摘要：This paper addresses a path loss prediction and optimization by means of Lee�s model for Jiza town, south of Amman city, Jordan. Data were collected from mobile companies in Jordan in the frequency band of 900, and 1800 MHz. The calibrated Lee�s, Hata, and Egli�s path loss models were compared with respect to the original collected data. It is found that for the 900 MHz Lee�s prediction model has the least RMSE among other compared models, and thus is best fit such areas. On the other hand, the 1800 MHz has higher RMSE deviation compared to Egli�s model. Therefore, to realize least RMSE, an optimization factor is proposed. A new frequency reliance of the optimization factor is reported; so as a frequency dependent relation is proposed. The new factor is justified in accordance with physical differences between the 1800 MHz and the 900 MHz propagation mechanism. After optimization, minimal RMSE value is obtained for Lee�s model, and examples are given for comparison.
