The Spectrum Bubble?

  1. wimax is on a different frequencies and not for these higher bands. the whole thing is that these 21-39 GHz frequencies don’t work…. people are just confusing the two because its all fixed wireless and all that crap.

  2. WiMax is generally for below 11 GHz and realistically for below 6 GHz fixed and 3 GHz mobile. 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.

  3. Many of the fixed wireless connectivity and availibility challenges are resolved in the millimeter wave spectrum. 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.
