Abstract

Corrupted frames with CRC errors potentially provide a useful channel through which information can be transmitted. Using measurements taken in an outdoor environment, it is demonstrated that for 802.11 wireless links the channel provided by corrupted frames alone (i.e. ignoring frames with PHY errors and frames received correctly) can be accurately modelled as a binary symmetric channel (BSC) provided appropriate pre- and post- processing is carried out. Also, the channel provided by corrupted frames and other frames combined can be accurately modelled as a hybrid binary symmetric/packet erasure channel. Importantly, it is found that this hybrid channel offers capacity increases of more than 100% compared to a conventional packet erasure channel over a wide range of RSSIs. This indicates that the potential exists for significant network throughput gains if the information contained in 802.11 corrupted packets is exploited.
