Re: [WISPA] RAD/Radwin x Wi-Fi
Do you mean the traditional Alvarion VL hardware or the new cheap stuff ones ? The expensive Alvarian VL uses a standard Atheros Chipset. But Alvarion has its own MAC, which is the secret to its more robust offering. Which do you think is closer to the RadWin design: Karlnet, Mikrotik nstreme, Ubiquiti AirMax or none of the above ? None of the above.

Although costly backhaul vendors (Redline, Motorola) keep telling me that RAD/Radwin are Wi-Fi based, my testing of them insist on telling me otherwise... for instance, AirMux-200 pass with flying colors thru RFC-2544 performance testing with maximum performance (18 Mbps) even for 64 byte frames (27 kpps), which is a very good pps rate compared to the 2kpps of a Ubiquiti Nanostation (non-M). Data rates are indeed similar comparing AirMux-200 to 802.11a, although Radwin tops at 48 Mbps air rate, not 54 Mbps; the MIMO model have data rates that look very much like the MCS8-15 802.11n data rates, suggesting that there are indeed some Wi-Fi heritage in the product, no matter what the tests say.
