摘要： The invention can establish a default retransmission algorithm and an interference retransmission algorithm. The default retransmission algorithm can be a Distributed Coordination Function (DCF) based algorithm implemented in a MAC layer in conformance with an IEEE 802.11 based standard. The minimum cumulative back-off time for the default transmission algorithm can be less a minimum cumulative back-off time for the interference retransmission algorithm. The minimum cumulative back-off time for the interference retransmission algorithm can be greater than an on-cycle of the PII and less than a sum of the on and off-cycles of the PII (e.g., between ~8.3 ms and ~16.7 ms for microwave oven generated PII). A determination can be made whether periodic intermittent interference is present. If so, the default retransmission algorithm can be automatically utilized for wireless data conveyances. When PII is present, the interference retransmission algorithm can be automatically utilized.
