    The reason you can't remember where you read this is because it's
    utter nonsense. As of 12/31/2003

    * VZW had 37.5 M customers,
    * SPCS had 20.4 M customers,
    * ALLTEL had 8.0 M customers, and
    * USCC had 4.4 M customers.

    That's a total of 70.3 M CDMA customers solely from the top 4 CDMA
    carriers in the United States. This does not include smaller CDMA
    carriers (like Cellular South, Western Wireless, Rcc, etc.) or the
    vast amounts of CDMA users in the Asia-Pacific region and other parts
    of the world. Total worldwide CDMA subscribership is actually in
    excess of 188 M (see
    http://www.cdg.org/worldwide/cdma_world_subscriber.asp).

    While Cingular's GSM map is indeed impressive (at least in comparison
    to fellow GSM conglomerates T-Mobile and ATTWS -- mostly due to
    Cingular's generous roaming agreements with the aforementioned 2
    carriers as well as WWCA, Dobson, Centennial, etc.), keep in mind that
    there is no analog backup unless you get a GAIT phone and plan. Even
    with the included roaming coverage and a number of smaller providers
    switching to GSM, there are still vast areas that are analog only (NV
    is a good example, the state's prominent carrier - WWCA - is still
    analog only (although that may change within a couple of years)). If
    you truly need universal coverage (and I will admit that many people
    don't, but if you fall into the category of the most demanding users)
    then a GSM only phone and plan is not for you. Either go with a
    Cingular's GAIT plan or stay with VZW's America's Choice. Both
    options will allow you to take advantage of cellular analog systems
    where no digital coverage is available.

    Just so we have all the facts, this compares to 1,027million GSM users in
    2002

    From a *consumer* point of view, the main differences between GSM and
    CDMA can be summed up as follows:

    GSM
    ===
    * worldwide dominance leads to greater handset selection and cheaper
    handset prices due to economics of scale
    * same phone can be used in more parts of the world (assuming you get
    a quad-band world phone which are fairly common now)
    * slightly better sound quality due to superior vocoder
    * most GSM phones are digital only and do not allow use in analog only
    areas (GAIT phones are available from few carriers and are not very
    common and are being phased out)
    * higher likelihood of dropped calls due to hard handoff
    * inferior data offerings (GPRS is a joke and EDGE can barely keep up
    with 1xRTT rel. 0)
    * SIM card technology allows easy transfer of personal data from one
    phone to another but also creates a market for stolen GSM phones

    CDMA
    ====
    * better US coverage (at the moment)
    * most CDMA phones allow use in analog only areas
    * lower likelihood of dropped calls due to soft and softer handoff
    * vastly superior data offerings (1xRTT rel. 0 deployed nationwide -
    1xEV-DO being rolled out 2004/2005, 1xEV-DV coming shortly after)
    * stolen CDMA phones are largely useless - destroying any such market

    The page you're quoting speaks of "GSM Total Subscribers - 863.6
    million (end May 2003)". Are we looking at the same thing?

    I am not sure I understand your question. So I think the answer is no, we
    are not.

    I used:

    Hope that helps. Please understand that I am open to all opinions.

    As someone who has the luxury of both a quad band GSM and GAIT phone, I can
    assure you that they both have benefits.

    <snip>

    Good summary.

    Actually the slightly better sound of GSM is more likely due to the fact
    that GSM won't degrade the voice quality to increase capacity. The
    independent tests of CDMA and GSM phones show no difference in voice quality
    when the CDMA network is not cramming more users into the same bandwidth.

    International roaming is not an issue for most users. Personally I keep a
    GSM world phone around to use when traveling to Asian countries that are GSM
    (most of them, other than Korea and Japan) and I buy a prepaid SIM card. But
    if you simply must be reachable on your U.S. phone number, then GSM is
    indeed a better choice.

    I tried GSM in the U.S. for a year, but it was just horrible (Cingular in
    California) and it continues to be ranked as the worst carrier for my region
    (though AT&T passed it as the worst carrier in Southern California).

    The number of worldwide GSM users versus the number of GSM users is
    interesting, but meaningless. Even the GSM carriers are ultimately moving to
    a type of CDMA.

    My question (or rather observation) was in regards to the fact that
    you stated 1,027 M GSM users when the site you quoted as your source
    actually stated 863.6 M GSM subscribers, in other words the site you
    quoted to support your claim didn't support it.

    > I used:

    Clearly, that graph depicts total worldwide subscribership, regardless
    of technology used.

    > Hope that helps. Please understand that I am open to all opinions.


    Understood, but this is not a matter of opinion, numbers don't lie,
    it's either one or the other.

    Verizon offer a program with Vodaphone (one of their minority
    shareholders) You can rent a GSM "world phone" or just a SIM (if you
    already own an unlocked GSM phone). That way your US cell phone
    number will ring around the world, even with Verizon

    Indeed they do. International Traveler, I believe they call it.

    But if you can handle not being available at the main number, grabbing a
    rental or PAYG phone in Europe is a better option. And going with AT&T
    Wireless, T-Mobile or another US GSM provider that offers "world" phones and
    reasonable roaming rates is probably an even better option.

    I'm not a big fan of the GSM providers in this country, in general, as their
    customer service and coverage tend to suck. But international usage is an
    area where they probably do better than the CDMA carriers.

    I mean, I enjoy using my Verizon phone, but I don't think I can afford
    International Traveler.

    I apologize for the error. I misread the data. I assumed they were talking
    about GSM users, as it is a GSM related web site. That will teach me to read
    data more carefully.

    In the article it states

    "As part of the deal, AT&T decided to spurn Qualcomm's CDMA technology
    in the near term and build out a GSM network in the U.S. AT&T made
    this decision freely; they wanted the money from NTT Docomo, and
    moving to GSM and W-CDMA was the price they had to pay."

    Even though AT&T decided to spurn (what a weird word) Qualcomm's CDMA
    technology in the near term, I dont suppose (even if they have it in
    the back of their mind) they will switch to it any time soon.

    As you may or may not know the upgrades from GSM to W-CDMA is really
    just to a better version of GSM. W-CDMA = UTMS = 3GSM (3G GSM). In
    the mean time they have GPRS and EDGE upgrades to satiate some.

    Currently GSM uses a TDMA air interface, it transmits the over the
    air in TDMA, just as IS-136 (what is commonly referred to as TDMA AT&T
    and Cingular's old systsm) also uses a TDMA air interface to transmit.
    When the upgrade to 3GSM is done, GSM will use a more efficient and
    superior W-CDMA technology to transmit the data, but it will still be
    GSM.

    I thought about this a long time and could not come up with a good
    analogy but there goes. You can hit me over the head later

    Imagine GSM is a TV. and the TDMA and W-CDMA air interfaces are NTSC
    and PAL (not saying one of those is better) Which ever you use, NTSC
    or PAL, the end result is still TV. I know its bad.

    You're right, I can't come up with a better analogy, but the difference is
    that GSM is sort of an uber-protocol using either TDMA or CDMA as its base;
    TV has no such uber-protocol.

    GSM has only one (TDMA-based) air interface. There's no version of
    GSM that deploys a CDMA-based air interface. Perhaps you're thinking
    of UMTS.
