[Discuss-gnuradio] Cognitive Radio on agenda for FCC's meeting in March

This msg is about "Cognitive" radios, not just software-defined
radios.  Cognitive radios make major adjustments in their transmission
and reception behavior, based on observing the local radio environment.

Cornell makes some good points.  There are small areas of the spectrum
where NOBODY can transmit, so that passive receivers such as
radiotelescopes can receive.

I've been advocating for defining a simple scheme for "posting"
frequency bands with machine-readable signs (like the "No Hunting"
signs found on trees and fences).  It would have to be simple enough
that every cognitive radio transmitter could implement it, listening
to learn the rules of the neighborhood before transmitting.  The radio
astronomers could "fence off" their frequencies and physical locations
by occasionally transmitting these "No Trespassing" signs on a nearby
coordinating frequency.  Anyone interested?

This is presumably going to be a rule in ET Docket 03-108.

There's some continuing ex parte activity there.

Here's a reply comment critical of us and PK from the radio
astronomers at Cornell.
