Abstract

A method of intelligent dynamic frequency reuse includes transmitting a first signal on a selected frequency with a first one of a plurality of fixed stations, the signal being directed to a first one of a plurality of mobile cellular phone users, receiving a second signal for transmission to a second one of the plurality of mobile cellular phone system users at a second one of the fixed stations, transmissions from the second fixed station on the selected frequency being capable of interfering with reception of transmissions from the first fixed station by the first one of the plurality of mobile cellular phone users, determining whether transmission of the second signal on the selected frequency from the second fixed location would interfere with reception of the first first signal by the first one of the plurality of mobile cellular phone users, and transmitting the second signal from the second one of the fixed stations on the selected frequency when the transmission will not interfere with simultaneous reception of the first signal by the first one of the plurality of mobile cellular phone or receiver units. In one embodiment, the system adjusts the power level of transmissions from the fixed transmission stations to minimize interference. In another embodiment, the system utilizes information provided from the mobile receivers and/or database(s) to simultaneously transmit multiple signals to multiple mobile receivers where physical obstructions block otherwise interfering transmissions.
