Implantação de estação base 5G de baixo custo

Abstract

This work presents the deployment of a 5G network designed for Small and Medium-sized Enterprises (SMEs) using low-cost equipment, including a Raspberry Pi 5 and a self-assembled desktop, along with open-source software serving as the Radio Access Network (RAN) and Core Network (CN). To achieve this, the research addresses the understanding of the architecture of fifth-generation (5G) networks, the licensing requirements for the use of networks and the radiofrequency spectrum in Brazil under the regulation of the National Telecommunications Agency (ANATEL), and an overview of the functionality of software-defined 5G network components. The software solutions were selected based on an analysis of their licensing for commercial use, specifically focusing on srsRAN Project and Open5GS. Two network prototypes are presented: one with the RAN and CN integrated on a Raspberry Pi 5, and another with the RAN and CN decoupled, deployed on the desktop and Raspberry Pi 5, respectively, connected via an Ethernet interface. Despite the limited results, the developed prototypes represent a first step toward refining solutions aimed at serving SMEs using accessible hardware and open-source software.
