Arm Joins O-RAN Alliance to Promote Open Development of 5G Network Architecture

Arm has always been a leader in driving all generations of cellular network technology, and with more than 25 years of collaboration with ecosystem partners, Arm is now the CPU architecture of choice for infrastructure deployments around the world. 5G technology holds great promise for building a world that breaks through traditional human-to-human connections. Thanks to higher performance, higher bandwidth, lower latency, and more connections, 5G opens up new possibilities for immersive experiences, smart cities, industrial IoT, autonomous driving, and many more unimaginable areas. door to multiple applications. Arm, backed by a vast ecosystem, will play a central role in enabling this critical shift.

As more operators around the world deploy 5G (111 operators have deployed 7,220 projects as of Q1 2020), the industry is making a concerted effort to drive innovation at the new radio technology and network level, as well as deployment and supply chain change. Telecom Operators (MNOs) mostly rely on traditional network OEMs to build, deploy and maintain architectures to tune their networks to meet user needs. However, the following new trends also provide telecom operators with different vendor choices:

  • Cloud-native: The rapid rise of containers and virtualization, coupled with the extremely fast-paced rollout of DevOps software, requires the use of a common cloud-native development environment that covers edge-to-cloud deployment options.

  • Openness: Open systems and open standards foster innovation, bring needed services to market faster, and benefit the entire ecosystem of end users, telecom operators, and vendors. The decoupling of network architecture (RAN) is mainly promoted by telecom operators, because open interfaces defined by industry organizations such as the O-RAN Alliance are gradually being welcomed by telecom operators and manufacturers.

  • Interoperability: Use the RAN white box test of the general computing platform, and obtain the assistance of software manufacturers, original design manufacturers (ODMs) and system integrators for hardware acceleration.

Every day, more than 70% of the world’s people use Arm’s technology. Arm’s ecosystem has rich solution options to meet energy consumption, performance and scalability needs. Therefore, from terminal devices to the cloud, Arm plays an important role in realizing 5G. character of. The Arm Neoverse CPU launched for the infrastructure market has a performance/energy ratio improvement of more than 40% compared to competing products, which can help telecom operators reduce operating expenses over the life of their equipment.

Widespread deployment of 5G requires more than a best-in-class processor. Arm works closely with a broad ecosystem of developers and has contributed significantly to more than 100 open source proposals, including operating systems, continuous integration and release (CI/CD), virtual machines, containers, and An end-to-end security and networking software stack. Arm is now a key member of many telecom-focused organizations, including the Telecom Infra Project, DPDK,, and the Linux Foundation’s Akraino Project.

The O-RAN Alliance is a leading industry forum where experts in various fields drive the vision of openness and innovation. Arm is excited to join the O-RAN Alliance to accelerate the realization of this vision. Participating in O-RAN enables Arm to accelerate its focus on telcos and vendors as they deploy open, interoperable and cloud-native 5G technologies. Arm will provide the telecom industry community with a wide range of development tools and ecosystem resources, as well as high-performance and power-saving computing solutions, thereby enabling the 5G architecture. Arm and its partners help the industry meet a wide range of computing needs, from the rollout of network architectures to the processors within each device, covering all key areas of 5G. Arm looks forward to taking the next important step in the development of 5G!
