Marvell’s 5G Open RAN architecture leverages its OCTEON Fusion processor and underscores collaborations with Arm and Meta to drive adoption of no-compromise 5G Open RAN solutions
The wireless industry’s no-compromise 5G Open RAN platform will be on display at Mobile World Congress 2022. The Marvell-designed solution builds on its extensive compute collaboration with Arm and raises expectations about Open RAN capabilities for ecosystem initiatives like the Meta Connectivity Evenstar program, which is aimed at expanding the global adoption of Open RAN. Last year at MWC, Marvell announced it had joined the Evenstar program [read more]. This year, Marvell’s new 5G Open RAN Accelerator will be on display at the Arm booth at MWC 2022. The OCTEON Fusion processor, which integrates 5G in-line acceleration and Arm Neoverse CPUs, is the foundation for Marvell’s Open RAN DU reference design.
5G is going mainstream with the rapid rollout of next generation networks by every major operator worldwide. The ability of 5G to reliably provide high bandwidth and extremely low latency connectivity is powering applications like metaverse, autonomous driving, industrial IoT, private networks, and many more. 5G is a massive undertaking that is set to transform entire industries and serve the world’s diverse connectivity needs for years to come. But the wireless networks at the center of this revolution are, themselves, undergoing a major transformation – not just in feeds and speeds, but in architecture. More specifically, significant portions of the 5G radio access network (RAN) are moving into the cloud.

Blink your eyes. That’s how fast data will travel from your future 5G-enabled device, over the network to a server and back. Like Formula 1 racing cars needing special tracks for optimal performance, 5G requires agile networking transport infrastructure to unleash its full potential. The 5G radio access network (RAN) requires not only base stations with higher throughputs and soaring speeds but also an advanced transport network, capable of securely delivering fast response times to mobile end points, whatever those might be: phones, cars or IoT devices. Radio site densification and Massive Machine-type Communication (mMTC) technology are rapidly scaling the mobile network to support billions of end devices1, amplifying the key role of network transport to enable instant and reliable connectivity.
With Ethernet being adopted as the most efficient transport technology, carrier routers and switches are tasked to support a variety of use cases over shared infrastructure, driving the growth in Ethernet gear installations. In traditional cellular networks, baseband and radio resources were co-located and dedicated at each cell site. This created significant challenges to support growth and shifts in traffic patterns with available capacity. With the emergence of more flexible centralized architectures such as C-RAN, baseband processing resources are pooled in base station hubs called central units (CUs) and distributed units (DUs) and dynamically shared with remote radio units (RUs). This creates even larger concentrations of traffic to be moved to and from these hubs over the network transport.
