  • System for mobile communications in coexistence with communication systems having priority
    Patent number: 6449461
    Abstract: A mobile communications system for permitting the communications of a mobile unit in proximity to a communications service having priority over the communications of the mobile unit. An interference zone is formed around the priority communications site such that if the mobile unit were to transmit in the frequency band of the priority system, interference would be created with the operation of the priority receiver. In order to eliminate interference with the priority system by the mobile unit, a proximity detector determines if the mobile unit is located in the interference zone. Once the determination has been made that the mobile unit is located in the interference zone, the mobile unit alters its transmission to eliminate the interference of the mobile unit with the priority service.
