Analysis of Wimax Connectivity in Rural and Urban Area Using Okumura-Hata Propagation Model

Abstract

Worldwide Interoperability of Microwave Access (WiMAX) technology becomes popular and receives growing acceptance as a Broadband Wireless Access (BWA) system. It is capable of delivering broadband Internet service and extending services like Internet telephony throughout India without major disruption to transportation and other services. Predicting path loss and finding coverage area are important factors in wimax wireless system for proper planning, interference estimations and frequency assignments. We use the Okumura –Hata model for computing a transmission coverage area and propagation loss in any outdoor environment such as rural, urban, and suburban. The system was developed by using Matlab software in that on rural or urban map image, we place the transmitter point on the map and inputs such as Frequency ,Transmitter Power ,Gain, Height ,System Loss ,Distance are for a that particular image  and compute coverage area and propagation loss. A coverage area and propagation loss for different area is observed. By varying frequency and distance we compare a coverage area and propagation path loss for different geographical areas.
