    Hey guys,

    I didn't know if this was the right forum area to post this question but here it goes.

    Does anyone know how the hell the new maps application can triangulate a wifi signal and guessing your location magically??

    I'm really darn curious, because that is possible and explainable with a cellular signal because there are several antennas spread through the city/country/whatever and signal triangulation is done with the help of the antenna your connected and the closest one's. But with Wifi how can that be possible, nothing occurs to me and i'm a goddamn IT Technician/Systems Administrator with a good knowledge on wireless networks.

    This really makes me scratch my head

    I think Steve Jobs explained it during the keynote. There are towers and such from a company that locate where your iPod is or whatever...I don't know the details, and I don't feel like watching the keynote to remember what Jobs said, but its a pretty logical thing I know that, nothing fancy. Sorry for the vague information =/

    Its done with WiFi hotspots, not triangulation.

    That means if you are in a well covered area, it will be more accurate.

    Each wifi hotspot has a unique identifyer, and Apple have been given information on thousands of them. That said, its not working too well in the UK and other areas.

    EDIT: Not cellular Triangulation - it uses the hotspots to locate you....

    Are you sure the iPhones don't use triangulation at all?

    Ok my bad explanation, I was talking exclusively Ipod Touch.

    The iPhone will use cellular Triangulation, and will therefore be more accurate....

    Quote from Macworld:

    "The touch also gets the new ability to determine a user's location using nearby WiFi base "

    Yes, they use cell phone tower triangulation AND the wifi-hotspot location thing.

    iPhones use cell tower triangulation. For the touch, Apple teamed up with a company called Skyhook ?something?, which is a company that goes all over plotting wifi hotspots into their database. The iPod Touch then reaches into that database and triangulates from the closest ones near you.

    The iphone uses both cell phone triangulation through google and wifi triangulation through skyhook wireless. Since the touch doesn't have cell phone components, it relies on just the wifi triangulation.

    Does anyone know where we can go to get specific triangulation densities of the skyhook database? I'd like to see if this feature would even work for me, not living in a metropolis.

    If you're using a Public HotSpot it makes sense that Apple has a database with the location of the Hotspot but I'm talking about my own home Wireless Access Point, despite the fact I'm in Portugal(we don't even have "yet" the iPhone available in our country) .

    And how the hell can SkyHook Wireless have my Access Point location without my acknowledge?

    Found the answer to my question!
    You can go here to see where they have currently mapped out in the US:
    http://loki.com/how-it-works/coverage-area.php
    loki is a client app made by skyhook.
    Supposedly they have my location, but then, why doesn't it freaking work?
