Suburban Area Path loss Propagation Prediction and Optimisation Using Hata Model at 2375MHz

Abstract: This paper describes how Cost231 Hata’s model is chosen and optimized for suburban outdoor coverage operating in 2375MHz frequency band, Maharashtra, India. This optimized path loss model is based on the empirical measurements collected in the network focusing on the city Ambajogai, MH state. It is developed by comparing the calculated path loss from collected measurements with the well-known path loss models within applicable frequency range of WiMAX system, such as Hata, SUI, ECC 33 and Cost231 W-I models. The Hata model was 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. This optimized Hata model is implemented in the path loss calculation during the validation process. Thus, this optimized model is successfully improved and would be more reliable to be applied in the Ambajogai. WiMAX system for suburban path loss calculation & open urban path loss calculation in the 2375MHz frequency band.
