This is apparently an incorrect assumption. It was a Mikrotik engineer that made the statement that NStreme is based on 802.11, but for NStreme Dual, they have apparently made changes to the way it works so that all transmissions happen on one radio only. I would go with their word on that. -- Butch Evans Network Engineering and Security Consulting 573-276-2879 http://www.butchevans.com/ My calendar: http://tinyurl.com/y24ad6 Training Partners: http://tinyurl.com/smfkf Mikrotik Certified Consultant http://www.mikrotik.com/consultants.html WISPA Wants You!

Re: [WISPA] FDX Wireless
Tom, just catching up on these. Is what your saying below, that Mikrotik's Nstreme2(dual card, FDX, PTP) still has a small amount of transmit occurring on the designated Rx card? I've always assumed that it was truly full duplex. But I've never really tested, wondering how sure you were on your PS below? Thanks Jon Langeler Michwave Tech. there is still some communication going on on the Tom DeReggi wrote: Star OS now has a FDX option. So does Tranzeo. (meaning a seperate radio card for each direction) PS: I'd argue that no 802.11 radio is 100% true Full Duplex, meaning the 802.11 proto responds on the same channel, but at Layer 3 they seperate which channel is for sending and receiving. For True FDX, most of the Licensed Part101 Gear does it. TrangoGiga, Cable Free, Dragonwave, Ceragon.
