What equipment is used to find the location of a 911 caller from a cell phone ??

Cell Phones are now gps enabled.. 911 house option on most phones… What equipment is used to track 911 calls… and find the house… ?? Delight no math.. or trianguler answers.
I have a basic understanding of gps and loran C and lojack..
why cant we use the same system to track stolen phones…
or other illegal uses… and with this in house… we are ready for
cell phones to steer.. way points and all !!!

There is no way to clarify it without math or Triangulation. That’s what it uses from the transmitters to know your house.

There’s a way to clarify it by math and triangulation, but it’s simple to clarify.

When you are on a cell phone you are connected to cell phone antennas, often you connect to a few. Each one knows how far away you are from it, and if each one knows how far you are from IT, it’s possible to figure out everywhere exactly you are.

We can’t use the same system to rack stolen phones because nobody cares about stolen phones, I know you would want to find yours if it’s lost, me too, but in order to track a stolen phone companies would need to have access to the phone companies cell antennas (so they can see everywhere the phones are) and rent offices, hire people to run the equipment etc. they would have to charge a fee of course to take in that and make a profit. The end result would be that it would cost doubtless just over double the price of a new phone to track your stolen one.

Lojack do offer a laptop recovery service, it’s software that contacts lojack and tries to give lojack some hints about everywhere it is. But thieves don’t use your OS on a laptop, they sell it at a pub to buy crack, and the person they sell it to wipes it and reinstalls Windows, killing the lojack software.

OK to place it in simple form. Cell phones just like home phones have caller ID. A house phone can be tracked to an take up because it is registered with an take up. A cell phone that makes this call is “registered” with a satellite house. The satellite tower used can be lessened down to a general house and from there, by the math that you don’t want to hear about an exact house can be found.

Answer by the_mr911
911 centers cannot afford satellites in orbit, so they are not used at all. 911 callers are located by tower triangulation. The towers know everywhere your calling from based on distance.

Why does your mobile say it’s one o’clock, and my cell phone says it’s two o’clock?

*********************************

This is a prolongation of a series of subway photos that I started in 2009-2010, which you can find here and here on Flickr, and which I’ve continued — on a station-by-station basis — in 2011. The photos in this set were taken in the 181st IRT station, on the uptown platform, in February 2011.

********************************

Over the being, I’ve seen various photos of the NYC subway "vista," usually in a relatively grim, dark, black-and-white format. But during a spring 2009 class on street photography at the NYC International Center of Photography (ICP), I saw lots and lots of terrific subway shots taken by my fellow classmates … so I was inspired to start taking some for myself.

One of the reasons I rarely, if ever, took subway photos before 2009 is that effectively each such photo I ever saw was in black-and-white. I know that some people are fanatics about B/W photography as a medium; and I respect their choice. And I took quite a lot of B/W photographs of my own in the late 60s and ahead of schedule 70s, especially when I had my own small makeshift darkroom for printing my own photos.

But for most of the past 40 being, I’ve all ears mostly on color photography. As for photos of subways, I don’t feel any need to make the vista look darker and grimier than it already is, by restricting it to B/W. Indeed, one of the things I find quite intriguing is that there is a lot of color in this environment, and it’s not too hard to give some warmth and liveliness to the vista…

To avoid disruption, and to avoid drawing attention to for myself, I’m not by sparkle shots; but because of the relatively low level of lighting, I’m generally by an ISO setting of 3200 or 6400, depending on which camera I’m by. As a result, some of the shots are a small grainy – but it’s a compromise that I’m willing to make.

Thus far in 2011, I’ve been by a small, compact "pocket" camera == the Canon G-12 — in contrast to the somewhat large, bulky Nikon D300 and D700 DSLRs that I used predominately in 2009 anbd 2010. If I’m photographing people on the other side of the tracks in a subway station, there’s no conundrum holding up the camera, composing the shot, and taking it in full view of everyone. But if I’m taking photos inside a subway car or photos of people on the same side of the platform everywhere I’m standing, I naturally set the camera lens to a wide angle (18mm or 24mm) setting, point it in the general management of the subject(s), and shoot without framing or composing.

What I find most fascinating about the scenes photographed here is how isolated most people seem to be. Of course, there are sometimes couples, or families, or groups of school-children; but by far the most common vista is an individual standing lonely, waiting for a teach to arrive. He or she may be reading a book, or listening to music, or (occasionally) talking to someone on a mobile; but often they just stare into space, lost in their own thoughts. Some look pleased, some look sad; but the most common expression is a blank face and a vacant stare. It’s nearly as if people go into a state of suspended animation when they descend underground into the subway — and they don’t resume their normal expression, behavior, and mannerisms in anticipation of they emerge back above-ground at the end of their ride.

Anyway, this is what it looks like down underground … or at least, this is what it’s like in the stations I’ve visited and photographed so far. If I feel energetic enough in 2011, possibly I’ll try to photograph people in each subway station. It would be fascinating to see what kind of variety can be seen…

My boyfriend told me that he can track everywhere I am by by a GPS type thing on Google.

Answer by Tim S
He lied.

Some companies do offer such a feature, but it has to be enabled on the phone. Its usually offered as a way for parents to ‘spy’ on children. This is nearly always done on the carriers website, not google. Of course, not everyone can just look it up, but only the authorized users, who sit up the phone in the first house.

Google offers no service regarding looking up mobile locations.
