The power consumption of a single 5G station is 2.5 to 3.5 times higher than that of a single 4G station. The main factor behind this increase in 5G power consumption is the high power usage of the active antenna unit (AAU). Under a full workload, a single station uses nearly 3700W.
Selected 5G base stations in China are being powered off every day from 21:00 to next day 9:00 to reduce energy consumption and lower electricity bills. 5G base stations are truly large consumers of energy such that electricity bills have become one of the biggest costs for 5G network operators.
It also provides a way to solve the problem of 5G energy consumption. This paper puts forward a scheme to install photovoltaic energy storage system for 5G base station to reduce the power supply cost of the base station, compares it with the energy consumption cost of 5G base station in different situations, and analyzes the economy of the scheme.
Although the absolute value of the power consumption of 5G base stations is increasing, their energy efficiency ratio is much lower than that of 4G stations. In other words, with the same power consumption, the network capacity of 5G will be as dozens of times larger than 4G, so the power consumption per bit is sharply reduced.
A 5G base station is mainly composed of the baseband unit (BBU) and the AAU — in 4G terms, the AAU is the remote radio unit (RRU) plus antenna. The role of the BBU is to handle baseband digital signal processing, while the AAU converts the baseband digital signal into an analog signal, and then modulates it into a high-frequency radio signal.
The current 200,000 base stations can save 1.2 billion annually. By the end of this year, 1 million 5G base stations will be built, saving 6 billion in a year. If there are more than 2 million base stations, 12 billion electricity can be saved a year, which is equivalent to China Unicom’s total profit in one year.
