Emerging wireless technologies based on shared spectrum networks which effectively utilize available TV white space spectrum in conjunction with cognitive radio (CR) are being tested in South Africa and several other countries. It is expected that shared spectrum wireless broadband networks (SS-WBN) will play an increasing role in the provisioning of access to universal broadband internet and associated services, with lower cost/bandwidth figure in rural areas and the next billion users in emerging economies. In the shorter term, wireless links can also serve as backbone links to facilitate access for those of the next billion customers that live in areas of lower priority in the deployment programmes for optical fiber. In this paper an intelligent design of a TV white space spectrum database (TVWS-SDB) to enable reliable shared spectrum wireless broadband networks with low interference to primary licensed users (PLU) will be described.
Dr. Fisseha Mekuria, has acquired Tekn.Lic & PhD. degrees from Linköping University (LiTH.se) in Sweden. He has over 20 years of academic and industrial research experience, in ICT & wireless communications. He was a senior researcher at Ericsson Mobile Communications R&D Lab in Sweden for 10 years. During this time he has developed over 12 US & European (EPO) patents in the areas of wireless computing platforms & communications Networks. Dr. Mekuria has also played a crucial role in commercialization of research outputs as mentor in the IDEON research Park in Sweden, and has been a recipient of several research grants & IEEE nominations from the mobile & ICT industry for research and academic education in the mobile computing field. As Professor in Wireless Computing & ICT Systems, at several Universities, he has been involved in the development of curriculums, teaching and organization of research groups. He is accustomed to taking leadership roles in research and educational capacity building in Europe and several African countries. He has also been involved in creating mobile applications software development labs and wireless networking laboratories in resource-limited African countries. For this work he has been nominated for the prestigious IEEE continuing education award. Several Patents, IEEE/ACM publications & book chapters in wireless communications has been the result of his work. He is the recipient of the Google Research Award 2009/10 in Mobile Computing, and an US-NSF research grant recipient in Collaboration with the University of California, Santa Barbara. His research interests are next generation wireless computing and green network technology systems, modelling and analysis of secure opportunistic wireless platforms & services. He has worked in mobile broadband networks for health and education applications and ICT for sustainable socio-economic development. He is at present the principal researcher and research leader in wireless computing and networking, at the Council for Scientific and Industrial Research, CSIR Meraka advanced ICT institute, in Pretoria, South Africa. He also holds an Adj. Professor position at the University of Johannesburg, Faculty of electrical and electronics engineering science, South Africa.
