1. A method, comprising:
- analyzing, by a system comprising a processor, within a wide frequency band, power levels of received signals in specified frequency bands;
determining, by the system, an average composite wideband power level that excludes a portion of the power levels of the received signals;
detecting, by the system, interference according to an adaptive threshold based on the average composite wideband power level; and
generating, by the system, an interference report based on the detecting of the interference.
