I'm led to believe that this is available commercially right now in the UK.

Anyone know where I can get it? Or a lead?

(This is the ability to triangulate the precise location of any mobile phone based on the amount of time it takes to send data packets two & from the phone from differing cells - accurate to around 50m. No additional hardware required)

Thanks all

I am not sure that it is Dolphin where/did have it on their network but i think it send data from a small GPS built into their cab mount phone...

However I have heard that Orange have some tricks up the sleeve..

Does anybody know what is happening to Dolphin. Last I read they had gone bust...

DavidLewis

Hehehehe,

Everyone laughed at me when I posted something similar on a recent "Big Brother" thread. Must be possible, although I have no helpful info, Puff.

DaveU

Apparently not available yet, soon tho... They're all talk, talk, talk these people

Dolphin have filed for protection against creditors while they restructure.

Puff, you been watching <B>Ronin</B>

Dunno how accurate this can be - i have seen quoted the cell (up to 60KM across, although down to hundreds of metres in cities), cell sector, hundreds of yards, and some "boffin" in Cambridge down to metres.

Still in the MI5/6 area at the moment? I am sure that civil liberties groups will win if it ends up being enforced in the commercial space.

GPS is probably a better bet at the moment.

To do it properly it is also dependant on the networks speaking to each other

There was a company trying to do it in the states but I don't have any detail on it.

Maybe something that you've seen before but there are more out there.

Regards Dolphin...

They've done exactly as DaveU have said but have a look at some of the figures around.

64,000 active units @ £25 per month + calls.

750 staff

Do a bit of multiplication, add offices, equipment, other costs & maintenance and then see whether income/outgoings are going to match & whether they can afford to pay back (or even service) the investment of several billion dollars to set the network up...

Someone is going to get a cheap network - if its wanted...

boomer

Puff,

are your after a cheap communications company, one that can track the location of mobiles (communicators), or a person tracking system???

Just wondering, 'cos they might be available separately.

Hi Puff

Not quite sure what it is you are looking for but one of the 'security' companies, I think it was Securicor used to offer a unit that went in a vehicle and like a pager that clipped on a belt that could locate using GPS to within a few feet. We tried to persuade our guys that it was fgor their own safety as the pager monitored movement so would detect when a lone worker had fallen off of a ladder (or fallen asleep )

carl

Don't know the commercial status, but Cambridge Positioning Systems have a system.

Luke

Thats why certain folk keep theirs turned off until needed.......
Stick a mobile under someones car and away you go!!

pay as you go can help until they matchthe number against you.

Long live ethe pager and land lines

Ok, here i go in waffle mode
As many of you may know, the transmitters used in the telecomms world for mobile phones are omni directional in most cases (not all but not going into that) so when a phone "tracks" it goes for the strongest signal but doesnt always get it!! this is due to a few things, one being if that transmitter has the maximum amount of phones taking up all the devices which are connected to it, it wont be able to talk to it. In this case it will "hunt" for its next strongest signal then connect to that if it can (otherwise it will give you the good old 112 calls only, to cut a short story even shorter).
You may not however be in a situation where you have 3 transmitters in the same area as you (any network) ie by the coastline etc where land ends or out of transmitter ranges.
It is however possible to trace which transmitter you are off but i feel it isnt possible to tri-angulate from this method remembering that transmitters can cover up to a 20mile radius in some cases!! most only cover around 5 or so to get complete area coverage for that network.
Sorry to have baffled you but the course was more interesting lol!

Please before you all ask, im not even going to go into the bandwidth, ie some networks use different bandwidths etc, your phone just "ignores" any other network.... (unless you go 999/112 in which case it is opened up to all)

Tony

Ps i also know that most phones are multi bandwidth anyway
