Get a quoteBy 2025, the worldwide 5G base station number is anticipated to be 65 million. Table 1 shows the power consumption of typical 4G and 5G macro base stations at 2.6 GHz, as measured by China Mobile in 2019. The total power of a base station includes the power consumption for baseband processing and the power of the remote radio unit (RRU).
A 4G base station has a transmission power of 40 W for a bandwidth of 20 MHz for each sector (there are typically three sectors) and uses eight transmission and eight reception antennas. In contrast, a 5G base station has a transmission power of 240 W for a bandwidth of 100 MHz and uses 64 transmission and 64 reception antennas.
1. Introduction 5G base station (BS), as an important electrical load, has been growing rapidly in the number and density to cope with the exponential growth of mobile data traffic . It is predicted that by 2025, there will be about 13.1 million BSs in the world, and the BS energy consumption will reach 200 billion kWh .
Higher base station density. The average density of 5G base stations is expected to be three times higher than that of 4G. By 2025, the worldwide 5G base station number is anticipated to be 65 million. Table 1 shows the power consumption of typical 4G and 5G macro base stations at 2.6 GHz, as measured by China Mobile in 2019.
The data here all comes from operators on the front lines, and we can draw the following valuable conclusions: 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).
Therefore, the problem can be formulated as a minimal 5G BS energy consumption optimization model, i.e., the energy consumption reduced by reasonably switching off the idle or lightly loaded BSs and reasonably associate UEs with BSs (i.e., the BS switching state and BS-UE association state scheme).
