Nokia Bell Labs and KDDI Research sign 6G energy efficiency agreement

Nokia Bell Labs and KDDI Research entered a joint research agreement on November 5, 2025, to develop energy-efficient and resilient 6G networks. The collaboration combines KDDI’s real network data and operational insights with Nokia Bell Labs’ energy consumption models and expertise in programmable network architectures. This partnership aims to explore new approaches to enhance network integrity and sustainability.

The initiative seeks to accelerate the commercialization of 6G technology, focusing on critical aspects such as mMIMO energy efficiency and distributed programmable core network services. The companies aim to reduce base station energy consumption while improving communication capabilities, particularly with regard to the proposed 6G spectrum. Additionally, they are developing mobile core technologies designed to maintain communication continuity during infrastructure failures or natural disasters.

KDDI Research and Nokia Bell Labs will showcase their initial findings in mMIMO energy efficiency at the Brooklyn 6G Summit from November 5 to 7. Peter Vetter, President of Core Research at Bell Labs, emphasized that successful collaboration between these leading research institutions can address the inherent networking challenges in this new generation of technology.

Satoshi Konishi, President and CEO of KDDI Research, noted that the focus on collaboration will enhance Research and Development (R&D) initiatives, adding value for customers and contributing to societal progress.
