Abstract: Radio frequency optimization is an important process in verifying and monitoring the performance of any GSM radio network already deployed in an area. It is a periodic activity that is done to maintain a good radio quality of service and enhance end user’s perception. This study describes a study on radio frequency attenuation path loss behavior in suburban and rural coverage of Ekiti State in Nigeria. The objective of this study is to develop and optimize a path loss model based on the existing path loss model and outdoor measurement using at 900 and 1800 MHz Measurements of received signal strength were taken in some base stations in the 16 local governments of the state along the propagation paths. Specifically, five path loss prediction models namely free space, Hata, COST-231 Hata, Ericsson and Egli were used to predict path losses. The Hata Model and COST-231 Hata Model were chosen as a reference for this optimized path loss model development based on the closest path loss exponent and smallest mean error as compared to the measured path loss at 900 and 1800 MHz, respectively.
