Brad,
Could you tell us more about what infrastructure is required to support
the 2400 subscriber system you are referring to? How many tower
locations, sectors per tower, backhaul used, etc.? This is interesting
stuff
Trees are sponges -- there is no scatter with them
That said, you're are causing yourself undue headache trying to do NLoS with
2.4 -- especially when 900 MHz is readily available

Paul,
5 GHz works NLOS in an urban environment. Bouncing around buildings, etc.
Look at the success of Redline and Orthogon. OFDM and 5 GHz works well for
them. An environment with trees is different. Trees absorb the signals,
instead of bouncing them. Especially wet trees!
We utilize 2.4
for
tree NLOS environments than 5GHz?

I thought that was it but needed someone to clarify ;) What about 5GHz
, because

Not all OFDM radios are created equally (especially PTMP). In many areas of
NorthEast USA we have 1 mile radius's with eave mounted BreezeAccess VL
Subscribers (5.8 Ghz) doing mod 6 which reflects a 10 meg true data rate.
Typically these are obstructed NLOS links
with this model. I have 2,400 subscribers
(and growing) deployed in this fashion with one customer. Brad
