A method ( 10, 40 or 70 ) or system ( 200 ) of detecting periodic intermittent interference (PII) can include indirect detection by tracking ( 14 ) retransmission statistics of isochronous traffic or alternatively tracking channel probe request failures corresponding to temporal characteristics of microwave oven interference. Such tracking can be done in a number of ways including tracking ( 16 ) retransmission statistics by tracking MAC layer statistics or by tracking retransmission statistics for Voice over WLAN or by tracking a number of retransmission attempts required per transmission opportunity. In another alternative, the method can track ( 18 ) success and failures of probe requests for data traffic. The tracking schemes can use correlation. The method can further introduce ( 28 ) hysteresis in the detection of the PII to prevent rapid entering and exiting from a current detection mode. The method can further operate ( 29 ) in a direct PII detection mode if the indirect detection mode indicates PII. |
