RAN Power Savings
Fujitsu implements a three-stage approach to RAN power savings:
- Efficient Radio Units: Utilize innovative power amplifier architecture for high power energy efficiency and support advanced dynamic power savings schemes that scale with traffic.
- Intelligent SMO/RIC AI Driven rApp: Features Artificial Intelligence applications that identify and turn off unnecessary cells while preserving user experience.
- Optimized Virtual CU/DU: Incorporates new CPU and accelerator options to reduce power consumption by up to 30%, and utilizes Cell Resource Sharing to double the number of cells connected in low-capacity sites, thereby reducing the number of servers.
This approach leads to power saving performance and reduced CO2 emissions.
