Abstract
Methods and systems for determining transmission channels for short range transmissions are disclosed. A transmitter provides short range transmission to a broadcast receiver configured to receive and tune channels within a signal spectrum. Channels within the broadcast signal spectrum are scanned, and an indication of received signal strength is obtained for each channel. The received signal strength indication (RSSI) can then be compared to a threshold power level that correlates to a signal level that the transmitter will be capable of overpowering based upon the transmission power of the transmitter. The scan results in an indication of one or more channels that have received signal strengths below the threshold power level of the transmitter.
