Location Estimation of GSM User Using Enhanced Tringularisation Method with Implementation of RF Fingure Printing
Positioning a mobile subscriber in a cellular network system remain challenge for law enforcing agencies and cellular operators as many users do not use GPS. According to an estimate, a precise GSM based position system incurs a high cost (approx. U.S. $10,000) per base station. This paper suggests an idea to estimate location of cellular user by triangulation method along with use of RF figure prints. As each mobile device monitors signal strength, this helps in assisting the network to take timely handoff decisions. These signal strength information is transferred to network via NMR (Network Measurement Report).
