DETECTING AND AVOIDING INTERMODULATION INTERFERENCE

A first device and a second device may coordinate to determine a power level or frequency in a first frequency band that is associated with causing intermodulation (IM) interference at a second frequency band (e.g., a protected frequency band). An IM interference detection test may include at least...

Zusammenfassung:A first device and a second device may coordinate to determine a power level or frequency in a first frequency band that is associated with causing intermodulation (IM) interference at a second frequency band (e.g., a protected frequency band). An IM interference detection test may include at least a first test signal transmitted from the first device to the second device via a communications medium. The second device may detect for the presence of IM interference associated with the first test signal. A series of test signals may be used to identify power levels and/or frequencies that cause IM interference in the second frequency band. A transmitting device may improve performance by increasing power for particular frequencies up to a power level that maintains IM interference below a threshold level.
