Hi, I don't have any recommendations for hardware sources I'm afraid. I mostly use a local distributor and ebay :) Yin reported having the basic TDMA stuff working between two stations but he ran out of time before he could fully verify everything is working as per Sam's TDMA paper from a few years ago. So, if you're willing to help debug the two-station TDMA mode (which I'd like re-verified and debugged, far before we try enabling 11n in TDMA mode, or even >2 stations in TDMA mode) then I'd suggest grabbing any supported 11n NIC. The SR-71 NIC and SR71-5 NICs will work. (The AR9220 NICs in 2ghz mode, like the SR71-2 NICs, do work but not when AH_DEBUG is enabled.) There are other vendors, such as unex and compex, they sell atheros 71xx series hardware with AR9220/AR9160 series NICs. You can also grab the AR724x series minipcie hardware with AR9280 series NICs too. But please, keep in mind that TDMA likely requires a bit of attention to get it into shape. :) Adrian
