I agree we live on different planets. Mine -- I'm now making sales
presentations to broadcasters -- has not an iota of hype. But then, I'm an
engineer trying to sell his wares, not a marketing drone only interested in
the payday. And, I'm ONLY talking to other engineers.
"60 thru 80 GHz, 2.4 GHz, 3.5 GHz, 5.2 GHz, 5.8 Ghz, lower 700 MHz, it
looks like some of the TV spectrum below channel 51 and even short range
lasers."
Cool. You have defined a kludge. I tend to doubt that you will use "lower
700 mhz" in any sense but an STA, but on the planet of hype, every hypester
is a king.
I guess you've given up on COFDM: I'm sure the complete lack of interest
among content owners and distributors is a serious bar to your "broadcast"
dreams.
As for the rest of your response, I won't give it even the dignity of
reading it.
You do live on the same planet at cable hypesters. Are you visiting the
Rigas trial in your town and crying in the gallery for what could have been
if only the pawns had kept lying?

No I watched a panel of at least seven cable CEO's discussing cable, its

You didn't mention 802.11b but some narrowly define Wi-Fi as 802.11b and
2.4 GHz. A wider definition would include 802.11g and 802.11a at 5.8 GHz.
http://www.wi-fi.org/OpenSection/glossary.asp?TID=2
"An interoperability certification for wireless local area network (LAN)
products based on the Institute of Electrical and Electronics Engineers
(IEEE) 802.11 standard."
"Wi-Fi , 802.11, is composed of several standards operating in different
radio frequencies: 802.11b is a standard for wireless LANs operating in
the 2.4 GHz spectrum with a bandwidth of 11 Mbps; 802.11a is a different
standard for wireless LANs, and pertains to systems operating in the 5
GHz frequency range with a bandwidth of 54 Mbps. Another standard,
802.11g, is for WLANS operating in the 2.4 GHz frequency but with a
bandwidth of 54 Mbps."

"Broadcasting" as in OTA broadcasting is being supplanted by cable and
satellite. There is no need other than regulatory for a broadcaster to
deliver his signal via OTA. It is and could all be delivered via other
microwave or fiber connections. The rational for using this spectrum for
such broadcasting is dwindling and as it approaches zero the legal
requirement that a broadcaster must be able to deliver via his spectrum
a clean signal to the cable headend in order to qualify for must carry
does not justify the use of the spectrum anymore.

700 MHz is not per se a Wi-Fi frequency but owners of channels 54, 55
and 59 which were recently auctioned are contemplating the use of this
700 MHz spectrum for Wi-Fi type services. If it is semantics we are
interested in then the use of licensed spectrum would not qualify by
definition as Wi-Fi.

It will be proved in the doing. A lot of video is being watched OTI
(Over the Internet) today. The technology to increase bandwidth to the
next level is available. IP is not regulated and a plethora of media
devices to help receive, store and distribute video is being invented
and even sold already.

You will have to check the FCC site for Auctions #44 and #49.

As I read it the FCC is thinking of allowing the "unlicensed" use of
this TV spectrum. It can be used by individuals or entities like a WISP.
No license means no license however. This is from the FCC release of
*May 13, 2004*
"The Commission’s Part 15 rules have enabled the development of a large
number and variety of devices including wireless computer networking
cards, wireless connections to printers and keyboards, and wireless
headsets and computer connections for cellular and PCS phones. Many of
these devices currently operate in the 2.4 GHz and 5 GHz bands.
In the Notice, the Commission proposed to classify the unlicensed
broadband devices that could be used in the TV bands into two general
functional categories. The first category would consist of lower power
“personal/portable” unlicensed devices, such as Wi-Fi like cards in
laptop computers or wireless in-home local area networks. The second
category would consist of higher power “fixed/access” unlicensed devices
that are generally operated from a fixed location and may be used to
provide a commercial service such as wireless broadband internet
access. The Commission proposed to allow both of these types of
operations in the TV spectrum, provided appropriate measures are taken
to ensure that operations are limited to unused TV channels"

We disagree with what underutilized means. Your millions out of 285
million citizens and your single program channel when multiple HD or 12
SD programs could be broadcast is my definition of underutilized.
The FCC proposes to use unused channels at low power levels.
The broadcasters can watch "our" spectrum all they want. It is how well
they are using it and how many viewers still use it that matters.

My position is and was that I fervently hope that broadcasters are stuck
with 8-VSB for the foreseeable future. Works for me. There is no mobile
business plan if all broadcasters can use COFDM.

I have no clue as to what you are talking about here. I believe a smart
Wi-Fi radio can work at VHF, UHF and 5.8 GHz at the same time. Again
maybe my definition of Wi-Fi is to broad for you. The FCC seems to be
using the term in a broad sense that includes VHF.
