Discussion:
Loss of analog cell phone in remote areas?

Sometime next year analog cell phone service will cease and everyone
will have to use digital. Old analog cell phones will cease to work.

But will digital phones be strong enough to work in remote areas? As
I understand it, people in remote areas continue to use the older
analog 'bag" phones because they have a higher powered signal
necessary to reach the distant towers. Tiny digital handsets won't
have that capability.

Is anyone familiar with this issue and how it will be addressed?

It's actually more a function of the antenna than
power, but yes, it's a real issue.

(With the "bag phones" you could use a car rooftop
antenna. Since it was outside the car, and also had
a ground plane, it was much, much, better than
the stuff in your hand).

For the bag phones, the power out is also very important. The Bag phones
typically had a higher output than a handset phone.
Of course as cell sites decreased in size, and more cell sites were built,
the need for bag phones went down. Now they are used in analog systems where
a subscriber may be quite a ways away from the nearest tower.

Bagphones also come with whip antennas.

You can use a car rooftop antenna with digital phones, too, so long as
you have one with an antenna jack. I use a well worn but reliable
Nokia 6340 (in GSM mode, no service on TDMA or AMPS here) with the Nokia
car kit that includes cabling for an external antenna:

http://www.keep-talking.net/nokia_car_kits.htm

(It even has an optional handset, not illustrated here.)

You can also get signal boosters that splice into the antenna cable
and boost your power up to the 2 or 3 watt limit, e.g.:

http://www.cellantenna.com/Boosters/cellphone_signal_boosters.htm

All of these are intended for a car, but I don't see any reason you
couldn't build them into a bag if you really want something you can
lug.

Frequencies are neither analog or digital.
What I think you are trying to ask, is what about the cellular frequencies,
and how they are to be used.
How they are used depends on the plans of the operator.
Post by h***@bbs.cpcn.com

Again, that is not quite correct. Digital cellular systems use the same
frequencies as the analog systems. The digital systems are more efficient in
the use of the frequency in question. In other words for a given bandwidth
available to a carrier, by using digital techniques, more calls can be made
than would be possible using analog techniques.

Look at what the carriers are doing. They all have some kind of plan.
Going digital benefits the carrier and the public as a whole. In more rural
areas the need to go digital is not so pressing, so the uptake will be
slower in rural areas. And even that is not 100% correct, as digital offers
more functionality than present analog systems, hence analog systems even in
rural areas are migrating to digital systems.

It is my understanding that all US carriers are switching to wholly
digital because digital has more capacity than analog and they need
the capacity. That being the case, how will service in remote areas
be impacted? Others have noted difficulties with digital if there is
a long distance. Some have noted there are boosters or car antenni to
assist.

Correct. And again rural carriers may not go digital as quickly as their
urban counterparts.

Depending on the carrier, service to remote areas in regards to coverage
should not decrease. And in these remote areas you will may see a slower
change to digital

Proper system design by the carrier should overcome those issues.

What about services like OnStar that are based (at least in early
models, many of which are still on the road) on analog cellular?

I went to OnStar's website, which explains that, effective 2008-01-01,
you will no longer be able to get the service if your unit is
analog-only. They are offering an upgrade path for some older units
that are "analog/digital-ready." If you have the oldest units, built
before GM anticipated the end of analog, you're out of luck.

And yes, the FCC requirement is that, until 2008-02-18, "each cellular
system that provides two-way cellular mobile radiotelephone service"
must provide analog AMPS service. [47 CFR 22.901(b)] In other words,
starting next February, cellular providers are *allowed* to stop
providing analog service.

When someone I know asked about an upgrade for this, he was told that
the upgrade was to buy a new car. Seriously. :(

I hate to think what the OnStar users who have not been paying attention
will do when "I had an emergency, and it didn't work!"

I also wonder if OnStar has stopped or will stop charging their fee to
those users automatically on or before that time, or if they will use
the AOL model....

I think you're confusing analog AMPS phones with analog NTSC television.

But will digital phones be strong enough to work in remote areas?

But that is not the case. The FCC only stated that carriers no longer have
to support analog users. The users in question here are utilities, security
companies, etc that were using these analog systems to backhaul there
data,etc. This has only given the carriers the ability to now switch to
digital only. And this will require a buildout that many carriers have
already started.

In some areas with low power you will have major problems. There is
going to have to be a major add of towers or a change in how the calls
are handled by those towers.

Unfortunately its not just a problem of power output, for the systems
using GSM there are also timing issues involved that limit the maximum
range to about 20 miles. I've been in situations where I've had
plenty of signal strength but couln't establish a call due to this
distance limitation.

Good point. I hear that the GSM towers on the coast of Brittany in
France make the TDMA slot size double width so people on ferries out
in the channel can use them.

Yup, its called "half rate"- four timeslots/conversations per rf
channel instead of eight. The call quality dose'nt improve, the
regular CODEC remains in use, they just double the "cush space" for
incoming data bursts. Also used along remote highways but it's,
predictably, not as cost effective/profitable as "full rate" cells.

CDMA systems don't suffer from this so much, they have a pretty wide
timing window for the base reciever to lock onto & follow the mobiles
signal. On the other hand they do suffer from "The Mysterious
Shrinking Cell Site Syndrome". CDMA systems like everybody's signal
to arrive at the same level, to do this the systems commands
subscriber's phones to raise & lower thier output power so that the
base station receiver sees everybody the same. If there's someone
close in on a call who's phone's power output can't be commanded any
lower, & you're out in the boonies (with lottsa bars showing on your
screen) & your phone can't be commanded any higher, once the
difference reaches a critical level you'll be denied service. :(.

This can even happen during a call in progress :( :(

I miss my bagphone :(

US Cellular has a digital bag phone from Motorola. It is $529 full price
with a $50 rebate for plans over $39.99 and an $80 discount for a 2 year
contract.
