I was elated to see that Cambium will be developing a 60Ghz radio in the coming year. Here is my suggestions moving forward.
AP - 60Ghz only radio with a sectorized antenna / beamforming allowing upto 30+ connected clients @ 100+Mbps ea or better. SFP+ a must
SM - 60 GHZ with integraded 450 SM radio with seamless failover. SFP+ option ...Primary radio 60Ghz, but once below a certian threshold seamlessly switch to 5GHZ until channel conditions or weather conditions are good. Could accomplish the same with a seperate SM...but I'm just asking. ;.>
This setup will allow us to put a 450i or cnMEDUSA on the same tower then / if 60 GHZ fails to serve the customer still hs internet. Especially useful in business type senario.
