Ah the irony.. does that advice apply to your posts too, John? Or just
everyone else? Pot.. kettle, etc.
Oh, and could you do that bit where you claim to be the technology-neutral
voice again? That one cracks me up every time.

Re: "GSM to overtake CDMA in USA"
Actually the reason I cite the impartial sources rather than
citing the GSM or CDMA trade association propoganda, as
John does, is that the trade association material is way too
biased (on both sides). Problem for the GSM camp is that
there is no impartial data that favors their position in terms
of spectral efficiency, as this would not be possible.
At least with the Deutches Bank study, both the CDMA and
the GSM trade groups claimed that the study favored the
other side and that their own numbers showed that they
each were better. That make me feel much more confident
that the Deutches Bank study was on target.

The Usenet Voice of GSM claimed that he was impartial?
ROTFLLMAO.
Personally I'd be quite happy if the whole world had
settled on GSM, but of course there are technical reasons
that are leading to the dominance of CDMA in one form
or another. If you want true 3G and enough spectrum for
voice, there is no alternative at this time.

Yeah.. here's the link (from this very thread no less!):

Since you also know John and his posting history, you know yourself why that
claim is so entertaining. And I never thought he'd say something better than

Gotta laugh when I look at the Sprint PCS map
for Montana. They have more alleged coverage
than even the FCC shows on AMPS A&B maps, yet
they have none of their own native coverage.
At least the GSM maps are not making claims like
that!.
You can see all the maps at:
"http://www.mountainwireless.com/maps.htm"
The FCC maps are PDF's from their web site.
"http://wireless.fcc.gov/services/cellular/data/AreaBoundaries-B.pdf"
"http://wireless.fcc.gov/services/cellular/data/AreaBoundaries-A.pdf"
Wouldn't want to be out in Montana without
AMPS! Of course if I go to Montana I don't want to
be bothered with a phone, so I guess it would be
okay to bring a GSM phone (or not, no difference).
For kicks, I should go to the Cingular or AT&T kiosk
and tell them that I often go to Montana and ask if
my phone will work there.
BTW, see "http://www.mountainwireless.com/cellmt.htm"
for information about Montana carriers and coverage.
You can see a detailed Montana map for Verizon at:
"http://www.mountainwireless.com/vzmtmap.htm"
I've added a section to my web sites for the best

Re: "GSM to overtake CDMA in USA"
Steven....gotta tell you that the mountainwireless site doesn't include
Missoula and the write up for Blackfoot telephone coverage is way toooo
generous. I had a lot of trouble with getting adequate analog service in
the city of Missoula let alone around the valley. Of course Blackfoot
offers pcs but not for Sprintpcs. Sprint admits no pcs coverage at all in
Montana when we got there.
The reality check from the Idaho line north to Butte had no coverage of any
type on I-15 and the analog only ran about 40 miles west on I-90 before
dieing out until you got inside the Missoula city limits. Just no signal at
all.
I was surprised 'cause I used to own a radio station there and had 2-way
coverage with my mobile for 120 miles around and cell was just plain non
existant.

You can see the spectral efficency numbers (impartial,
not from the GSM or CDMA trade associations), on page
51 at:
"http://www.sims.berkeley.edu/~paulette/courses/Spring03_HW/IS290_WirelessComm/2_Riseofthe3GEmpire.pdf"
I have a table with this data in the appendix of my sites,
you can go directly there:
"http://nordicgroup.us/ssub/appendix.htm"
Be wary of any "studies" from the CDMA or 3G trade
groups, or from equipment manufacturers on either
side.
TD-SCDMA may be a good technology to work around the
spectral efficiency issues of GSM, but as you stated, it will
not be as good as pure CDMA.

Be equally wary of material from interested parties with as axe to grind, as
is the case here, which is anything but "impartial."

Exactly. No one ever claimed that it was wise to _rely_
absolutely on a wireless phone for emergencies. But it's
just common sense to choose a service with as much
coverage as possible so in the event of an emergency you've
got better odds of being able to summon assistance. I've
used my phone on AMPS several times to summon help for
others or to alert the authorities of erratic drivers or
road problems. Not everyone is interested in becoming an
amateur radio operator.
I'd love to see the training materials for the carriers
that provide lousy coverage. This thread inspired me to
add a section to my web site with typical non-answers to
questions. Send me some good ones and I'll add them.

I did see that gem. Funny thing is, I agree with half of it. There are
places that
I don't want my phone to ring. But I want to be the one that decides for
this
to happen by turning it off. And even if it's off, if there is a situation
that requires
it to work so I can make a call, and there is coverage of some sort, I want
to be
able to simply turn it on. But as a rationalization of why it's okay to
select a carrier
with poor coverage, it remains a classic.
My other favorite, which the salespeople of the poorer carriers often use,
and
John has used as well, is the "no carrier provides 100% coverage" argument.
This is an attempt to divide the carriers into two camps, ones with 100%
coverage
and ones with < 100% coverage. Since all carriers fall into the latter
category,
ipso facto, they all are equal. Since you can't depend on either AMPS or GSM
to provide a signal no matter where you are, you may as well just choose
GSM.
The fact that AMPS provides magnitudes more geographic coverage is
irrelevant
to these people, as is the fact that TDMA and CDMA provide far more digital
coverage.

No, that "no carrier provides 100% coverage" simply means that there will
*always* be places where your cell phone won't work, no matter what the
technology (AMPS included) and no matter what the carrier (your buddy Verizon
included, notwithstanding misleading "Can you hear me now? ads). Thus, here
in the USA a cell phone isn't a terribly good *emergency* device, simply
because there are too many places where there isn't coverage (other than
perhaps in metro areas, although there are holes even in metro areas) -- you
may be able to call for help, but then again you may not. Different areas
have coverage by different carriers, and no one carrier works best in all
areas -- even if a given carrier has more coverage overall, that won't matter
if try to use that carrier in an area without coverage. The bottom line is
that cell phones are a convenience, not something you can depend on. If you
are truly concerned about being able to get help in an emergency, then you
need something better than a cell phone (e.g., satellite phone, personal
EPIRB*, SSB, even VHF).
