Perspective of the use of TV White Space in Brazil

Abstract

The demand for new communications services increases the need for new bands in the radio spectrum. Currently, broadband services have allowed the majority of the population to continue their work and study activities in home office. Nevertheless, this is not the reality of regions further away from large urban centers. Through measurements in the Digital TV UHF band, a waste of bandwidth has been observed, that is, the so-called TV White Spaces, which could be used by new broadband access services. This article presents a study on the advancement of TV White Spaces use in the world and a preliminary assessment through a measurement campaign to validate the use of this approach.
