ENERGY EFFICIENCY IN 5G NETWORKS A CURRENT OVERVIEW
Conteúdo do artigo principal
Resumo
The increasing expansion of mobile data traffic has intensified the demand for more efficient and sustainable network solutions. Fifth-generation (5G) mobile networks have introduced unprecedented advancements in speed, capacity, and connectivity; however, they also present significant energy consumption challenges. As energy costs and environmental concerns grow, improving the energy efficiency of 5G systems has become essential. Energy efficiency is now recognized as a critical Key Performance Indicator (KPI) for the design, deployment, and operation of 5G networks. This article provides an up-to-date overview of strategies and emerging technologies aimed at enhancing energy efficiency in 5G infrastructures. Focusing on innovations such as Massive MIMO, sleep mode techniques, Reconfigurable Intelligent Surfaces (RIS), and AI-driven energy management, highlighting how the telecommunications industry is adapting to the imperative of greener, more sustainable networks.
