Abstract

TV White Spaces (TVWS) are becoming more and more attractive for deploying high-speed broadband wireless communications in the freed spectrum left from the analog switchoff (ASO). In this respect, dynamic spectrum access (DSA) procedures are critical and have to rely on very accurate spectrum sensing techniques. This paper provides an overview of the current state of the art in dynamic spectrum access in TV white spaces and presents results of measurement campaigns for identifying TV white spaces in the city of Bucharest, before the ASO in Romania.
