Many mobile propagation models are going under intensive corrections; recently, to suit other new criteria's such as rough terrain areas. This proposed model modifies Hata main urban equation by adding a formula representing a logarithmic linear regression estimator of the standard deviation (σ) of the measuring campaign path in Amman city, Madaba city, and Jiza town, Jordan. High correlation factor of −96.7% is calculated between excess measured path loss compared to Hata urban path loss and log(σ). Root mean square error (RMSE) difference between this model and the measured raw data path loss has overcome RMSE calculated for Hata model, by an average of 21 dB, for open areas. The correction of suburban areas is calculated, on average, as 20 dB, and for urban areas as 17 dB.
