Nokia, NTT DOCOMO, INC. and NTT have achieved two key technological milestones in the development of 6G networks. These include the implementation of Artificial Intelligence (AI) and Machine Learning (ML) into the radio air interface, as well as the utilization of new sub-terahertz (sub-THz) spectrum to boost network capacity. The companies have implemented both technologies as proofs of concept at Nokia Bell Labs in Stuttgart, Germany and will be demonstrating them at Mobile World Congress in Barcelona. These advancements could pave the way for new immersive metaverse and extended reality (XR) experiences and a new generation of mobile applications.
