Frequency analysis of path loss models on WIMAX

WIMAX signal throughput and area coverage range are the most important factors that will affect the quality of broadband access services in mobile systems. This paper presents a comprehensive study of frequency analysis for path loss on mobile WIMAX presented to achieve large throughput and wide coverage to a big number of users. In this paper we have calculated the path loss values based on the variation of WIMAX standard frequency in the range of 2 to 6 GHz, and a fixed distance of 5 km from the transmit station to the receive station in urban, suburban, rural and free space environments. The paper discusses and implements Okumura, Hata, Cost-231, Ericsson, Erceg, Walfish, Ecc-33, Lee and the simplified free space path loss models. All the models applied in this paper are used to predict the propagation loss for WIMAX.
