1. A method, comprising:

  • receiving, by a system comprising a processor, information from a device that detects a narrow band interferer according to an adaptive threshold to obtain received information, wherein the narrow band interferer is detected by the device in a wide frequency band, wherein the adaptive threshold is determined by sampling at least some narrow band signal power levels in the wide frequency band, and wherein the information is descriptive of the narrow band interferer;

    determining, by the system from the received information, that a source for the narrow band interferer comprises a communication device transmitting wireless signals;

    determining, by the system, a mitigation strategy according to the received information; and

    causing a base station of a plurality of base stations of the system to reduce interference caused by the narrow band interferer according to the mitigation strategy, wherein the mitigation strategy comprises causing the communication device to adjust operations of a wireless transmitter of the communication device by switching to a new operation frequency for the communication device.
