Abstract: “Propagation Modeling is required to provide a reliable and efficient planning of cellular network. In this Study, various propagation models like COST-231 Hata, ECC SUI are used to compute the path loss for WiMAX at 2.3 GHz in dense urban and sub urban environment. AWAS Numerical Method compares the path loss with these empirical models. The Path Loss by AWAS Code is appeared as very high because of the regular variations in Near Field Distribution at 2.3 GHz. It can be controlled by allowing the Near field distribution with a limited height of base stations.”
