An interesting read. It may be worth contacting Paul to ask if he has looked at 802.11, although I would expect the answer to be no. Since my previous email I have remembered that Robert Havelt presented some SDR 802.11 FHSS work in 2009, the slides are available here: https://www.blackhat.com/presentations/bh-europe-09/Havelt/Black-Hat-Europe-2009-Havelt-FHSS-Network-Security-slides.pdf I can't seem to find a video of the presentation.
