Capacity and interference analysis of LTE mobile network using licensed shared access concept

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. This work is focused on the LSA concept and it presents an overview of this Dynamic Spectrum Access (DSA) approach. It is also envisioned a possible case study of the employment of this concept for the Brazilian mining industry development. A simulator of the Long-Term Evolution (LTE) network has been designed, which employs the LSA concept in order to get additional network capacity. Finally, an analysis is performed in terms of secondary users’ capacity and primary users’ interference, as a way to bring trust and attention of the Telecommunications sector with regard to the benefits that this concept can provide.
