Abstract: This study presents an investigation of power received at 1800 MHz in a mountainous terrain. The net monitor software installed in NOKIA handset was used to conduct measurements of the received signal strength from fixed transmitting base station. Received signal strength measurements were conducted in Igarra, Ajaokuta and Okene from August 2007 to July 2008. The data was analysed to determine the propagation path loss exponent. The path loss exponent determined is 3.58, which is evident for the poor GSM signal in the mountainous environment. Empirical model (prediction) was proposed for the received power in the mountainous environment. The result of the Empirical model developed was validated by comparing with the measured values and an existing model. The result of the Empirical model when compared with measured values and an existing model (Egli model) showed a mean percentage error of 5.90 and 7.65%, respectively. The result from the comparison is satisfactory. Therefore, we can infer that the model developed to predict power received in a mountainous environment is very efficient.
