I'd prefer the Nokia 5165 TDMA phone over the 3360 TDMA phone as it has
slightly better reception. I can take both phones to the bottom of a
creek bed six miles from the closest tower and the 5165 can still hold a
call to 611, but the 3360 may not.

Although the map for the Dallas Statewide area states it requires a
Multi-network (GAIT) handset, some Radio Shack/Cingular affiliate stores
offer the Statewide plans with TDMA phones. Maybe because its not a
Cingular company store.

When I commented that there wasn't any GSM out there, I was referring to
that large areas in light yellow orange on their GSM map that shows "No
Service Area".
Now if Cingular is only licensed in the dark orange areas that show
current GSM coverage, but not licensed in the light yellow orange areas,
then you would be correct in saying Cingular is all GSM in Texas. The
point is, if a customer buys a Cingular GSM only phone, there will be
large areas where they won't be able to use it.

Some Radio Shack/Cingular affiliate stores offer the Statewide plans
with TDMA phones. Maybe because they are not a Cingular company store.

I would tend to agree with you. I was mainly referring to a post on the
AT&T Wireless NG that mentioned degrading TDMA service as GSM rolls out.

I pretty much figured this would be the case.

I've used Cingular's text messaging back and forth from my pager and it
is indeed VERY fast! The phone's user interface is much better than
Sprint's web based client for SMS. No waiting to log on, you simply
menu down to Messages and select Send Message.

I don't think thats going to be an issue with me as I've decided to
keep my two-way pager. I know it will always work in any major city I
travel to without worrying which carriers have text message agreements
in place. As for pager coverage in the areas I work most in, I installed
a 5 dBd gain colinear antenna on my car and drop my pager in a cradle
and it works great - way past the published coverage maps.
Let me snip from a post I made last month:

My passive repeater work extremely well.
18 dBd gain double bowtie arrays on chimney feeding a 12 dBd
colinear in hall closet with 30 feet of 3/8" Andrews Heliax.

I have both also and have opposite results. I think it depends on the
individual phone rather than the brand when comparing those two.

Very likely correct.

Most carriers are not licensed over the entire state, so all of C's network
is GSM by now. If they dont have service in an area, its because they cant.
Id like to hear more about your passive system. I think most folks assume
passive systems dont work because they really dont work, unless the antennas
are directional. If you have a passive system using whips, its not going to
make a lot of difference, but use something with good gain and it can make a
lot of difference depending on the system and setup.

JRW agreed:
Ok, that's what I thought you had in mind - Cingular would be 100% GSM,
but that leave a lot up to a salesperson informing the potential user
looking at the newest and greateest phone will be worthless in large
areas.
Providers are funny when it comes tossing around numbers. I believe it
was Cingular that boasted 98% (or some impresive number) of their CMA
(or some acronym that stood for the number of minutes in use in an area)
would be GSM by mid-2003. Not 98% of the geographic licensed area, not
98% of their subscribers - just total minutes used. Well in Texas, that
could very well be only five or six counties.

That's right. Most passive antennas have more loss in the 1/4" coax and
connectors than any antenna gain can make up for - but they might in a
situation where you simply need to get out of a Faraday cage.

Yeah, the percentage of minutes used does lend itself to use in urban areas
rather than rural.

I'm not certain what criteria you use with 'degrading TDMA', but
Cingular isn't adding radio channels for the gSM overlay, they're
converting TDMA channels to GSM, reducing TDMA capacity at every site,
although the remaining TDMA still works pretty well.

I don't think I've ever missed an SMS either. Often, when I get around
to turning The Beast on, sn SMS sent earlier comes through, apparently
having been stored until delivery was possible. Some folks have
actually complained of me not receiving an SMS from them, as they check
on the delivery status and are told 'not delivered yet'. This, of
course, compels me to explain that having a cell phone turned on and in
my pocket each and every minute of my day isn't something I consider all
that important. Then their mouths gape open as I say "I eventually
*got* their SMS when I and the phone were ready, so what's the problem?"
Some people still complain even if you hang 'em with a new rope.

Yes, the engineers are always going over the traffic numbers to see how much
activity each system is getting. As they see activity increase in the GSM,
the will accordingly alocate more GSM channels and delet more TDMA radios.
It will be a gradual (sp) change, hardly noticable. The phase out will be
sooner than most folks think.
