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.
