My understanding was they were using standard Wifi Chipsets, but provided their own TDD mac. Similar to the concept of Alvarion VL, that uses Atheros chipset, with their own proprietary MAC. I'm pretty sure RadWin was the first to do this to accomplish immulated Full Duplex, with a single half-duplex designed chipset. This was way before, all the recent trend SoftwareTDD packages. The units are also the same as the equivellent Ceragon models. So there is some intellectual property that was licensed or oem'ed to the other, to make that viable. Outside of that, I cant help.
But thought I'd ask..... What testing tools are you using to perform RFC-2544 performance testing ?
