PtMP 3.5 or 3.65 services should never be implemented with non line of sight, or through trees. In a typical TDD airtime system, no matter what it is, one client out of twenty on an AP radio with poor signal (let's say, -77 on both chains) will consume more air time and drag down the performance of the entire AP. There's a reason why all the deployment guides for modern WISP PTMP radios are quite insistent on true clear fresnel zone between CPE radio and AP. But if I had a dollar for every shoddy 802.16d-2004 or 802.16e based WISP trying to shoot through thick foliage or even install CPEs inside peoples' windows....
