Has anyone looked into implementing the higher bit rates (5.5Mbit and 11Mbit) of 802.11b using complementary code keying (CCK)? If CCK does have to be implemented from scratch, would it be more beneficial to implement G, which would provides a large number of speeds with one scheme (OFDM)?
Also, does anyone know if the BBN code on the USRP could communicate with hardware 80211b (ASIC) equipment? I've heard that there are issues with ack latency. If there is a problem, did the BBN people bother to implement the acks in their code?
