The Cooling Challenges Of 5G Base Stations

By 2025, the communications industry will consume 20% of the world’s electricity, and in mobile communication networks, base stations are large consumers of electricity, and about 80% of energy consumption comes from widely distributed base stations. More encrypted base stations mean higher energy consumption, which is a major cost challenge facing 5G networks.

From the energy structure, power consumption means higher costs and greater indirect pressure on environmental pollution. From the perspective of thermal design, the base station generates more heat, and the difficulty of temperature control rises sharply. From the measured data in the above figure, the power consumption of 5G base stations has reached 2.5 to 4 times that of 4G base stations.

Engineers who have worked in the communication industry know that communication base stations are usually installed on the iron frame on the roof of the building and high in the field. The size and weight are very important to the installation convenience of the equipment. “Coincidentally” is that power consumption, volume, and weight are the core design boundary conditions in thermal design.
