Evaluation and Performance Analysis of Propagation Models for WiMAX
Worldwide Interoperability for Microwave Access (WiMAX) is the latest broadband wireless technology for terrestrial broadcast services in Metropolitan Area Networks (MANs). WiMAX has potential success in its line-of-sight (LOS) and non line-of-sight (NLOS) conditions which operating below 11 GHz frequency. Estimation of path loss is very important in initial deployment of wireless network and cell planning. Numerous Path Loss (PL) models (e.g., Okumura Model, Hata Model) are available to predict the propagation loss, but they are inclined to be limited to the lower frequency bands (up to 2 GHz.
