All,
focusing on the future of white space is so far off that you can't even
assume that the current technologies used will even apply ( or there
will be a market
for WISPs to service ) If I was any of you I would be banging down the
FCC's door to get decent output power ( greater than 1w EIRP )
for 3.65 otherwise there is no NLOS magic wisp bullet ever.
its back to good ol LOS!

To reinforce Steve's comment, Butch it is not only the technology that
will very distinct, but the applications running across such spectrum
will be distinct. Most likely we'd see some sort of future TV-ish
application, one that is interactive, user selectable in terms of
content and God knows what else.
And as Steve noted, the technology will be a big challenge. Not only
must such devices deal with protecting broadcasts, but it will also
have
to not interfere with the millions of low end receivers in the market
sitting in every home in the U.S....TVs.
Basically, for the white space a whole ecosystem will have to be
created
and evolve and know one has any real idea what this will look like.
I would estimate that we are years from any mass usage of white space
and frankly, bwa vendors have their hands full at the moment with the
other current and forthcoming bands. For example, our R&D run rate is
better than $13M a quarter -- a massive pace, especially relative to
those companies you are familiar with (it is a number equivalent to
some
WISP vendors full year of revenues) and every dollar of that is going
toward development and evolution of products for the current and
growing
unlicensed and licensed markets.
Long before anything can be done with the white space we have to deal
with 3.65 and 700, much less all the current frequencies.
BTW, I do know a little about the device the IT companies forwarded to
the FCC. Let's just say that these IT companies are gurus of tech, but
they are clearly not exactly radio guys!

Well, most that can are probably doing what we are doing Mike,
which is to study, monitor, and plant some seeds. It is a bit early
to market an actual system. The nature of the band will require
some atypical technologies and the applications will likely be
broader than fixed wireless as we know it today.
I presume you're referring to mobile applications. I know that you
(Alvarion) have a mobile 900 product, so the step to this lower band
should be and easy one for that technology anyway.
You don't have any information on what device the FCC tested and
failed, do you? You're the guy that would know if anyone does. :-)
