This is not your typical OFDM radio set - the back end is a licensed type radio setup to run in 24ghz.
I'm not that worried about rain fade around here. Western Nebraska used to be considered part of the "Great American Desert" - so heavy rain or snow is not a regular occurrence. I've got two other wireless links that get back to that location from other places, so if it does drop out, I can cover it. FWIW, the 85meg testing was not the rigorous testing that many do - I just did a simple tcp test between the RB1000 routers on both sides to see what speeds I would get. My guess is that the RB1000s are the limitation, not the radio.
