An Analysis of Licensed Shared Access Use in Brazil - Advantages and Challenges

The increase in mobile network traffic is leading to a spectrum scarcity challenge. Spectrum sharing techniques, such as Licensed Shared Access (LSA), are an effective solution to enhance spectrum utilization and, as a result, support the growing volume of mobile network traffic. This paper provides an overview of the LSA technique and its regulation around the world. An analysis of the technique's implementation in Brazil is also presented, outlining the benefits for the National Telecommunications Agency (Anatel), current spectrum incumbents, and future LSA licensees. Furthermore, the 900 MHz, 2.3 GHz, 3.7 GHz, and 26 GHz bands have been proposed as promising candidates for the implementation of the LSA technique in Brazil.
