Mobile phone tracking is the technology developed to track or track the current position of the mobile phone even if the mobile phone is not in stationery position. The basic technology used is that the phone must emit a signal so that the nearby antennas can catch the signal without activating a call. Various technologies such as the GSM localization are used to track a mobile.
The advanced technology used to track the mobiles is to locate the sector in which the mobile resides and find the rough distance to the base station (from the sector). The tracking procedure depends on the base station because in rural areas there are a few base stations which mean that the information of the mobile phone will be precise.
GSM localization is the technology which it uses to track GSM mobile phones. This technology is broadly divided into three:
- 1. Network Based Localization system: Network based system exploits the network service provider’s infrastructure to track a mobile phone. One basic advantage is that the tracking system is independent of the handset. The major disadvantage is that if the base station is not located then the mobile information is not precise.
- 2. Handset Based Localization system: In a handset based system the software is installed in the phone itself and this technique determines the location of the handset by computing its location by cell identification, signal strengths of the home and neighboring cells. The major disadvantage is that the software needs to be installed in the system. Smart phones have the facility of installing software into it.
- 3. Hybrid Based Localization System: This system uses the network based as well as the handset based technologies.
