I'm generating this thread simply for informational purposes, and what we have found in our experimentation with the 450M/b platform over the past 8 months.
About us: We are a WISP out of the Central Oregon area, NW United States. Our region is rural, and vast... lots of hills/buttes/mountains, etc... RF Environment is DECENT to say the least. Since the area is vast and rural, WISP's flourish here, and we are accompanied by at-least 2-5 other companies on most towers we have presence at. Spectrum is coordinated amongst ourselves usually, but can get dicey at times!
Attached to this are 2 screen shots. One is an AP of ours hosting only 24 units as of current, at 5670 Mhz, 30 Mhz wide. Take note of the Uplink SNR's and overall signal strengths here.
The second screenshot is of the same AP, same VC's, only difference is the AP transmit frequency. This time, we moved to the 5.1 band, obviously maximizing our EIRP limits. Again, take note of the new Uplink SNR's and Signal strengths.
We have fought with some 450b units, having issues registering... dropping randomly... all sorts of production network issues. But I imagine these will be no more given the recent change. This is probably no new news to anybody, given a low EIRP band... (We suspected the same, but took some time to coordinate frequencies.)
Mostly, we were amazed by moving to the hotter band, how MUCH better all of the Uplink statistics became. I expected maybe another 5-7 dB gained by each VC, but in this case as you can see... Most increased by approximately 20-25 dB! Also with this came added throughput, most VC's were receiving 65-70 Mbps downlink at maximum. (We are running our ration 75/25) Now most VC's are receiving 120-150 Mbps downlink, aggregates of 165-180 Mbps.
I loved these 450M/b units at first sight/turn up of first VC... But this made us re-fall in love with the product all over again, and realized our money spent is certainly not in vein. Again, this is more of a informatitive post and success story from our unit and area.
Thanks for listening to me ramble, and hope this helps some folks in some shape or form.
