Now see Thomas, you don't understand. When Navas says he got his
information from a professional or describes his personal experiences,
its perfectly acceptable as the gospel truth.

Re: How Is CDMA Superior To TDMA?
CDMA is far superior to TDMA. As I have stated in another forum, the CDMA
and GSM debate reminds me of the Beta versus VHS debates that occurred in
the 70s. The Beta Tape Standard was far superior to the VHS Standard, yet
the VHS Standard was chosen and adopted. GSM provides less capacity and
lower data rates, yet it is the world standard simply because it was
accepted first and was an easy upgrade path from TDMA. Unfortunately, the
world is now stuck with a sick and crippled dinosaur. A little forethought
could have prevented this problem. :-(

No- you are wrong and can post no evidence to the contrary. CDMA now covers
most of rural america- GSM does not come close. But a nice try by the
uneducated to skirt the facts.

The GSM footprint is smaller than the CDMA footprint, but the real
difference is in CDMA+AMPS versus GSM. GSM carriers will often cite the
population that they cover since the rural footprint covers so few
people that it's lost in the noise.
Unfortunately, GSM customers _do_ suffer from this lack of coverage when
they travel to, or through, these areas. I've seen this first hand when
I was vacationing in an area with no GSM coverage. GSM and iDEN users
were SOL, while CDMA, TDMA, and AMPS users were able to make calls. The
situation in that particular area has improved somewhat for GSM users,
as coverage has been added in the metro areas, but they still have far
less coverage in the rural areas.
GSM shills will also often incorrectly state that AMPS will be turned
off in 2008. In fact, the carriers are _permitted_ to turn off AMPS, not
required to turn it off. In areas with no digital coverage, which is
actually the majority of the land area in the U.S., AMPS will remain in
place.

Forever is a long time. Whether it's W-CDMA or CDMA2000, the world is
moving to CDMA eventually. Voice will follow data.

Carriers, at least AT&T does, uses the number of minutes used instead of
population/subscriber numbers to reflect what they want to present. I
posted the acronym used last year, can't remember what it was. It was in
an AT&T article describing the roll-out of GSM and how large the
coverage would be.

So AMPS can't go away, or OnStar is out of business on Feb 17, 2008

Only the older OnStar vehicles. GM now uses CDMA/AMPS on newer vehicles.
However the usability of OnStar will be reduced if AMPS goes away.

Re: How Is CDMA Superior To TDMA?
The older phones/cars use AMPS, but the new plans/car/phone are digital,
usually CDMA.
My wife caller her parenst car through on-star and it's billed as mobile to
mobile.

Which carrier does she use?

Verizon, sorry thought I put that information in the message.
Sprint CDMA, not in my area or my lifetime.
