Patent ID: 8248995

Claim:
A communications system comprising: at least one first frequency agile radio, including: at least one position device configured to determine a position of the at least one first frequency agile radio and generate a corresponding at least one first position signal; and at least one frequency agile receiver configured to measure a power of a transmission at the at least one frequency and generate a corresponding at least one power signal; and at least one second frequency agile radio, including: at least one second position device configured to determine a position of the at least one second frequency agile radio and generate a corresponding at least one second position signal; at least one frequency agile transmitter configured to transmit at least one transmission signal at the at least one frequency; at least one controller in communication with the at least one second position device, the at least one frequency agile transmitter and the at least one first frequency agile radio and configured to: determine a plurality of position coordinates of the at least one first frequency agile radio, based on the at least one first position signal; determine a plurality of signal power datums, based on the at least one power signal; estimate a coverage area of the at least one primary transmitter, based on the determined plurality of position coordinates and the determined plurality of signal power datums; determine an interference-free transmission characteristic, based on the estimated coverage area of the at least one primary transmitter and the at least one second position signal, the interference-free transmission characteristic including a maximum interference-free transmit power value; and control the at least one frequency agile transmitter to transmit the at least one transmission signal to at least one of the at least one first frequency agile radio in accordance with the interference-free transmission characteristic.
