Cost–Benefit Assessment of 5G Rollout: Insights from Brazil

Abstract

This study provides a comprehensive techno-economic evaluation of the implementation of the 5G network, focusing on the southern region of Brazil. The research examines the capital expenditure (CAPEX) and operational expenditure (OPEX) associated with 5G deployment, assessing the economic viability of various deployment strategies. By analyzing international practices, such as sharing infrastructure, cutting networks, and using neutral networks, this study presents a detailed cost analysis and proposes models to optimize investment. A comparative evaluation of deployment costs between the southern region of Brazil and Belgium underscores the need to adapt European cost models to the Brazilian context. In addition, a case study on rural areas in southern Brazil identifies key challenges and opportunities, highlighting the unique aspects of the implementation of 5G in these regions. This study offers insights into optimizing investments in 5G networks, with the objective of supporting informed decision making for network expansion in diverse geographical and economic contexts.
