, wherein said telephone system is configured to receive one or more detection signals from one or more of said plurality of cellular telephone transmission detectors and to generate one or more notification messages indicative of detected cellular telephone transmissions; and a jamming device configured to jam the use of at least the unauthorized cellular telephone based or a control signal from the telephone system, wherein the telephone system is configured to control the jamming device to jam the use of at least the unauthorized cellular telephone based on the satisfaction of a condition, and upon receipt of the one or more detection signals, and wherein said one or more notification messages further include an indication of a detected signal level for each cellular telephone detected in a respective detection zone.
