Accurately determining the locations of all mobile phones used in a country is achieved through a process that utilizes data provided by mobile operators. In this system, mobile phones regularly measure signal levels from multiple base stations, collecting data that is then transmitted to the respective mobile operator. Through sophisticated analysis of this data, the phone's location can be precisely estimated using fingerprinting methods. This method involves comparing the unique signal characteristics observed at different base stations, allowing for the creation of a distinct fingerprint for each location. By leveraging these fingerprints and employing advanced algorithms, the system can deduce the geographical coordinates of mobile phones, providing a reliable and effective means of location tracking.
