Nokia and Rohde & Schwarz develop AI 6G receiver technology

Nokia and Rohde & Schwarz partnered to create a 6G radio receiver that utilizes Artificial Intelligence (AI) technologies to address coverage issues expected with higher-frequency 6G spectrum. The receiver aims to enhance uplink distance, improving coverage and potentially reducing deployment costs for operators.

The companies tested the technology and reported uplink distance enhancements ranging from 10% to 25% compared to current receivers. This capability allows operators to implement 6G technology over their existing 5G infrastructure, facilitating a more efficient rollout.

Nokia Bell Labs developed the AI-powered receiver. The collaboration's proof-of-concept will be presented at the Brooklyn 6G Summit on November 6, 2025. The receiver evaluates wireless signal distortion, which contributes to the improved coverage. Machine Learning (ML) capabilities in the device help in overcoming some of the known limitations associated with 6G networks.

Peter Vetter, President of Core Research at Nokia Bell Labs, indicated the significance of reducing the need for additional cell sites traditionally required to enhance coverage in denser networks. Rohde & Schwarz utilized advanced test equipment to validate the receiver's performance under real-world conditions.

Michael Fischlein, VP at Rohde & Schwarz, expressed confidence in their partnership with Nokia and emphasized their ability to support next-generation wireless technology development. The collaboration aligns with both companies' history in technological advancements and their commitment to the future of 6G.
