By gathering a range of data from the mobile and the aerial, it could be possible to figure out the location of a mobile phone.
The mobile and aerial mast are both on the same clock and so you have the time it takes for the message to get from the mobile to the antenna (the delay between recieving
and sending data to and from each can be measured to give distance).
If it was possible (is it possible????) for the aerial to find the exact angle the signal is received from (to the closest degree) then these statistics can be put together in a kind of triangulation exercise to give us the location of the mobile in relation to the aerial. As long as you have available, the exact aerial location, then you can nearly pinpoint yourself to a place on the planet.
So, why would anyone want this, well if a computer program could be set up on the mobile network, it could calculate and send the user back the co-ords of their location.
These co-ords could be used by the user to find where they are on a map. So if your lost in your car, you just text the word "location name" to a special network provided number and it texts back where you are. Or text "location co-ords" and it sends back the co-ordinates.
This could be the basis for a system that provides location based services. The big thing the third generation mobile phones are boasting about.
Opinions, Criticisms, and compliments are all welcome!!!!
Please could you reference any sources?..so I can also go have a look at them...Thanks
