SoftBank has signed a Memorandum of Understanding (MoU) with Nokia for joint research on developing a communication system that utilises AI, aimed at advancing AI-RAN and 6G technology. Specifically, the partnership will utilise Nokia's virtualised Radio Access Network (Cloud-RAN) platform, with the goal of creating faster, more flexible communication systems. The companies will conduct field tests using centimetre waves, which are expected to be utilised for 6G.

AI-RAN and Centimetre Waves for 6G
AI-RAN (Artificial Intelligence Radio Access Network) technology enables the realisation of next-generation mobile networks by integrating AI and Radio Access Networks (RAN). Centimetre waves are radio waves with wavelengths ranging from 1 cm to 10 cm (equivalently, frequencies ranging from 3 GHz to 30 GHz). SoftBank noted that the frequency range from 7 GHz to 24 GHz, known as FR3 in the 3GPP standard, is expected to be the next new frequency band.
Future of Connectivity
The communication system enabled by AI-RAN and 6G could bring changes to societies and economies by providing faster, more flexible, and broader connectivity, SoftBank explained. This advancement in connectivity could drive progress in smart cities, industrial automation, and new business models.
