How does mobile data traffic affect the energy consumption of 5G base stations?

The explosive growth of mobile data traffic has resulted in a significant increase in the energy consumption of 5G base stations (BSs).

What is 5G BS power consumption?

The 5G BS power consumption mainly comes from the active antenna unit (AAU) and the base band unit (BBU), which respectively constitute BS dynamic and static power consumption. The AAU power consumption changes positively with the fluctuation of communication traffic, while the BBU power consumption remains basically unchanged , , .

What is 5G base station?

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 .

What is a minimal 5G BS energy consumption optimization model?

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).

Is HCN a good 5G network?

Generally, the HCN that only include MBSs or SBSs are common network in the communication field. HCN, as one of the main 5G technologies, can improve system capacity, coverage and energy efficiency. Therefore, the HCN is selected for numerical simulation to verify the effectiveness of the strategy proposed in this paper.

Why is low band LTE so important?

Because of that it has a much smaller generator and to prolong the time before it runs out of fuel (roads could be impassable during an extended winter outage) only low band LTE stays on. It draws the least amount of power yet still allows people to call relatives, 911, etc.
