Optical Technologies for 5G Access Networks

By Matt Bolig, Director, Product Marketing, Networking Interconnect, Marvell

There’s been a lot written about 5G wireless networks in recent years.  It’s easy to see why; 5G technology supports game-changing applications like autonomous driving and smart city infrastructure.  Infrastructure investment in bringing this new reality to fruition will take many years and 100’s of billions of dollars globally, as figure 1 below illustrates.

When considering where capital is invested in 5G, one underappreciated aspect is just how much wired infrastructure is required to move massive amounts of data through these wireless networks.

Unleashing 5G Network Performance with Next Generation Ethernet

By Alik Fishman, Director of Product Management, Marvell

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.

Marvell Enables O-RAN to Help 5G Fulfill its True Potential

By Marvell, PR Team

At the most recent FierceWireless 5G Blitz Week, some of the world’s leading 5G innovators met via webinar to discuss the potential of O-RAN and challenges of the ongoing 5G rollout. In a keynote, EVP and General Manager of Marvell’s Processors Business Group Raj Singh explored the accelerating shift to O-RAN, which is an emerging open-source architecture for Radio Access Networks that enables customers to create better 5G applications by mixing and matching RAN technology from different vendors.

O-RAN architectures are compelling because they increase competition among vendors, reduce costs, and offer customers greater flexibility to combine RAN elements according to their application’s specific use cases. However, in addition to their obvious benefits, O-RAN solutions also raise operator concerns including potential challenges with integration, legacy support, interoperability and security – issues that Marvell and other companies in the Open RAN Policy Coalition are addressing through shared standards, proven solutions and innovative approaches.
