Track People Using Their Mobile Phones 257

Richard W.M. Jones writes "A couple of new services have been rolled out in the UK recently which allow you to track people when they have their mobile phones turned on. Mapminder states 'It's important to know where your loved ones are for your own peace of mind'. 192.com asks 'Do you want to know where your children are?'. Of course the police have been able to do this for a long time, and evidence from mobile phone positions has been used in high-profile court cases in the UK. Silicon.com has an article."

      A while ago, before 9/11 I was sitting in a bizare meeting with a bunch of wireless execs who were breathlessly telling us how great their new location finder service was going to be. They could send you adverts targetted at people in a particular location.

      I was rather unpopular when I asked if the customers would buy a product if the chief benefit was going to be to enable a new kind of spam. "Perhaps they don't get the choice"

      I was even more unpopular when I pointed out that the regulators in Europe would blast this type of thing on privacy grounds. "Oh the regulators tend to be more sensible than the general public".

      I pointed out that my cousin, one of those regulators has survived two assasination attempts and may have an opinion about a technology that gives away his position. In Europe privacy is not something that you muck arround with.

      Today the risk of this type of scheme would be obvious even to a US legislator. Now right to life will be able to stalk doctors who provide abortions by telephone, Saddam loyalists will be able to stalk senior Republicans and Al Qaeda will be able to stalk everyone.

      So they are finally working out socially acceptable ways to package up the same technology. Was it really necessary to have the dotCOM bust before some folk got a clue?

    Back around 1999 & 2000 there were rumours/news stories about the possibility of being tracked by mobile phones, and much discussion about how it wasn't really technically possible. Phone companies denied it could be done, many law enforcement agencies denied they used it (although some were forthcoming enough to say more). The general consensus was that it was something out of the XFiles.

    Now it's commercial a scant 3 years later. Who'd have guessed.

    • How does the fact that I left my phone at home while I was out committing prove that I didn't do it? This can be used to exonerate; it can only be used as part of circumstancial evidence leading to conviction if the criminal is stupid enough to carry his bugged phone with him. And anyway, how embarrassing is it when you're in the middle of breaking into a locked apartment, and you get a call from your mom? Oooh, I hate it when that happens!
    • Remember to leave your phone at home before you do your dastardly deeds. It will save the embarrassment of having to tense your hand in court so the glove won't fit.

      BTW, this post is assuming that the phone company is keeping accurate records of every place your phone visits. Having the ability to track phones does not mean that telcos are tracking every phone at the moment.

    During a family vacation in New England, we were driving on some windy mountain road somewhere near the border of NH and VT. We came across an accident (motorcycler ran into a tree). Well, there were lots of tourists there, and all had cell phones. But nobody knew where we were (not even which state, since we were near the border). Spent about 15 minutes arguing with operators who wouldn't send an ambulance without a specific location, while the guy lay bleeding on the pavement.

    That was about 10 years ago, but certainly shows how cell-phone signal triangulation can save lives.

    "Location based services" is the technical term. Basically the GSM provider can localize a phone depending on its last known cell contact. Phones in passive mode re-register themselves automatically only every half-hour or so, so the position is not up to date unless the person is using the phone to call or send messages. There is a kind of 'ping' SMS which just causes the phone to re-register and thus return a valid position. It only works if the phone is turned on (doh!). The whole concept is seen as a great money spinner by the GSM providers, but like MMS and other new gadgets, that is more optimistic than realistic. LBS is probably going to be most useful in chat and dating, allowing over-horny people (I suspect mainly gays) to find each other simply by tapping on their phone. The "find your loved ones" is a joke, no-one actually expects to use this to find their errant husband or kids - it's for dating, boozing, and possibly the return of stolen phones (the service I would most appreciate, having had 5+ phones stolen in the last two years).

    This is all pretty well known to those watching the E911 drama unfold.

    The easiest and simplest method for most carriers to comply with E911 is using triangulation. Indeed, bellsouth even posted a nice article about the various ways location can be obtained for cell phone users [bellsouth.com].

    Obviously, with a GPS stuck in the phone itself this becomes really trivial, but even with normal phones you can use a variety of techniques, like Time Difference Of Arrival (TDOA) and Angle Of Arrival (AOA) and even Enhanced Observed Time Difference (EOTD) to triangulate the location of a wireless caller.

    The carriers are already using this technology across the US, and many phones are now available with GPS integrated.

    Welcome to the future.

    • With the narrow channel bandwidths, TDOA is not going to work very well. But if you can get the phone to simultaneously transmit on 2 widely separated frequencies (maybe 1 on each end of the allocated spectrum), you could probably get it narrowed down to 10 meters if they are wide enough apart. AOA will do much better, despite being fuzzy at long distances, for routine tracking, but not to 10 meters.
