Abstract: Mobile location can be estimated based on Received Signal Strength (RSS). The RSS received from serving and neighboring Base Stations (BS) are used to estimate the mobile position which yields circles along which the mobile may lie. The circles intersect at the estimated mobile position. The RSS method is capable of being applied in existing systems without any hardware development. Experimental measurements of received power for the 900 MHz of existing GSM system are made. The RSS is used to calculate the distance between transmitter and receiver based on known transmitter power and transmitter location and an appropriate path loss model. Four different path loss models were reviewed; Hata Model, Walfisch Ikegami (WI) Model, ECC Model and Lee Model. Walfisch Ikegami Model showed the best result in terms of Mean Absolute Error (MAE) and is used to estimate the position location of the Mobile Station (MS).
