Towards an IEEE 802.22 (WRAN) based wireless broadband for rural Bangladesh- point-to-point link, coverage, and CPE antenna design

In accordance with the global awareness and national agenda of providing digital services to the rural population of Bangladesh to improve their quality of lives, broadband internet connectivity to the remote corners of the country has been a major infrastructural concern. The purpose of this paper is to evaluate the potential of IEEE802.22 Wireless Regional Area Network (WRAN) to serve this purpose. The initial hypothesis was that due to the flat nature of terrain in most areas of the country, it would be economic to deploy WRAN infrastructure in the unused TV white spaces covering large flat areas. However, establishing Point-to-point links might be challenging due to the same reason. To come to a concrete conclusion about the technical feasibility of this technology and an infrastructural estimate, we started this project from scratch, i.e. designing necessary antennas, up to evaluating their coverage and P2P performance in a computer simulation tool. The contribution of this thesis is to theoretically design the necessary antennas and Customer Premises Equipment (CPE) needed for such a deployment.
