So you can stop right there. As long as the spectrum is segregated that way,
among the different cellcos, it will be used in ways that benefit those who
paid the exorbitant fees, and not in ways that benefit the consumer.
This is irrelevant to the discussion. The fact is that most premium phones
today work with any U.S. carrier. Yes prices are higher in the U.S. than in
many other countries; the same can be said about the cost of almost everything
in the U.S.
That's one downside to having an affluent population. The taxes buried in
everything we buy is another factor. THis is especially;lay true for regulated
telecommunications services including telephony, broadband and MVPD service.
Within the spectrum the cellco owns. As long as this is the case, the cellcos
will need to accommodate peak demands individually, to maximize their own
revenues, EVEN IF there's a scheme which allows users to roam to other is
irrelevant to the discussion spectrum. Again, a this arrangement benefits the
cellcos and not the customers. The cellcos' only motivation is to maximize
profits, not to offer the consumer the most sensible connection.
Sorry, the telcos are not stupid, and they know what usage patterns look like
in the markets they serve, Most carriers share tower assets today. If a cell is
getting congested another cell is typically built, adding capacity for everyone
in that market.
The fact remains that the cellular networks, like the electric grid, are
designed to handle peak demand. There will always be unused spectrum during
off-peak hours.
The market will move toward sharing spectrum resources as the technology to do
so evolves. This is just Economics 101 - the carriers are not threatened by
sharing spectrum since they have us locked into contracts. They ARE interested
in reducing operating costs.
But you are WRONG about usage patterns (peak demand). This tracks
consistently across all carriers.
Again, words that say nothing.
But these words are correct. We do not have carriers that sell only to people
who work the night shift. The usage patterns for cellular service are very
consistent across carriers.
People move between cells. The ratio of users belonging to different cellcos,
within any cell at any time, will vary randomly. You are insisting on arguing
over obvious points, Craig. It just gets annoying.
Yes there will be a certain level of randomness at any given point in time; but
the fact remains that during weekday business hours ALL carriers see similar
usage patterns.
Again, there is NO correlation with TV broadcasting today.
The only point I made in this regard had NOTHING to do with ATSC 3.0. It had
to do with the way TV spectrum is allocated. All TV networks, and all TV
vendors, share exactly the same OTA standard, and have access to exactly the
same set of frequency channels.
This is not true.
We have multiple services in the TV spectrum; there are full power stations,
stations with highly restricted transmission masks so that they can be dropped
into areas where spectrum is scarce, and two classes of LPTV stations, some
still using the NTSC standard.
As the spectrum is allocated to these services to support public service goals
- re-electing incumbent politicians. And the stations are only charged minimal
regulatory fees - they are not paying to use the spectrum. Thus there is an
incentive to use common standards approved by the FCC; and we have seen several
instances where the government has mandated tuner requirements.
It is imperative that the politicians have access to every home, and that low
income immigrants be exposed to "American culture."
Yet there are no similar tuner mandates for radio; a manufacturer is free to
build a radio with AM, FM or digital tuners. Ironically, almost everyone in the
U.S. Use the radio service, while only a small percentage still use TV antennas.
The fact that ATSC 3.0 may introduce another transition is beside the point.
It will indeed cause a big waste in spectrum, for the transitional period, as
much as ATSC 1.0 did during its transitional period.
Why is this a waste? For the past few weeks you have been an "activist," coming
to the aid of the odor folks who will need to upgrade their ATSC 1.0 TVs.
What is remarkable is that you completely ignore the fact that broadcasters are
about to vacate another large chunk of the spectrum they once occupied. During
the NTSC-ATSC transition they had full use of ALL of their "beachfront
property" during the transition. This time they will need to use the remaining
spectrum far more efficiently in order to offer both ATSC 1.0 and ATSC 3.0
multiplexes during a transition; and there is no guarantee that many stations
will move to ATSC 3.0 at all.
This waste is trivial compared to the fact that three quarters of the
population does not use the TV broadcast service AT ALL.
But that's another discussion, and no one in his right mind would question
that transitional periods make inefficient use of spectrum. Analog shutoff
allowed for Ch 52-69 to be taken away from TV, while ever more programs came
available OTA. QED.
Yup. And the same will be true this time around because broadcasters will need
to use the remaining spectrum far more efficiently than in the past.
It's amazing what appropriately designed technology can do to change the rules
of the game. As Bob Miller just pointed noted:
"What took so long?"
