which had no access to broadband before, and which is designed to
showcase the benefits of this free spectrum."
What a bunch of politically motivated/self-serving hooey.
Are you telling me that out in a rural Virginia town, they could not
find a slice of spectrum in the 2 - 66 GHz range that IEEE 802.16 can
use? They had to use TV frequencies for this MMDS?
Typical hooey from Bert.
There are significant differences in the propagation characteristics for
the UHF band and the bands that lie above 1 GHz. This network offers far
more than a point-to-point link to one school.

It may have to do with the 'quiet zone' maintained for the giant radio
telescopes near Frost, W. Va. NO rf transmissions allowed except for one
AM radio station on 1370 KHz in the entire region.
