Wrong. Read through it, don't just scan the first paragraph as you usually do.
The scheme stinks of collusion. Its designed promotes collusion.

Yup. THe business model that they are now being forced to adopt
for very practical reasons. It mad sense to let third parties buy
the tower assets so that all carriers can use the vast majority
of existing towers.
No, you missed it. The separate companies were allowed to invent different and
incompatible digital cellular schemes, by the FCC, in the interest of
"innovation." That's why Bell Atlantic, at the time, went big time with
Qualcomm's CDMA, as opposed to the older TDMA used by others, including
GSM-based service. Anyway, whatever the history, the different carriers own
their slices of spectrum in the US. In principle, we could have a more European
approach to this. There is indeed no sense having to deploy different slices of
spectrum in each cell, only because different carriers are sharing a tower. I
mean sure, sometimes the traffic load will warrant this, but often it just
creates waste. If "repacking" makes sense for OTA TV "repacking" makes **even
more sense** for the cell carriers.
So Bert. Is WiFi such an International standard?
WiFi consists of local hot spots, to extend the coverage of a local broadband
connection. Think of WiFi as nothing more than a big honking Ethernet layer 2
switch, Craig. Think of it as a local fan-out box, to feed multiple devices
from that one broadband modem (broadband modems are also IP routers). That's
all it is.
WiFi was not designed to provide seamless wireless access in large geographical
areas, as OTA TV and cellular telephony must do. So the situation is totally
different. But yes, WiFi is an international standard.
WiFi operates in unlicensed spectrum. It is an unregulated service.
Craig adds 2 and 2, and gets 6. As often happens, Craig, you are confused. WiFi
hot spots can operate "anywhere," in the sense that if they interfere with each
other, too bad, so sad, no one else gives a damn. Use of licensed spectrum is
instead intended to avoid this mutual interference problem, so that the service
is GUARANTEED to work. BUT, in spite of this, WiFi access points have to meet
the IEEE 802.11 standards. There's an organization to ensure that they do. You
can't legally buy a WiFi access point that transmits 1000 W, Craig.

And speaking of fiefdoms, that term does an admirable job of
describing TV broadcasting. In many countries the government
operates the fiefdom;
Perhaps, but I can easily buy a TV set that is compatible with every single OTA
TV tower out there, Craig, and the TV networks share the same TV band. I don't
need a different TV to watch each network, and the TV networks do not need
multiple frequency channels, to get access to every TV set in the market.
I'm finding myself, as always, having to belabor the obvious for Craig's
benefit?
But there are millions of folks out there in the U.S. without
Internet access
Broadband will become a lifeline service, we are told. So, not a big deal in
the long run. And your PC can then access any site, even pay sites. How you pay
the site is a totally different matter. Don't waste my time with silly
arguments, Craig. Pay with a money order, if your must.
There is no reason - technically - that local broadcasters cannot
be in BOTH the FOTA and on-demand content businesses.
The very clear majority of TV is being consumed on demand. In spite of the
propaganda we read, ATSC 3.0, as it is being developed now, as is described in
the standards written so far, is purely a one-way broadcast medium. Therefore,
in spite of the (deliberately) misleading words, ATSC 3.0 is not designed to
offer TV the way most of it is being consumed. At best, it can be used to feed
PVRs, as a work-around measure, to provide emulated on demand service.
Stick with technical realities, Craig. Going off on nonsensical tangents is
just a waste of words.
Bert
