Mobile phone tracking - Wikipedia, the free encyclopedia



Mobile phone tracking refers to the ascertaining of the position of a mobile phone, whether stationary or moving. Localization may occur either via multilateration of radio signals between (several) radio towers of the network and the phone, or simply via GPS. To locate the phone using multilateration of radio signals, it must emit at least the roaming signal to contact the next nearby antenna tower, but the process does not require an active call. The Global System for Mobile Communications is based on the phone's signal strength to nearby antenna masts.[1]
