Cognitive Radio and TV White Space Communications: TV White Space Geo-location Database System
MetadataShow full item record
The aim of this thesis is to research in the use of emerging TV white space communications, implementing a geo-location database system. For that, some research and theoretical studies related to cognitive radio and TV white space communications will be done first, focusing on current activities, standarization processes, commercial approaches and related projects. Once the background and the present TV white space communications status is analyzed, a geolocation database system will be designed and developed to prove the potential of this technology. The operation of the database system will be demonstrated through a web interface. In this way, an open and publicly accessible geo-location database system implementation and structure will be created (note that even if several database system creation initiatives are taking place, most of them are private). However, due to the lack of official regulatories, established standards, and actual transmission data (data from TV broadcasters, wireless microphones etc.), only an initial TV white space database system demo will be implemented to model the operation of the same. It will be possible to access and query this database systemthrough a simple web interface for the Oslo area. After analyzing the results of the implementation and looking to other TV white space initiatives, some considerations for future work will be concluded.
