Nostalgia! Do you remember the days when there was an era of 2G and 3G? But as we say, time is precious and never waits for anyone. It just goes away. Yes, this saying is correct; now we are living in the 4G era, and 5G is on the way. Recently, the Japanese telecom giant NTT DOCOMO laid the first stone at MWC Las Vegas by deploying the first 5G network to use graphics processing unit-accelerated wireless technology in a commercial setting.
Keeping the advanced era in mind, global telecommunications companies are exploring how to cost-effectively deliver many of these new AI applications to the ill-at-ease 5G and upcoming 6G networks. NTT DOCOMO disclosed that it is deploying a GPU-accelerated wireless solution in its network, obviously in Japan.
On the other hand, by 2025, Telcos are also planning to bring into service over 17 million 5G microcells and towers worldwide. It decides how to build, manage, and optimize this new infrastructure while taking care of quality-of-service delivery and gathering more and more customer experience, which is the next big challenge of the industry.
The reason behind this move of DOCOMO is just to unlock the flexibility, scalability, and supply chain diversity promise of Open RAN and concentrate the multibillion-dollar problem and bugs of driving improvements in performance. The 5G Open RAN solution uses a high-performance 5G virtual radio access network from Fujitsu built on the NVIDIA Aerial vRAN stack and NVIDIA Converged Accelerators, and the fact is this combination will empower telcos to develop a full software and cloud-defined network that can dynamically allocate resources with the help of industry-standard equipment.
The global head of Open RAN solutions at NTT DOCOMO stated that; “Open RAN offers the opportunity to build next-generation 5G networks with unprecedented flexibility and scalability thanks to multivendor connections.”
Cost & Energy-Efficiency Benefits Of GPU Acceleration
Along With the Fujitsu and Wind River, the latest 5G solution uses the NVIDIA Aerial platform for cheaper costs and less power consumption. As compared to its existing 5G network deployments, DOCOMO discloses that the solution reduces total costs by up to 30%, whereas network design utilization by up to 50% and power consumption by 50%.
It is also disclosed that; “Using our Fujitsu vCU/vDU, in combination with NVIDIA Aerial platform, will help network operators to efficiently build high-performance 5G networks for consumers and businesses alike.”
Fujitsu, NVIDIA, and Wind River have been working below the OREX (which is a 5G Open RAN service brand) that DOCOMO debuted in February 2021 to develop the Open RAN 5G vRAN. OREX has been established in Japan based on Fujitsu’s virtualized DU (vDU) and virtualized CU (vCU), which also weight commercial off-the-shelf servers, whereas the Wind River cloud platform, Fujitsu’s 5G vRAN software and NVIDIA Aerial vRAN stack & NVIDIA Converged Accelerators.
OREX: Building Out From Japan & Beyond
DOCOMO and its partners in OREX are encouraging a multivendor, Open RAN-compliant 5G vRAN to the global operator community. Commercial categorization in Japan is a first step in the vision of OREX, where members can commercially confirm their solutions and, after that, promote them to other operators globally.
The summary is that NVIDIA is shaking hands with DOCOMO and other partners just to support operators around the world to deploy high-performance, energy-efficient, software-defined, commercial 5G vRAN.
