What a GPS tracker can help you tracking people vehicle and cell phone

Mobile phones constantly emit what is known as a 'roaming signal'

, this is a signal sent out by the mobile phone that is used to determine which nearby antenna tower to connect to for optimum use.

By knowing the length of each line you can determine your exact position in the room. This is how reverse cell phone lookup service determine your position.

As the mobile phone user moves around the mobile phone tower to which they are connected changes also, switching to whichever antenna is able to provide the strongest signal in any given area, with this generally being the nearest tower located to the user. And so in this way it is possible to determine the approximate location of any mobile phone owner, as long as the phone is kept upon their person.
