    Has anyone heard anythng about Sprint using the CDMA technology on their
    newly aquired Nextel frequencies?

    No. Has the FCC even said such use would be permitted?

    That's a definite no, at least for the next few years. Sprint has
    committed to continue iDEN support until at least 2010. Given that iDEN
    is spectrum-hungry, Sprint cannot really deploy CDMA on 800Mhz without
    decommissioning iDEN first.

    Further, there's rumor and sepculation that Sprint intends to SELL the
    iDEN infrastructure, including spectrum, to the federal government after
    the 2010 date, in exchange for spectrum in higher frequency ranges (2Ghz
    and up). The speculation is that this is for future WiMAX development.

    Either way, it's unlikely you'll see CDMA for Sprint on 800MHz anytime
    soon, if at all. Unless they acquire a traditional cellualr company
    with an A or B block license.

    I can't see how this could *ever* happen. Unless I grossly misread
    something, Nextel entered into an agreement to abandon that spectrum in
    exchange for a greatly reduced price on spectrum at 2.5GHz.

    As I recall, that's one of the precipitating events that led Sprint to
    "merge with" Nextel. And yeah, as Isaiah said, this was to support
    anticipated rollout of WiMAX in the future.

    As I recall, anyway. I'm trying to locate, without luck, the sources
    that led me to believe this.

    It might be a good idea for Sprint not to launch iden on the new
    frequencies, but go straight to cdma.

    Unfortunately, the Nextel push-to-talk feature does not work as well
    on CDMA, and Sprint would piss off the Nextel customers who depend
    on low latency PTT.

    EVDO Revision A is slated to fix the latency problem.

    By the time the new frequencies come into play (again, as I understand
    the plans), it'll be a moot point.

    What I understood is that those new frequencies will be used for WiMAX,
    and "cellular/PCS" service, including iDEN, will stay at 1900.

    If, that is, WiMAX pans out.

    Nextel has been under fire in Philadelphia because our Fire Department's new
    digital communications system seems to be blocked whenever a firefighter
    tries to go on the air while in proximity to a Nextel tower. Motorola, who
    engineered the fire dept communications network, has been unable to explain
    what is going on. All we know is that firefighters' safety is compromised
    when they can't transmit or receive while in burning buildings.

    There was talk about the FCC giving Nextel a different frequency spectrum
    (this was pre-merger). I don't know what the current status is. The Fire
    Department says only that there is a correlation between communications not
    working and the existence of nearby Nextel towers. Motorola won't admit
    fault, but they can't fix the problem, either. Nextel was denying any
    responsibility, saying that they were in full compliance with FCC
    specifications.

    I'm not surprised. All you need is a set of stereo speakers, and you'll
    be able to detect an active Nextel phone from 10 yards away. iDEN gear
    is notorious for the amount of spurious RF interference they spew.

    > There was talk about the FCC giving Nextel a different frequency spectrum

    The current status is that the FCC is going ahead with Phase one of what
    it calls "re-banding." In other words, Nextel is being forced to swap
    licenses with law enforcement agencies and other licensees in the same
    800MHZ bands so that Nextel is as far as possible towards one end or the
    band, while the public safety agencies are at the extreme other end.
    The hope is that if the two networks are kept as far away from each
    other ass possible, the interference and blocking issues will diminish.

    The drawback of course, is that while most Nextel handsets were designed
    to be all over the 800Mhz SMR spectrum if need be and thus need very
    little intervention to allow this to happen, most public safety agencies
    have gear that was specifically and permanently tuned to a very narrow
    set of channels, and they now have to go through great expense to get
    their radio gear re-tuned to whatever new frequencies they're assigned.

    Being FCC compliant doesn't mean squat. All one needs to do is put a
    Nextel phone near a monitor or a set of speakers, and then make the
    phone ring, to see what I'm talking about.

    Try that with alot of phones and not just Nextel and you will hear it.
    Actually every phone I have ever tried it with will do it except
    Verizon/Sprint CDMA phones.
