    For the same reason that we see cellphones with built in media
    players and cameras and separate media players and cameras too.

    Because app accessible GPS isnt the same as what satisfys the

    Mainly because mapping needs a better screen than the smallest cellphone screens.

    There are satnavs that are otherwise as small as cellphones.

    > Why aren't better GPS features appearing in cell phones?


    They are, most obviously with the Nokia N95 which has full routing just like a satnav.

    You're just plain wrong. If that was true, they wouldnt be able to show the
    number of GPS satellites currently in view, and they can and do show that.

    Pity about the cellphones which have real app accessible

    That would figure; it should certainly be more visible and better

    Very nice. I hope they put in some of the other GPS features, but I've
    never heard of one that invites map data.

    Reasonable. But why wouldn't more cell makers try to build on that?

    That's strange, because I don't know how much you can lose of GPS
    ability and still get a location.

    You'd think so, conidering how much info a map has to offer. But some
    GPS are very low-res, even with map viewing.

    > There are satnavs that are otherwise as small as cellphones.

    Yeah, probably. The ones I know aren't the most expensive, and the
    smaller of the ones I know are arm-band units.

    But I'm still talking of the ones that don't, which seems to be almost
    every cell phone.

    Again, my statement was (very clearly, I thought) about the units which
    do not. Isn't that nearly all of them?

    Which apparently isn't needed. When my son loses his phone or himself,
    I can use an online service to query the phone for its location.
    It always includes an accuracy disclaimer, and displays the radius on
    the map. Sometimes, it's "within 17 meters" but others--well, on one
    occasion, if he had been choking, couldn't speak, and called 911,
    the EMTs would have had to search twenty square miles of residential area.

    because they aren't "full" GPS units

    Because some of us want a $50 cell PHONE, not a $500 do-everything.

    CDMA and iDen carriers decided to use GPS technology to satisfy E911
    regulations, while the GSM carriers went with tower triangulation.Of
    course, once the GPS technology was in the CDMA phone, it became real easy
    to sell third party apps that used the technology.

    GSM carriers showeed little vision with their decision to go with
    triangulation.

    What makes you think that it is a full GPS unit? It's quite likely that
    only partial GPA functionality is built into the phone.

    > Why aren't the cell makers building all GPS features into their

    See above- they may not be putting all of the technology into the phone.to
    take advantage of all features.

    > Why are all GPS devices larger (some by several times) than all cell
    > phones, when small size is just as useful to those?


    There are small GPS units available on the market.


    > Why aren't better GPS features appearing in cell phones?


    Maybe because it is a phone and not a GPS device as a primary function, and
    building in additional functionality would increase the size of the phone.

    Now you are assuming facts not in evidence. My CDMA GPS- enabled phone is
    just that- GPS enabled. How do I know? Simple- I've used the GPS app in
    areas where network triangulation is not possible and still received
    accurate positional data.

    When you say almost every cell phone, do you mean every ATT cell phone or
    every available cell-phone. I ask because ALL Verizon and Sprint phones
    come with GPS and the abiltiy to use the apps mentioned above. The fact is
    that almost every cellphone now comes with embedded GPS technology- it is
    simply the GSM portfolio that lacks this functionality.

    No, they mandated a way to locate the phone. The GSM carriers use
    triangulation, the CDMA carriers combine GPS and triangulation. Of
    course the system the CDMA carriers use is much more accurate, and more
    expensive. However the CDMA carriers can offer location based services
    that the GSM carriers can't, due the increased accuracy.

    I'm sure that the next generation of iPhones will add this feature,
    along with HSDPA. If not, there are other products, similar to the
    iPhone, that have these features already, but they don't have the
    marketing muscle of Apple.

    But the GPS functions are not user-accessable, are they? You need to
    pony up the $10/month for nav service, correct? Sprint and Verizon
    aren't going to let you dial up Google Maps and let you navigate for
    "free" are they?

    Depends on your POV, I suppose- EVERY GSM handset ever built works with
    the GSM tower locaation system. Sprint/Verizon had to force their
    customer base to upgrade to GPS phones and now refuse to activate older
    models in fear of breaking the 95%-enabled FCC requirement.

    One of the advantages of GSM, at least in my opinion, is the ability of
    the end user to choose any compatible equipment he wants, whether offered
    by the carrier or not. AGPS added even more handset-chioce restrictions
    to the already draconian US CDMA carriers.

    Even Windows Media Player can un-DRM a file by uncompressing/recompressing.
    The previous poster was talking about an algorythmic way to remove DRM

    I think the answer you might be missing is that, while the CDMA phones
    that Sprint and Verizon sell actually use GPS, it doesn't follow from
    this that the phones by themselves are actually "full GPS units".

    A "full" GPS navigation receiver needs to perform three functions:

    (1) Satellite acquisition, where the receiver discovers which satellites
    it can hear and approximately where the signals are located in time;

    (2) Make precision time-of-arrival measurements on the signals from the
    available satellites; and

    (3) Use the timing information from (2) plus knowledge of the locations
    of the satellites in space to compute a navigation solution.

    With CDMA phones, only (2) is done by the phone. (1) and (3) are done
    by the network. That is, the tower tracks which satellites are available
    and tells the phone where to listen for them. The phone makes the
    precision timing measurements on the signals it can hear and returns
    the results to the network. A processor in the network computes the
    location of the phone from this timing data. Note that the phone
    actually measures time-of-arrival not only of GPS signals but also
    CDMA tower signals, and sends the latter back too, so the navigation
    solution the network comes up with is actually a best estimate using
    both GPS and tower triangulation data.

    So, while the phones actually use GPS, the phones by themselves are
    not full GPS units and omit all the computing resources needed for
    satellite acquisition and the navigation computation. While the
    phone makes the GPS measurements the phone itself doesn't know where
    it is located (unless the network tells it). If the phone loses its
    connection to the CDMA network it loses the GPS capability entirely.

    See above. The phone itself doesn't include a full GPS receiver, the
    most complex functions of a GPS receiver are done for the phone by
    the network. The phone itself doesn't know where it is, and the
    network likely doesn't track the phone's location continuously either.
    The network only bothers to ask the phone to make measurements when
    the network wants the data, say for E911 purposes or to provide a
    location-based service which someone is paying the network for.

    No, CDMA phones really do use GPS, and really will get GPS accuracy
    when the phone is hearing the GPS satellites well (the latter is, however,
    a problem for the phones since their GPS antennas are likely less good
    than real GPS units, and the phones are less likely to be used where
    they have a clear view of the sky). The problem is your assumption
    that, because the phones use GPS, they must include a full GPS
    receiver and be able to autonomously support all the functions that
    real GPS receivers do. That's not true, most of the GPS functionality
    is provided by the network.

    Essentially because the cellphone market is dominated by very cheap
    phones and full mapping on cellphones requires quite a bit of decent
    hardware for the mapping function, storing the maps and doing the
    routing etc, quite apart from what provides the GPS location data.

    The Nokia N95 which has real GPS, not triangulation,
    and full mapping, isnt a cheap cellphone.
