It Takes Technology to Know Where You Are
With regards to Cell Tracking and Cell Phone Location, it was once that determining accurate location with GPS Global Positioning System technology required buying expensive and sophisticated software and hardware. Currently, complete solutions are available through cellular providers and the hottest smartphones.
A Smartphone is basically a stylish and refined two-way radio. Of course they don't work independently, they are a part of a cell network. At the heart of the system are towers and base stations, positioned into a network of cells, that send and receive radio signals. Cell phones include low-power transmitters that connect to the nearest tower.
As someone moves from one cell tower to a new, the radio base stations monitor the strength of the mobile phone's signal. As the cell phone goes toward the edge of one cell, the signal strength weakens. Concurrently, the next radio base station within the cell being approached calculates the strength of the signal increasing. As mobile phones travel from cell location, to cell postion, the towers exchange the signal from one to the next.
In remote places, cell towers may be too far apart to deliver a consistent signal. Even when cellular towers are plentiful GPS satellite signals could be interrupted by tall buildings, or mountains. Signals do not reach building interiors very well and sometimes people have a hard time receiving very clear signals inside structures, particularly inside elevators.
Even without having a GPS receiver, or when a satellite transmission is not strong enough, mobile phones will supply information regarding cellular phone position. This method of calculating cell phone location is called Triangulation or Mobile Location Services (MLS). Cell Tower Triangulation employs signal analysis data, including signal strength, to determine the amount of time it will take signals to travel from a mobile phone to a minimum of three cell towers to estimate cell phone accurately its location. There a variety of variables impacting computations and this specific technique is fundamentally less dependable than GPS methods.
To comply with Federal Communications Commission (FCC) specifications, cellular phone network carriers decided to include GPS equipment into cell phones, in lieu of revamp the cell tower network. But the GPS for most mobile phones are not like those in a regular GPS receiver which you take hiking or bicycling. Nearly all cell phones don't give the user direct access to the GPS information; reliable location estimation necessitates the assistance of the wireless system. Under FCC regulations for emergencies (e911) GPS data, is sent only during an emergency 911 call. }
Cell phones may have GPS and the device might "recognize" accurately its location, however it cannot "tell" anyone else its location, until connected to a cellular network.
It is important to remember that Wi-Fi complements the wireless network grid offering extra conduits for location information to pass along to the web. Mobile phones possess a unique electronic identifier and if enabled may pass this advice, finding mobile phones inside the geographical area covered by the internet hotspot.
Employing device GPS as a customer requires third-party technology to exploit features and functions inherent to GPS Mobile Phone Tracking and Cell Phone Location. There are various websites that include comprehensive tips relating to contending types of smartphone monitoring software packages, notably useful to android spy. They are able to do a great deal more than just track location, but getting an awareness of the factors behind location monitoring may be beneficial.
In general it is a matter of what location tracking system is available, and the need for accuracy. Hybrid methods are becoming available that use various techniques in tandem to provide best available location given available resources. It might be critical to consider how GPS location software applications handle the data and controls mobile phone settings. Having real time tracking on demand, or preferring to minimize battery use and data transmission should be expected. Generally the application determines the location with a GPS receiver and transmits the tracking data to a server through a cellular packet data connection. The data connection to the server is usually made over the Internet. How often GPS samples are taken and how often and by what method the data is sent to the server affect effectiveness and costs.

How would one go about setting up a large scale WIFI Grid?
What would be needed in setting up a wireless exchange that could encompass a radius of 1-2 km residentially and the hardware/software necessary to achieve that? and allow multiple (100+) different users at any one time. Capped download rates would be included. Really interested to hear what anyone has to say I have done a bit of research online but would like an expert opinion. Thanks 
Hi Adrian, thanks for that, I am at that stage and looking at pricing hardware and what particular products are available. Tower site and ISP supply is sorted. Any recommendations of suppliers or particular products?
You need commercial gear, with a few high towers and high end firewalls to do all that. Considering you are asking this question on YA here, I don't think you are ready to undertake such a a task. Even networking professionals will take a lot of time and effort to design such a system....
However, the basics are:
1) Talk to some networking professionals
2) talk to some ISP that is willing to supply your service.
3) Find several high tower sites and talk to the owners (unless you can put up your own towers)
4) Investigate higher end firewalls, like many Linux firewalls - come commercial, some "free" if you do it yourself
5) Investigate billing or accounting packages for internet providers, so you can bill your users. A free one is called ISPConfig
There's probably a lot more I missed, but start there....
