Abstract
The spectrum “scarcity” problem can be tackled by promoting a more efficient use of this resource. Spectrum sharing techniques, e.g. TV White Spaces (TVWS) and Licensed Shared Access (LSA), are good solutions for this problem and there are already regulation and standardization efforts worldwide. The Brazilian regulatory scenario is not that advanced regarding spectrum sharing, but there are already some actions towards the adoption of this concept for the Brazilian reality. This paper gives an overview of the spectrum sharing concept and the Brazilian telecommunications regulatory scenario. Case studies regarding the employment of both TVWS and LSA in the Brazilian scenario are also presented as a way to bring more attention to the adoption of those concepts in the country.
