Recently, at the “2021 World 5G Conference Series-5G and Carbon Peak, Carbon Neutral Symposium”,Ding Haiyu, director of the Wireless and Terminal Department of China Mobile Research Institute, said that the energy consumption of 5G base stations is about three times that of 4G, and the power consumption is about 1900 watts. It is hoped that through the use of new technologies and new devices, the energy consumption of 5G base stations can be further reduced.

As of the end of March this year, the number of base stations in the 5G network nationwide has reached nearly 820,000, accounting for 70% of the total number of 5G base stations in the world, of which China Mobile accounted for half of 410,000. At present, the number of 5G user connections in my country has exceeded 280 million, accounting for 80% of the global 5G connections, so the development of China’s 5G network is very fast.
The energy-saving and emission reduction of 5G itself has also received much attention. When the construction of 5G just started in 2019, many people said that the energy consumption of 5G base stations reached 4 times that of 4G base stations. But in fact, because 5G itself has a relatively high rate, the energy consumption of a single bit is one-fifth of 4G. However, the amount of bits of a single 5G base station is too large and the rate is high, so the energy consumption of a single station is 4 times that of 4G.
China Mobile will start energy-saving and consumption-reducing work in 2019, such as using new materials to improve the integration of base stations. Today, the energy consumption of a single station has been reduced by 25% compared with 2019. The energy consumption of 5G base stations is now about 3 times that of 4G, and the power consumption is about 1900 watts. It is hoped that through the use of new technologies and new devices, the energy consumption of 5G base stations can be further reduced. China Mobile’s goal is to require the peak power consumption of 5G base stations to be reduced to twice that of 4G during the 14th Five-Year Plan period.
China Mobile, together with industry, academia and research circles, issued a green 5G proposal to fully implement the dual-carbon strategy.
The first is to further strengthen the in-depth integration of 5G and traditional high-energy-consuming industries, including playing a role in product development, technological innovation, and digital transformation with high-energy-consuming industries such as steel, chemical industry, and metallurgy, which can better improve quality and efficiency. Local energy conservation and emission reduction.
The second is to further strengthen the research and development of the upstream and downstream mechanisms of the 5G industry chain. Especially in terms of energy saving and emission reduction, it is hoped that China Mobile’s operators can play a leading role to better integrate with the upstream and downstream industries of corresponding equipment, devices, materials, and corresponding supporting facilities, forming a joint innovation mechanism, and promoting the entire industry chain. Good development.
The third is to strengthen the integration with universities and scientific research institutes. In terms of new materials, new devices, and new energy sources, strengthen basic technology research, strengthen basic research, and better achieve technological breakthroughs, so as to apply to 5G.
The fourth is to build an integrated cooperation platform that integrates research, standards, products, and applications. In the future, an integrated cooperation platform will be formed based on CCSA, and will be combined with universities and scientific research institutions to innovate and carry out a full range of research on the combination of 5G and new energy.
