Cell site analysis is a way of establishing the location of a mobile phone at a particular time.
Each time a phone is switched on, to access the Internet, to make or receive calls, or send of view texts or social media messages it connects to a network via telecommunication masts.
The location of the masts is recorded and can help determine approximately where the phone is and where it moves to.
