It is a challenge to the wireless and networking engineer to decide upon the path loss model applicable to the different environments. Estimation of path loss is very important in initial deployment of wireless network and cell planning. The authors' main concentration in this paper is to find out a suitable model for sub urban environment to provide guidelines for cell planning of WiMAX at cellular frequency of 3.4 GHz. After successful implementation of wireless broadband communication in small area coverage (Wi-Fi), researchers move forward for the Wireless Metropolitan Area Network (WMAN). To find the solution, in 1998, the IEEE 802.16 working group decided to focus their attention to gaze on new technology.
