Abstract

Mobile network data rates are increasing with each generation, due to the usage of emerging technologies and advanced architectures. They may consume substantially more power than the present fourth-generation (4G) and fifth-generation (5G) systems. Base stations have been determined as the primary source of energy usage in a mobile network. They are responsible for more than 60% of the energy consumption of mobile networks. Moreover, the recent 5G base stations (BSs), which provide higher bandwidth and data rates and have more transceivers with centralized antennas, raise alarms about their power consumption. With eco-friendly concerns about the amount of carbon dioxide (CO₂) reduction, the intergovernmental panel on climate change (IPCC) sees climate change as a threat to human well-being and planetary health, and ever-increasing energy costs have already created an urgent need for more energy-efficient and low-power consumption BSs in mobile communications. As a result, the energy consumption and carbon emissions of 5G mobile networks are concerning. Information and communication technologies (ICT) have great potential for reducing CO₂ emissions. Therefore, power consumption is one of the central topics for telecom network providers, especially when they are challenged by higher costs. Distributed antenna systems (DAS) could decrease network power usage through smaller cell size or moving closer to users. In this study, we look at the impact of cell size on power consumption in centralized and distributed antenna systems. The distributed antenna system consumes more than 35% less power than the usual centralized structure; thus, swapping a centralized antenna with a distributed antenna may lower total power consumption.
