AI control reduces base station power consumption by up to 50%

KDDI CORPORATION

Outline

KDDI CORPORATION and Nokia Solutions & Networks Japan G.K. have agreed to conduct a demonstration test (hereinafter referred to as this demonstration test) aiming to reduce CO₂ emissions by reducing the power consumption of mobile phone base stations. In this demonstration test, Nokia's base station AI control technology and base station liquid cooling technology will be introduced to commercial mobile phone base stations for the first time in Japan.

Base station AI control technology analyzes changes in traffic volume for each base station and dynamically stops and emits radio waves to reduce power consumption by up to 50%. Base station liquid cooling technology accommodates base station equipment. We aim to reduce the power consumption of the air conditioning in the room by 70% or more.

Description

1. Base station AI control technology (Nokia AVA Energy Efficiency)

By combining the know-how of telecommunications carriers with the radio wave control of base stations by AI, we will reduce the consumption of power used by base stations while maintaining the quality of experience of our customers. AI analyzes changes in traffic volume due to seasonal fluctuations for each base station, determines the appropriate time zone and traffic volume, and dynamically stops and emits radio waves. As a result of joint verification with Nokia in the KDDI verification environment, it has been confirmed that it is possible to reduce power consumption by up to 20% on average in an environment with low traffic volume and by up to 50% depending on the time of day for each base station.

In addition, it can be installed regardless of the base station development vendor or communication method, and it can be installed in many KDDI base stations in the future.

2. Base Station Liquid Cooling Technology (Nokia Liquid Cooling AirScale Baseband Solution)

We have introduced a base station liquid cooling function that cools with a liquid refrigerant that has higher cooling efficiency than the conventional air cooling method, and reduces the amount of air conditioning power used to cool the room where the base station equipment is housed. Estimates that take into account the amount of heat generated by base station equipment and the performance figures of air conditioning equipment are expected to reduce power consumption by 70% or more.

In addition, the liquid cooling system is basically maintenance-free and silent, so it can be easily deployed in various locations.
