Revolutionizing Telecom: NTT DOCOMO Launches First GPU-Accelerated 5G Network in Commercial Use

Japan has recently deployed an advanced 5G network thanks to the collaborative efforts under the 5G Open RAN Ecosystem Experience (OREX) service brand. This collaborative project brings together 13 tech companies, including industry leaders such as Nvidia Corp., Fujitsu Global, and Wind River Systems Inc., to revolutionize the telecom industry.

Open RAN refers to an open and interoperable approach to Radio Access Network (RAN) architecture for mobile networks. It aims to enhance flexibility, innovation, and competition in the telecommunications industry. By adopting Open RAN, wireless carriers can decouple hardware and software components, allowing for the integration of equipment from different vendors. This promotes interoperability, offers more choices, and encourages the adoption of advanced technologies, ultimately leading to greater network efficiency, cost-effectiveness, and improved user experience. Open RAN, or Open Radio Access Network, is a concept that allows multiple vendors to interoperate, breaking the hold of traditional single-vendor setups. This approach brings flexibility, innovation, and cost-effectiveness to the development and deployment of 5G networks.

Description of the newly implemented network in Japan

The newly implemented network in Japan incorporates a high-performance 5G virtual RAN (vRAN) developed by Fujitsu and built on Nvidia’s Aerial 5G vRAN stack and converged accelerators. This collaboration leverages the expertise of both companies to create a powerful and efficient network infrastructure.

Integration of artificial intelligence and machine learning

The integration of artificial intelligence (AI) and machine learning (ML) in the network enables automatic network slicing, enhancing service quality, resource control, and user experience. AI and ML algorithms analyze network conditions in real-time and dynamically allocate resources to ensure optimal performance.

Benefits of adding accelerators like GPUs to wireless networks

Adding accelerators like GPUs (Graphics Processing Units) to wireless networks brings significant benefits. It reduces total costs by up to 30% and enhances network design utilization by 50%. The additional processing power provided by GPUs allows for more efficient data processing, resulting in a higher-performing network.

Overview of Nvidia’s Aerial Platform

Nvidia’s Aerial platform is designed specifically for software-defined, GPU-accelerated, cloud-native 5G networks. It provides a robust and flexible infrastructure that enables network operators to leverage the power of GPUs and cloud-native technologies, revolutionizing the way 5G networks are built and managed.

The role of Wind River Systems

Wind River Systems plays a crucial role in the project by providing a cloud platform for deploying the OREX 5G vRAN. This cloud platform is based on open-source technology, allowing operators to deploy and manage their 5G networks globally. Wind River Systems’ contribution ensures scalability, interoperability, and ease of management for the network operators.

Importance of the deployment in Japan

The deployment of the advanced 5G network in Japan marks a pivotal first step in demonstrating the commercial viability of these key technologies. By showcasing the successful collaboration of multiple vendors and the tangible benefits of Open RAN, this project paves the way for the widespread adoption of these transformative technologies in the telecom industry.

Introduction to NTT DOCOMO’s OREX brand offerings

NTT DOCOMO, one of Japan’s leading mobile network operators, bundles these cutting-edge technologies under the OREX brand. They offer three packages for network operators: OREX RAN, which focuses on the virtualization and openness of the radio access network; OREX SMO, which offers service orchestration capabilities; and OREX Services, which provides a range of services to enhance network performance and user experience.

Simplified Vendor Integration through OREX

One of the key advantages of utilizing the OREX brand is the simplified vendor integration process. Network operators can select vendors without worrying about integration complexities, as NTT DOCOMO and its partners ensure seamless integration and compatibility. This allows operators to focus on choosing the best technology and solutions without being limited by vendor lock-in.

The collaborative effort under the 5G Open RAN Ecosystem Experience has enabled the implementation of an advanced 5G network in Japan. The combination of Fujitsu’s high-performance vRAN, Nvidia’s Aerial 5G vRAN stack, and Wind River Systems’ cloud platform has resulted in a powerful, flexible, and efficient network infrastructure. With the added integration of AI, ML, and GPU accelerators, this network sets a new standard for performance, cost-effectiveness, and user experience. NTT DOCOMO’s OREX brand provides a comprehensive suite of solutions for network operators, simplifying the deployment and management of advanced 5G networks. This deployment in Japan serves as a significant milestone in showcasing the commercial viability of Open RAN and paves the way for a future where innovative technologies reshape the global telecom industry.
