Mobile Tracker

Mobile phone tracking
From Wikipedia, the free encyclopedia
Mobile phone tracking tracks the current position of a mobile phone even on the move. To locate the phone, it must emit at least theroaming signal to contact the next nearby antenna tower, but the process does not require an active call. GSM localisation is then done bymultilateration based on the signal strength to nearby antenna masts.[1]
Mobile positioning, i.e. location based service that discloses the actual coordinates of a mobile phone bearer, is a technology used bytelecommunication companies to approximate where a mobile phone, and thereby also its user (bearer), temporarily resides. The more properly applied term locating refers to the purpose rather than a positioning process. Such service is offered as an option of the class oflocation-based services (LBS)[2].

[edit]Technology
The technology of locating is based on measuring power levels and antenna patterns and uses the concept that a mobile phone always communicates wirelessly with one of the closest base stations, so if you know which base station the phone communicates with, you know that the phone is close to the respective base station.
Advanced systems determine the sector in which the mobile phone resides and roughly estimate also the distance to the base station. Further approximation can be done by interpolating signals between adjacent antenna towers. Qualified services may achieve a precision of down to 50 meters in urban areas where mobile traffic and density of antenna towers (base stations) is sufficiently high. Rural and desolate areas may see miles between base stations
