Comparison of propagation models for fixed WiMAX system based on IEE 802.16-2004

Abstract

The study of empirical propagation models for mobile channels has been done extensively, but the applicability of those to a FWA System is not appropriately tested. The models include Hata-Okumura, COSTH1 Hata, Walfisch Ikegami and Erceg. From those, Erceg model seems to be the most suitable. In this paper field measurement taken for the 3.5GHz Fixed WiMAX network in Katubedda, Sri Lanka. Those are used to validate the applicability the above mentioned models in a Sri Lankan sub urban environment.
