The past severl years the FCC has opened up 71-76GHz, 81-86GHz, and 91-96GHz. Products operating in this high spectrum have 5/9 availiblity at 1 mile with throughput @ 10GigE.</p> Many of the fixed wireless connectivity and availibility challenges are resolved in the millimeter wave spectrum.

Using commercially available technology, it becomes really hard to do NLOS above 6 GHz. What the higher frequencies are good for is very high bandwidth point-to-point in LOS conditions. If you can get the real estate to place them cheaply enough (a very big if) you could create a very high capicity mesh that created defacto NLOS service using a multitude of PTP links at these high frequencies (I believe GigaBeam suggested something of this nature for San Fransisco). Something to remember is that there is plenty of unlicensed/very-cheap-to-license for PTP spectrum at these higher frequencies. So, it is not so much that these frequencies don't work it is that they are relatively inflexible and widely available = not worth much money.</p> WiMax is generally for below 11 GHz and realistically for below 6 GHz fixed and 3 GHz mobile.
