GPS Meets PCS

The Donald writes: "According to an article at News.com, Sprint PCS will be starting to implement E911 calls in Rhode Island sometime in October. The FCC required that all cell phone providers have an improved E911 system in place by October first. This is the first step in making the E911 a reality, with Sprint being the first major company to actually put a phone on the market that will work with E911; instead of just filing papers with the FCC saying the implementation is just to hard. The Samsung N300 phone will use GPS to track the people down. I like the idea, I just hope the phone will display the GPS information, and there is a way to opt-out for all of the location based advertisements you will get with your GPS enabled phone."

Now often this is enough information and we can easily respond to the call. However, if they tell us its after exit 31, and it turns out to be before exit 30, then that means we have to continue down the expressway, turn around at the next exit, circle back at least to the exit before the accident, then turn around again and get back on in the right direction. This has just caused a delay in our response by at least a couple of minutes which can often mean the difference between some insulation burning under the hood, or the total loss of a car.

  25. Real life story for why not to do that... by Controlio · · Score: 3, Informative

    Instead of these other posts that sound "nagging" in nature, I'll give you a real life story as to why these things once existed, and now rarely do.

    911 gets a call from a cell phone. They answer, and all they hear is a constant loud roar. After a minute or so of not being able to communicate, the line is dropped. The call comes in again, 5 to 10 minutes later. The same roar, yet no communication with anyone. The 911 operator gets curious, and makes a few calls. The line drops. Yet another call, minutes later, same roar, no human. A unit is deployed to find where this signal is coming from. Strangely enough the signal was traced to the Pontiac Silverdome (in Michigan, over 60,000+ seating).

    They traced the signal to a man who was watching a Detroit Lions game. The man was quite large, probably a little too large for the seat that was given to him. Anyways, his cell phone was pressing up against the arm rest of the seat, and pushing the emergency button every time he shifted. This story is true, and there are several of these stories in existance if you take the time to talk to 911 operators.

    This is the reason that cell phones now rarely have 911 buttons. This is also the reason most phones will now come with a "keyguard" function that ignores all button pushes until a certain key combination is pressed. It's just not feasible, with how easily buttons can be pushed in a pocket, on a belt, or in a purse. Cell phones may be good for many things, just not this.

With the help of the FCC and three trucks (or possibly with no trucks and good access to the cell towers), you can be tracked down with great accuracy. That's because your cell phone communicates with a base every few minutes - more often if you're traveling.

      At the other extreme you can have a tariff with "no contract", no monthly fee, no minimum spend, calls paid for in advance - and expensive calls.

      In between there are a large number of different plans.

      Generally calls are charged to the nearest second - but with a minimum charge - typically 1 miute. Some networks and tariffs have a very brief "free" period - something like two or four seconds. The idea is you don't get charged if you get answered by voicemail and don't want to leave a message.

      Incoming calls are always free for the person receiving the call. Expensive for the person making the call - but OFTEL are controlling this and forcing charges down - and have been for some time.

      Receiving SMS is free - but sending can be free or can be charged for.

      Network to Network calls can be hugely expensive - but OFTEL have just stamped on our mobile companies and are forcing them to reduce their charges.

      We have number portability - which means that if you change network (or tariff) you can take your number with you. This does cause problems because you are charged according to the network which receives the call - but portability means you can't determine which network you are dialling from the number dialled.

      Getting the right tariff can be tricky - but if you get it right the total cost can be very low. I currently pay £20 per phone per month - and get free voicemail, Calls I make when I am within about 5 miles of where I live are about £0.02 / minute billed by the second with a 1 minute minimum. Calls I make when I am outside this area are £0.09 / minute, billed by the second and with a free £16 included in the rental.

And just if you want a taste of the future, go visit the mobilePosition AB website (http://www.mobileposition.com), which was also recently acquired by SignalSoft. Ever wanted to know where your friend was? Well, sooner or later it will probably happen.

And those PDEs can be tapped before our software even gets its hands on the location data. Our safeguards will do nothing to stop a cell phone company from tracking you. They will only prevent our software from doing so.

    So, here's the scoop. If you are worried that you are worth tracking by powerful government agencies or very, very rich people, do one of two things: A) don't carry a cell phone or, B) take the battery out of your cell phone. B) is not foolproof, but it should be good enough until cell phone manufacturers are required by law to include a small backup battery in the guts of a cell phone large enough to run a GPS receiver. Fortunatly, current batteries are very bulky and expensive, and including a nonremovable secondary one in cell phones big enough to run a GPS receiver is likely to be many years in coming.

Even without a SIM card inserted in the phone. This is a legal requirement and seems to be a feature built in to GSM itself.

    Due to the very precise time division multiplexing used with GSM, the distance you are from the base station you are currently subscribed can be gleaned down to a metre. If they can force your phone to switch to 2 other cells after an emergency call, they could probably pin point you without GPS.
