In wireless communication, the path loss exponent has a strong impact on the quality of links or signal, and hence, there are needs to accurately estimate the efficient design and operation of wireless network. Many research efforts have been devoted to modeling the path loss propagation effects for narrowband communication systems by using different methods ranging from analytical models, semi-empirical models, to empirical models. Telecommunication industries today have a major problem which is losses that occur during transmission of signals from the transmitter to the receiver. In this thesis, the empirical method was adopted though it is so stressful because it involves the measurement of large data, with the help of a software called RF signal tracker which was installed in a mobile phone called Samsung galaxy pocket, this software gave us the distance to site (base station) and the signal strength level of the network provider at a particular distance. A fixed distance was taken from the base station to the receiver and in this research work a particular fixed distance was taken as 100m from the base station which was represented as d0 and a variable distance which was represented as di. From result than the existing ones, and that the path loss exponents of the tested locations was fully known. A mathematical model was developed to calculate the power received of GSM signal in Ekpoma and the model was named Anyasi’s model”. From calculations the path loss exponent values were 1.48, 1.34, 1.11 and 1.48 dBm respectively for the tested locations namely; College of medicine, Ambrose Alli University, Ekpoma, Ujoelen Ekpoma, Eguare Ekpoma and Emaudo Campus, Ambrose Alli University, Ekpoma. Comparing the signal strength obtained from the generated model and the measured signal strength obtained from RF signal tracker, it was observed that they are almost of the same values my data, it was observed that the calculation of path loss with log – distance model which is deterministic is not as accurate as the empirical model (generated model), the generated model gave a better and more accurate
