ADAPTIVE INTERFERENCE AVOIDANCE METHOD

摘要

The method for operating a two-way communications service station having a maximum transmitter power adapted to avoid interference to broadcast station receivers is disclosed. The communications service station shares a frequency band with the broadcast service station transmitter. The method includes periodically tuning the communications service station to the frequency band being used by the broadcast service station and detecting the presence of signals above a predetermined power level on frequencies known to be used by the broadcast station. The method further includes raising the maximum transmitter power limit for the two-way communications service station to a higher power level if the power level of the detected signal is above the predetermined power level.
