NTT Docomo has announced an Open RAN service lineup comprising OREX RAN, OREX SMO and OREX Services for international telecom operators.
Developed in collaboration with multiple global vendors, OREX can be customised to address each customer’s unique challenges. OREX Open RAN services is expected to reduce clients’ total cost of ownership by up to 30 percent when the costs of initial setup and ongoing maintenance are taken into account. It can also halve the time needed for network design. Additionally, OREX slashes power consumption at base stations by up to 50 percent.
Driving these new services is a GPU-accelerated wireless solution, making the Japanese telco the world’s first telco to deploy a GPU-accelerated commercial 5G network.
The 5G Open RAN solution uses a high-performance 5G virtual radio access network (vRAN) from Fujitsu built on the NVIDIA Aerial vRAN stack and NVIDIA Converged Accelerators. This combination enables telcos to create a fully software- and cloud-defined network that can dynamically allocate resources using industry-standard equipment.
“Open RAN offers the opportunity to build next-generation 5G networks with unprecedented flexibility and scalability thanks to multivendor connections. We look forward to continuing working with NVIDIA on infrastructure solutions that meet those needs,” said Sadayuki Abeta, Global Head of Open RAN solutions at NTT Docomo.
The 5G Open RAN solution is the first 5G vRAN for telco commercial deployment using the NVIDIA Aerial platform, with a hardened, carrier-grade vRAN stack. The platform brings together the NVIDIA Aerial vRAN stack for 5G, AI frameworks, accelerated compute infrastructure and long-term software support and maintenance.
Working with offerings from Fujitsu and Wind River, the new 5G solution uses the NVIDIA Aerial platform to lower costs and reduce power consumption.
“Delivering a 5G Open RAN network that meets stringent performance requirements of operators is a significant accomplishment. 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,” said Masaki Taniguchi, Senior Vice President and Head of the Mobile System Business Unit at Fujitsu.
