मोबाइल फोन ट्रैकिंग एक हैप्रक्रिया।

Mobile phone tracking is a

process for identifying the

location of a mobile phone,

whether stationary or moving.

Localization may be effected

by a number of technologies,

such as using multilateration

of radio signals between

(several) cell towers of the

network and the phone, or

simply using GPS. To locate a

mobile phone using

multilateration of radio

signals, it must emit at

least the idle signal to

contact the next nearby

antenna tower, but the

process does not require an

active call. The Global

System for Mobile

Communications (GSM) is based

on the phone's signal

strength to nearby antenna

masts.
