    yes they most certainly can, and do.
    which contradicts what you've said here and elsewhere.

    part of it is. not all of it. some comes from other users.
    yes they do.
    no bullshit at all. android devices use google's database and windows
    phone devices use microsoft's database.

    pretty straightforward stuff.

    why would apple's devices use google's database? it wouldn't.
    which is why it has a cached database in the first place, to speed up
    getting a location with a quick database query.

    assisted gps is separate and slower, however, it can be used to
    validate the wifi database.

    Yes, but there are still FAR more moving around
    in cars than there ever are doing that using trains.
    Far more do that from their cars.
    What matters much more than those numbers is the number driving
    around in their cars at each end and everywhere in between.

    Leaves those moving between NY and Washington for dead.
    Still **** all compared with those driving around in their cars.
    And when that is a major traffic route, a hell of a lot do that.
    Why wouldn’t it if it does when in a train.
    And yet I know that my wifi doesn’t get used like that unless the
    phone saves up all the bssids that it sees during the garage/yard
    sale run and then waits until I choose to use the apple store and
    adds the bssids to the traffic in that situation.
    Trivially easy to see what bssids move around a lot.

    Thanks for that completely superfluous proof that you have
    never had a fucking clue about even the most basic stuff.

    It isnt actually possible for an iphone in the wild to
    determine with any accuracy at all where a particular bssid
    is physically located. ALL it can do is determine where the
    iDevice is located and record that the wifi can be heard
    at that location and what the signal strength is there.
    **** all are.
    Wrong, as always.
    No such animal.
    No such animal.
    There are in fact a hell of a lot more of them than just those.
    Wrong, as always.

    And it isnt even possible for an iDevice to accurately
    determine where one of those is located. ALL it can
    do is determine where the iDevice is located and
    record that the wifi can be heard at that location
    and what the signal strength is there.
    It isnt even possible for an iDevice to accurately
    determine where one of those is located. ALL it can
    do is determine where the iDevice is located and
    record that the wifi can be heard at that location
    and what the signal strength is there.
    Have fun spelling out how it actually does that.
    Not unless you have access to that wifi. **** all do in most
    of the world were there is **** all free wifi and even where
    there is, the user has to deliberately log in to that.

    Wrong, as always. With no data plan you just pay for what data is used.
    Wrong as always.
    That's nothing even remotely like a plan, that's a casual data rate, stupid.
    Have fun spelling out how that is done. You can't, it isnt even possible.

    ALL it can do is determine where the iDevice is
    located and record that the wifi can be heard at
    that location and what the signal strength is there.
    It does to accurately triangulate when GPS is not available.

    You're lying thru your teeth as you always do when you
    have got done like a fucking dinner, as you always are.
    ONLY for working out faster which GPS satellites
    should be visible when the phone is moved a long
    way with the phone off or the GPS disabled, usually
    on a plane flight.
    That wasn't talking about getting an updated ephemeris,
    it was JUST talking about working out WHICH GPS
    satellites are visible at the new location.

    Everyone can see for themselves that it contradicts
    nothing at all that I have said here and elsewhere.

    Not for determining the location when GPS
    is not available when in a basement etc.
    Have fun listing where they do in what
    you previously quoted from Apple.
    But not for determining the location of the device when
    no GPS satellites are visible when its in a basement etc.
    Having fun thrashing yet another straw man ?
    How odd that none of google map,
    google, siri, apple maps do it that way.
    Wrong, as always. And that isnt assisted GPS anyway.
    Utterly mangled all over again.

  10. Didn't say 'world wide'. Whatever you tried to say, it doesn't refute
    what I said.
    Airplane mode importantly turns off sending signals. No harm in
    receiving them.
    You wouldn't know if your phone is silently, way in the b/g, receiving
    data from cell towers or WiFi when both are nominally off.

    What you said is irrelevant. Apple says they do that world
    wide and what you propose isn't possible world wide.
    Yes it does.
    In fact it turns off even the GPS which never sends anything.
    But the phone can't do that when its turned off in airplane mode.
    That can only happen if they are BROADCASTING the database
    because the phone can't say where it is or ask for anything.

    We know that neither the cell towers nor wifi is
    BROADCASTING that database in case someone wants it.

  12. How in the world would you know that?
    Not the database, silly, just the location data as to where the tower or
    base is.

    People who drive on some boulevard will all see some McDonalds BSSID at
    the same location and report it to be at same location. There may be
    thousands of such reports. But they all point to the same location.


    People who travel on trains report the same BSSID being in different
    locations at different times. So thousands report the same BSSID but
    they see it in different locations depending on where a train car is
    located when they report it.

    Because the Wi-Fi base station is inside the train car and travels with
    all the passengers so it is visible (and used by) passengers during the
    whole journey. Very different than driving by a Wi-Fi system and seeing
    it for 5 seconds before it fades as you move away from it.

    Because Airplane mode turns off the cellular antenna.

    Because we know that it turns the GPS off as well, essentially
    because its on the same chip as the radio and there isnt any
    point in leaving the radio receiver on when it can't transmit.
    That wouldn’t even be useful for SMSs, towers don’t broadcast
    SMSs in the hope that the recipient might be listening, they
    wait until the recipient shows up on a particular tower and
    then send the SMS to the recipient via that tower.
    OK, you didn’t say that clearly enough originally.

    Still won't work because phones don’t listen in
    airplane mode because there is no point in doing
    that, there is nothing being broadcast by towers.

  16. You do not know that the phone isn't receiving location data transmitted
    by the towers for just that purpose.

    Rod Speed Guest

    Yes I do, because there is no data transmitted by the towers
    for just that purpose, so there is nothing to listen for.

    What the towers transmit is very well known, because
    it has to be well known so phone designers could use it.

  18. Hah! You know this exactly how?
    How about a cite of a site or two?

    Rod Speed Guest

    Because what towers do is completely documented
    so that the designers of the phone know what they do.
    Hardly any of that documentation is free.

    All things being relative - xml is generally bloaty v. the data it
    represents.
    Should be. However there is a case for identifying the sampler in order
    to be sure the database uses several independent samples for each BSSID
    located. Would be nice to know more but there is likely no available info.
