On the feasibility of IEEE 802.22 WRAN based broad band for rural Bangladesh: network and coverage planning

This thesis report is submitted in partial fulfillment of the requirements for the degree of Bachelor of Science in Electrical and Electronic Engineering, 2016.Cataloged from PDF version of thesis report.Includes bibliographical references (page 45).Wireless Regional Access Network (WRAN) is progressively turning into the center design for next rural and remote zone access networks throughout all over the world. In the process, WRAN, which saves money on consumption and license costs, has expanded scope range, expanded cell capacity and uses unused or idle television spectrum, was recognized as a reasonable broadband access contender for giving availability of network to the provincial territories of Bangladesh. In the present days, internet has become a vital option for the mass people of Bangladesh. Moreover through this system, it becomes very easy to promote ehealth projects to the people of pastoral area at a very less cost. Besides, people will get the access to internet at low cost. An outline system structure appropriate for rustic regions in Bangladesh is proposed and a fundamental cognitive radio (CR) simulation (based on IEEE802.22 WRAN) to demonstrate the possibility of outfitting unused or idle spectrum of Bangladesh television channels or frequency bands utilizing CR technology was an effective run. Power spectrum density estimation model for sensing was used. Various execution difficulties, for example, the impact of antenna aperture height on the concealed terminal issue are here talked about.Rafi RahmanFarhat Nizam AyonB.
