Propagation models are keys components of coverage planning. With the deployment of 4G and 5G network worldwide, operators need to plan the coverage of their network efficiently, in order to minimize deployment cost and improve the quality of service. In this paper, the standard model K factors is used to develop a method for tuning propagation models based on cross implementation of both particle swarm optimization algorithm and genetic algorithm. The data were collected on an existing CDMA2000 1X-EVDO rev B network in the town of Yaoundé, capital of Cameroon. The root mean squared error (RMSE) between actual measurements and radio data obtained from the prediction model developed is used to test and validate the proposed method. The values of the RMSE obtained by the new model and those obtained by the standard model of OKUMURA HATA in urban area are also compared. Through the comparison of statistics from optimized model and OKUMURA HATA, we can show that the method is capable to optimized propagation model and the new model has a better precision and is more accurate than standard OKUMURA HATA model. The new model is also more representative of the local environment and the proposed method can be applied anywhere to optimize existing propagation models.
