Abstract: A location finding system (100) includes a cellular mobile unit (102) a microprocessor (104) with communication port (106) and a remote dedicated server (108) connected via online data connection to the microprocessor (104). The system (100) can compute the mobile units (102) location in a very accurate way, using data which has been extracted from the mobile unit (102) by the microprocessor (104) without the need to Install any further hardware or software components Into the cellular network infrastructure. The location finding system operates based on the fact that in cellular systems, the cellular base station updates the cellular mobile unit (102) with the network's parameters. These include the ID of the current cell (112) to which the unit is connected, the ID and antenna sector of some neighbor cells (114) and the received signal strength, as measured by the mobile unit.
