The explosive growth of mobile data traffic has resulted in a significant increase in the energy consumption of 5G base stations (BSs).
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, , .
“5G is here, and while the expansion of this connectivity continues and the benefits of an energy conscious, future-proof portfolio are evident, it's simply not enough on its own just to dramatically reduce energy consumption for entire mobile networks. We cannot continue with a 'business as usual' approach.”
Emerging use cases and devices demand higher capacity from today's mobile networks, leading to increasingly dense network deployments. In this post, we explore the energy saving features of 5G New Radio and how this enables operators to build denser networks, meet performance demands and maintain low 5G energy consumption.
Energy efficiency assumes it is of paramount importance for both User Equipment (UE) to achieve battery prologue and base stations to achieve savings in power and operation cost.
