    The reason TDMA sucks in NYC is because the inefficient spectrum utilization
    of TDMA makes is particularly poorly suited for high density population
    areas. AT&T is not spending any money to expand their TDMA network, to the
    contrary, they are converting more and more of their spectrum to GSM. Alas,
    GSM is not nearly as spectrum efficient as CDMA either, so Verizon will
    remain the number one carrier in NYC for the foreseeable future.

    Cingular TDMA does not suck, at least not yet. And of course there is no
    Cingular TDMA in NYC.

    You can see the relative spectral efficiencies of the different technologies
    on page 51 of:
    http://www.sims.berkeley.edu/~paulet...90_WirelessCom
    m/2_Riseofthe3GEmpire.pdf
    and understand why that even the GSM carriers are eventually moving toward a
    version of CDMA (W-CDMA)..

    In most areas the spectral inefficiency of TDMA doesn't manifest itself
    because the areas are not densely populated. But in crowded areas it is a
    problem. Even in the San Francisco Bay Area, the first GSM provider,
    Cingular, had severe network congestion problems due to over-selling their
    service, a situation that would have been avoided had they chosen a more
    spectrally efficient technology.

    Ten-twenty years from now all the carriers will be using CDMA and network
    congestion problems will not be as severe.

    You've never used Sprint PCS in Chicago then!!
    I have T-Mobile corrently... I've had every other carrier that's ever
    marched in Chicago... They've all sucked in my opinion... As much as I use
    the phone, I only have two dead zone, and 3 spots that are kinda shady...
    But for the most part Crystal clear

    Cingular's TDMA in the Dallas market is horrible. AT&T is better than
    Cingular but then again even SprintPCS is better than Cingular in the
    Dallas area.

    The practicalities of spectrum aside, anyone who does a side-by-side
    comparison of Verizon service and TM in NYC will be sorely
    disappointed. There's becoming nothing more frustrating than a call on
    the other end with a Verizon Wireless customer. It's becoming as bad
    as AT&T's TDMA.

    Now, many of the people I know who have Verizon don't have the latest
    handsets and that may be part of the issue.

    Can't comment about AT&T TDMA in NYC, but AT&T's TDMA service is probably
    the best coverage you'll find over most of the country. That's why most of
    the small independent prepaid resellers go with them.

    Not because it makes the best financial sense?

    If AT&T is so great why are they losing so many customers since 11/24?

    Mostly because of both- excellent coverage with roaming agreements already
    in force for most of the country, and because AT&T at one time encouraged
    resellers as a source of revenue. (AFAIK, they no longer seek out reseller
    relationships, but entertain the existing ones out of contractual
    obligation.)

    > If AT&T is so great why are they losing so many customers since 11/24?


    Because they are rushing the switch to GSM, and not focusing on maintaining
    their once excellent reputation for coverage.

    Cingular is in a similar boat, but doing a better job staying afloat- they
    too are transitioning their TDMA customers to GSM. Unlike AT&T, however,
    Cingular has relied heavily on GAIT phones- TDMA/GSM/analog combo units-
    that allow their customers to reap the coverage benefits of the mature TDMA
    network during the transition, and aren't going out of their way to wrench
    TDMA phones out of customers hands- instead they are playing it much like
    the analog to TDMA transition- they aren't forcing anyone to switch, rather
    they "encourage" migration to GAIT by offering special rate plans available
    to GAIT customers only, and figure the average customer's propensity to
    upgrade phones every few years will take care of the conversion for them if
    only they are patient.

    AT&T, instead, pushed the "gee-whiz" of "mLife"- the wonderful advantages of
    GSM picture phones and GPRS data, long before their GSM coverage was ready
    for prime time, resulting in migrating customers losing a lot of coverage,
    and new customers wondering where the reputation for ubiquitous coverage
    came from.

    Hardly. Possibly W-CDMA / 3G technologies, but not CDMA itself

    IOW they DON'T have the best service. No one really cares what they
    used to have.

    And in at least one market, NYC, they never did have anywhere near
    best, or even excellent, coverage. It was more like "if you're not in
    a dead spot ("spots" being miles in diameter), and it's not a heavy
    usage time (like 5PM or the weather is bad), the signal doesn't suck
    too badly" coverage. Which is why they lost me as a customer years
    ago. And which is why they're losing customers in the NYC market to -
    believe it or not - T-Mobile.
