Worldwide Interoperability for Microwave Access (WiMAX) is currently one of the hottest technologies in wireless; it’s a standard-based on the IEEE 802.16 wireless technology that provides high throughput broadband connections over long distance. The Worldwide Interoperability of Microwave Access (WiMAX) technology becomes popular and receives growing acceptance as a Broadband Wireless Access (BWA) system. Estimation of path loss is very important in initial deployment of wireless network and cell planning. Before any transmission and receiving we have to be analyses the path loss and delay at the different frequency range in the different area. 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). In the paper we describe the different propagation models which are suitable for work with WIMAX i.e. (cost 231 HATA model, ECC 33 model, ERICSON model & cost 231 walfish-Ikegami model) in non-los environment. Our main concentration in this paper is to find out a suitable model for different environments to provide guidelines for cell planning of WiMAX at operating frequencies 3.9 GHz. There are few proposed models which focus on frequency range at 3.9 GHz out of which we base our analysis. In this paper, we compare and analyze path loss behavior of some proposed models at 3.9 GHz frequency band.
