onset or termination of rf interference may be reported to at least one other network entity at 440 fig5 shows a flow diagram of a method 500 determining rf interference according to another embodiment first a processor with in the sta or ap determines a rate of received fragments with fragment count system fcs errors fcserrorcount 510 at the same time the processor determines a rate of total fragments received receivedfragmentcount 520 then the processor determines the rate of change of the fcserrorcount u03b4fcserrorcount 530 at the same time the processor also determines a rate of change of the receivedfragmentcount u03b4receivedfragmentcount 540 next the processor determines the ratio of u03b4fcserrorcount to u03b4receivedfragmentcount 550 the ratio of these deltas represents the received fragment error rate then the processor determines a rate of change of the ratio of u03b4fcserrorcount to u03b4receivedfragmentcount u03b4 u03b4fcserrorcount u03b4receivedfragmentcount 560 finally the processor determines the rf interference levels based on the u03b4 u03b4fcserrorcount u03b4receivedfragmentcount 570 a sudden increase in the received u03b4 u03b4fcserrorcount u03b4receivedfragmentcount indicates the onset of a new rf interference at that sta or ap if the difference in u03b4 u03b4fcserrorcount u03b4receivedfragmentcount is greater increasing received fragment error rate than a selected threshold value in db for a selected time window then rf interference onset is detected at that sta or ap if the difference in the u03b4 u03b4fcserrorcount u03b4receivedfragmentcount is less decreasing.
