As far as I know that is all licensed spectrum, LMDS/MMDS, none of
which I own. Also had a lot of problems with LMDS spectrum years ago.
No, I like the very high directionality of this spectrum in the 60 GHz
and 80-90 GHz and I like the fact that 60 GHz is unlicensed and 80-90
is minimally licensed. That is a fee for and quick registration of
only.
Have no problem with IEEE 802.16 but I believe it is designed more for
a shared shotgun RF use and not for the rifle shot full duplex
multiple Gbps connections I am interested in.

Bob, I still don't understand what you are creating here.
The article we're referring to talked about a 10 meter range system, for
internal hookup of audio/video equipment where the video can be
uncompressed. A wireless form of HDMI, if you will. That's why the
comparison with UWB, which is intended for a similar mission, or maybe
better characterized as "wireless USB."
You seem to be adressing something else. If you are trying to use a 60
GHz carrier for a two-way last mile link, then what's wrong with the
existing IEEE 802.16, MMDS/LMDS, which is already a standard that takes
you all the way up to 66 GHz, and does so with any number of optional
encapsulations (i.e. even ATM, if you like)?
