    PCS is a marketing term, in my opinion, but the FCC uses it too. But it
    just refers to the *frequency.* (1900 MHz)

    AT&T has marketed their phones as Digital PCS for years and they use TDMA
    (and now GSM), completely different cellular protocols, but they are mostly
    1900 MHz so the designation fits. Sprint is all 1900.

    No. Stop thinking of PCS as a separate protocol. The PCS frequency is used
    by GSM, CDMA and TDMA carriers.

    Verizon, Sprint, Alltel, and a few smaller carriers all use CDMA.

    PCS refers *only* to the fact that a phone is using 1900 MHz. It could be
    running on any of the digital protocols at that frequency.

    Exactly. Sprint took more time, so I wouldn't be surprised if they had the
    better service.

    Don't forget that US Cellular uses CDMA as well. So PCS is actually
    just a 1900MHz Frequency Subsidiary of a particular protocol?

    PCS doesn't mean a damn thing. Just FORGET that term.
    It's meaning has been totally blurred by all the marketing hype.

    When AT&T started calling their 800Mhz TDMA "Digital PCS"
    this screwed up whatever definition the term ever had.

    PCS was SUPPOSED to refer to any digital services in the 1900Mhz frequencies.
    NOT any particular protocol, "band", carrier, phone or whatever.

    Actually, wasn't PCS supposed to refer to any "Personal Communications
    System" no matter what frequency it was? This was even before the FCC
    auctioned off 1900 blocks.

    Assuming you can find someone else that has it. It's likely that
    the largest majority of true "business" users will stay with the
    NexTel unless Sprint severely undercuts on cost.

    I don't know if Nextel has any plans to deploy 1900MHz frequency since

    That's what I thought too, so when I saw AT&T claiming PCS on 800 MHz,
    I thought they were a little liberal in their terminology. Eventual
    research showed that PCS generically refers to an enhanced
    communications service (my words as I don't recall the exact wording)
    such as SMS.

    This was like seven years ago - about the same time Sprint hit
    the Dallas market. I believe AT&T is all 1900 MHz here now.

    Nextel uses two-way radio frequencies, not telephone frequencies. I am
    not sure, but I don't think that there is any spectrum for two-ways in 1900.

    That would not prevent them from developing a dual frequency phone- one for
    cellular and another for DC. They could then utilize 1900MHz and continue
    to use the two-way spectrum.

    I believe their proposal to the government regarding eliminating public
    safety interference asks for a swap to 1900MHz, IIRC.

    You're right. Its the different cell phone schematics. Also Verizon and
    Sprint use different framulators. But the biggest difference is in their flux
    capacitors... Verizon gets theirs from Yoyodyne in New Jersey...

    And they operate at 1900 "Gee-ga" hertz.

    Um.
    For PTT, not exactly. While they do both use CDMA, PTT is clearly not a
    switched network solution. It uses an SIP-based system, and both
    companies went with different vendors to provide this solution.

    It's also potentially on its way out. Nextel has made no secret of the
    fact that they too are looking into an eventual migration of their
    network to some variant of CDMA, including CDMA2000 1x.

    See:

    http://telephonyonline.com/ar/telecom_nextel_continues_pursuit/

    The current deployment of WiDEN is largely a stopgap to speed up their
    data rates, and while it *may* double their voice capacity (though
    they've seemed to not boast about it lately), they're still at a serious
    capacity disadvantage to CDMA.

    My point? As Nextel continues to see more customers sign up, service
    will degrade. And the long term solution is a costly transition to an
    incompatible standard, which will mean forced handset upgrades over
    time. And who knows? They may end up using an SIP-based system similar
    to what Verizon and Sprint are using now.

    SIP, huh. Session Initiation Protocol? Like, the same protocol many VoIP
    products use? Sweet.

    But I think this reply was to one of my posts, and I was referring to the
    fact that Verizon and Sprint both do use CDMA... ok, yes, PTT implementations
    may be different, but the networks are both CDMA networks.

    IIRC, and without more context it's hard to tell (and too late for me to
    remember), someone upthread said that PCS and CDMA were different protocols.
