Fujitsu Limited press release (2024.11.13) (Please note that this announcement is a joint announcement with SoftBank Corp., so there may be some duplication of information.) Fujitsu Limited SoftBank and Fujitsu strengthen partnership towards practical application of AI-RAN SoftBank Corp. (Note 1) (hereinafter referred to as “SoftBank”) and Fujitsu Limited (Note 2) (hereinafter referred to as “Fujitsu”) are developing AI-RAN, a new architecture that integrates AI (artificial intelligence) and RAN (radio access network). We signed a memorandum of understanding on October 25, 2024 to strengthen our partnership toward commercialization of (Note 3) from 2026 onwards. Based on this, the two companies will begin joint research and development of software to maximize RAN performance on AI-RAN and improve the quality of communication experience using AI. Additionally, a validation laboratory will be established at Fujitsu’s base in Dallas, Texas, USA. Furthermore, SoftBank and Fujitsu (hereinafter referred to as the two companies) have been cooperating in the outdoor demonstration experiment of AI-RAN that SoftBank has been conducting since October 2024. Fujitsu is developing vRAN (virtual radio access network) software compatible with L1 software developed based on the NVIDIA AI Aerial platform, which runs on the NVIDIA GH200 Grace Hopper Superchip, and Radio Unit. Both companies have confirmed that it is capable of high quality simultaneous communication of 20 cells per server. The two companies will jointly launch the following initiatives to accelerate the practical application of AI-RAN. 1. Establishment of verification lab to accelerate commercialization of AI-RAN We plan to jointly establish an AI-RAN verification laboratory in Dallas, Texas, where Fujitsu is based, as a place to verify the hardware, software, and applications that make up AI-RAN, and to create new business. This verification lab will conduct technology verification and expand the understanding and ecosystem of AI-RAN. Through this, we will promote the practical application of AI-RAN in the global market. 2. Research and development of vRAN software that promotes “AI for RAN” (Note 4) We will conduct research and development of software that maximizes RAN performance by applying AI. Based on the outdoor demonstration experiment, we will develop and demonstrate software that uses AI to maximize communication performance in real environments, with the aim of further practical application. The two companies will dramatically improve the efficiency of mobile infrastructure investment by using AI to make RAN highly functional and
high-performance and improve communication efficiency. Furthermore, we aim to improve the quality of communication experience for users even when moving or in crowded conditions, and enable new services by performing real-time response and analysis, thereby bringing various innovations to society and industry. Masu. [Comment from Hideyuki Tsukuda, Senior Managing Executive Officer and CTO of SoftBank Corp.] We are pleased that the partnership between our two companies has enabled us to take a step towards the practical application of AI-RAN. In the future, we hope to further improve the efficiency and sophistication of RAN using AI and accelerate the practical application of AI-RAN. [Comment from Shingo Mizuno, Executive Officer, EVP, Deputy Group Manager, System Platform Business Group, Fujitsu Limited] Fujitsu has been working on the technology development of high-performance vRAN software that uses GPUs. By strengthening our partnership with SoftBank, we hope that the technology and practical knowledge of both companies will be more highly integrated, accelerating the creation of new businesses and providing value to more customers and society. .
