description A method and system for controlling the use of mobile cellular communications within defined regulated areas are disclosed. The system transmits RF interfering signals on the frequency band typically used by cellular base stations to prevent effective communications between mobile units located within a given regulated area and cellular base stations. In the preferred embodiment, the system waits until mobile unit transmission from within the regulated area is detected and thereupon transmits a blocking signal which prevents effective handshake from taking place.
