Any solution for NLOS on my Mikrotik Outdoor AP???
I have many trees and obstructions…
Well you have sevaral options:
Run 2.4ghz at 1/4 spectrum (5mhz) = 3dbm increase … punches through trees pretty well. ?!
Use 900Mhz gear, specifically the sr9 card made by ubiquiti networks. … best solution and works real well. The only drawback is the noise exhibited in the 900Mhz band… for that you will have to use either hori. pol antennas or noise cavity filters.

Others can relate …
Elevation and proximity to the noise makes a huge difference on 900MHz. About 60ft, at tree top level, I have no issues with noise, excellent range and signal. At 130ft within a half mile of a celular tower, I have problems in G mode (20/10 and 5MHz) and signal drops occasionally in B mode, but rarely disconnects.
As my expirience show, 5/10 Mhz is worse with same power in NLOS conditions.
For example Atheros XR seems using Turbo (40 Mhz).
which one {(2.4ghz @ 1/4 spectrum 5mhz) or (sr9) } gives more bandwidth in NLOS links and in 50% NLOS links?

I can’t see the 2.4GHz being better at NLOS than 900MHz. Nothing I’ve done with 2.4 even comes close to 900MHz.
My way of looking at it comes to return on investment. If you can get 2.4GHz to connect reliably, it is much cheaper than 900MHz. Don’t get too attached to any one frequency, they all have their strengths and weaknesses.
If you can get 2.4GHz to connect reliably, it is much cheaper than 900MHz.
we always use only sr2/xr2 @2.4GHz, sr9 is not quite expensive than sr2/xr2…
we used sr9 before in absolutely NLOS successfully, but i’m afraid there is no possible to pass much bandwidth on 900MHz.
i am interested to try sr3, but there is imposible to buy it in our country…
i wonder is sr3 work fine on NLOS… or even 50% NLOS
If you really want to establish high bandwidth connection there should be Line Of Sight even in 900MHZ or 2.4GHZ. NLOS works good when you have enough reflections and used 900MHZ frequencies.
