Mobile phone tracking is a technique that uses various technologies to determine the geographical location of a mobile device[1]. This tracking can be done through network-based technology[2], which uses the mobile network infrastructure to determine the device’s location. Handset-based technology uses software installed on the device and GPS signals to pinpoint location. SIM-based technology uses raw radio measurements from the device’s SIM card, while Wi-Fi-based technology uses Wi-Fi data for location identification. A hybrid positioning system can combine these methods for increased accuracy. However, the use of mobile phone tracking raises significant privacy[3] and legal concerns. Many countries, particularly in Europe, have strict laws protecting location data and the privacy of individuals. Despite the benefits of mobile phone tracking, such as aiding in navigation or emergency services, it’s important for users to be aware of potential privacy implications.
Mobile phone tracking is a process for identifying the location of a mobile phone, whether stationary or moving. Localization may be affected by a number of technologies, such as the multilateration of radio signals between (several) cell towers of the network and the phone or by simply using GNSS. To locate a mobile phone using multilateration of mobile radio signals, the phone must emit at least the idle signal to contact nearby antenna towers and 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.
Mobile positioning may be used for location-based services that disclose the actual coordinates of a mobile phone. Telecommunication companies use this to approximate the location of a mobile phone, and thereby also its user.
