Yes, that's the point I already made. On the other hand, wireless
systems that are dedicated to transmitting live broadcast TV to
mobile appliances, such as the much-ballyhooed DVB-H, do not
succeed, Craig.
We really have no experience with this in the U.S., but the
European experience has not been very positive.
Glad Craig finally got it. And of course we have experience. It was called
MediaFLO. One-way TV broadcast to mobile devices does not carry its own weight,
it seems. Even if the average man in the street, when asked point blank, might
claim to be interested in such a mobile TV broadcast service.
But your point about the World Cup reenforces the notion that
mobile broadcasting could be viable related to events with
large audiences.
Sure, on those occasions. That's why it makes sense for the cellcos to allow
for such eventualities, and LTE-A provides for this. The key concept being
"eventuality." And infrastructure designed to be two-way, and one way or
another, can also manage one-way service, if it makes sense for that time
window. That's the easy part, relatively speaking.
We have survived competing cellular standards in the U.S. The
shift to 4G LTE
... shift to LTE makes no difference. I already explained that. The different
carriers are still going to have incompatible cell phones, and are still going
to be able to dictate what features the customer can use. This is because it is
a system designed for collusion, rather than a system designed to give the
consumer what he wants.
In fact, let me take this tack. The OTA broadcasters should fight back to the
FCC. If the FCC is so interested in making the best use of spectrum, quit being
such hypocrites about it. The frequencies used by the broadcasters are NOWHERE
NEAR where cellular service is heading. Take a peek at frequencies being
discussed for 5G service. Anything remotely UHF about them??
And, how about repacking the cellular bands instead, which already operate at
reasonable frequencies for cell service? How wasteful is it to have to assign
completely separate bands to each of the cell companies? How well would that
have worked for OTA TV, Craig?
You still don't get it Bert. The Internet may well be uncalled at
the lower levels of communications, but the services enabled are
just as walled in as ever.
You have to be joking. Lucky for us, the Internet was not developed on the
walled garden model, which is why we have browsers on any PC which can use any
site out there. **Even if** sites are secured, any browser can be used, with
the proper credentials. The security protocols are also standard. This is how
the Internet evolved, Craig. Interoperability is THE PRIME CONCERN.
It is the limited little streaming boxes, and their smartphone-emulating
"apps," which are attempting to screw up a good thing. But note that
smartphones did not evolve as PCs. They evolved out of the cellphone industry,
a walled garden industry.
Funny, but radio broadcasting is surviving,
Not really, but to the extent that you are partially correct, the circumstances
easily explain why.
Radio is a service dedicated mostly to use in cars. When people drive, they
cannot interact with distracting services. So in cars, an audio-only, one-way
service makes some sense. **And yet**, Craig, very many people have stopped
using it. Why? Same reason that limits OTA 24/7 broadcast. Choice. The limited
spectrum limits choice. A two-way service provides users with vastly more
choice. Which is why services like Spotify and Pandora exist, and why some car
companies are embedding such receivers.
Broadcasting, in the technical meaning of the word, used to be the only game in
town, to deliver wideband content to masses of households. Telephone was a
coexisting two-way service, but it was severely constrained in bandwidth. That
has changed. Two-way service is no longer so severely bandwidth constrained.
This is the long and the short of it, Craig.
