Over the past few years, there has been an increasingly steady drumbeat for the need to diversify and open the telecommunications supply chain. This has been driven both by security concerns and by the need to improve the negotiating power of operators by introducing new entrants into the market. A key part of this supply chain that can be diversified is radio access network (RAN), where operators <\/a>have typically spent most of their investments in network infrastructure.<\/p>\n\n\n\n

To address the need for diversification, groups such as the O-RAN alliance<\/a> have formed to open up RAN capabilities. In addition, select operator communities from all over Europe<\/a>, the Middle East<\/a>, Asia<\/a>, and Africa<\/a> have begun experimenting in this space. Governments have also been weighing in, designating telecommunications networks as a national priority and a critical part of infrastructure that needs to be secured, and nurtured to drive innovation. An example of this was the UK Government’s 5G diversification strategy<\/a>\u2014a plan to grow the telecommunications supply chain while simultaneously making it more resilient to future trends and threats.<\/p>\n\n\n\n

Microsoft has successfully transformed into an edge and cloud company; so, we understand the magnitude of such an evolution. At Microsoft, our guiding principle is to support, develop, and foster a partner-rich ecosystem<\/a>. We believe that the role that we play best as a cloud provider is to provide a secure, scalable, well-managed carrier-grade platform serving as the enabler for third parties to build upon.<\/p>\n\n\n\n

Future Radio Access Network Challenge (FRANC)<\/h2>\n\n\n\n

As it turns out, the UK government’s Department of Digital, Culture, Media, and Sports (DCMS)<\/a> was thinking along the same lines. The Future Radio Access Network Challenge (FRANC)<\/a> was designed as a follow-on to their diversification strategy. It identified the need to accelerate Open RAN innovation to meet its target of 35 percent of all network traffic over Open RAN by 2030<\/a>, as well as spark UK-based innovation in this space.<\/p>\n\n\n\n

This initiative aligns well with our ambitions\u2014to grow and diversify the supply chain as well as support a healthy and vibrant Open RAN ecosystem. We reached out to Intel and Capgemini, industry leaders in Open RAN, and the University of Edinburgh, a leading academic institution, to join us in demonstrating how beautifully our ideas could fit together to achieve our mutual objectives.<\/p>\n\n\n\n

DCMS has endorsed this approach, with the Microsoft-led consortium being one of the award recipients<\/a> of their challenge. At the Mobile World Congress (MWC) 2022, we pulled back the curtain a bit more to explain what we will be doing jointly as a group<\/a>, and how our combined efforts will help accelerate the Open RAN ecosystem.<\/p>\n\n\n\n

Technology showcased at the Mobile World Congress 2022<\/h2>\n\n\n\n

At MWC 2022, in close collaboration with our partners, we showed how disaggregated software and hardware are the future of telecommunications networks. This new software-driven programmable network architecture leads to faster rollouts with lower total cost of ownership. Cloud technologies\u00e2\u20ac\u201dAI and machine learning analytics, edge computing, large-scale management, self-diagnostics, network programmability, network verification, and global connectivity\u00e2\u20ac\u201dcan be leveraged to improve highly secure operational efficiency of the virtualized RAN. This infrastructure also supports the creation of new revenue streams through the enablement of a developer ecosystem.<\/p>\n\n\n\n

Additionally, we announced the next wave of Azure for Operators solutions and services<\/a>, which includes Azure Operator Distributed Services (AODS). AODS combines the enhanced version of AT&T’s Network Cloud<\/a> software we acquired with the best of Azure, including our industry-leading security, monitoring, analytics, AI, machine learning, and so much more. Capable of handling network-intensive workloads and mission-critical applications, AODS is a carrier-grade platform that provides flexibility and scalability to support deployments at the edge of the cloud, the edge of the network, or the enterprise edge. We\u00e2\u20ac\u2122ve been focused on ensuring that this edge infrastructure (both near and far edge) is capable of supporting RAN workloads<\/a>.<\/p>\n\n\n\n

We demonstrated a system that used our AODS solution, which provides hybrid cloud platform for telecommunications network functions. The architectural components included commercial off-the-shelf hardware equipment with Intel’s silicon and Capgemini’s Open RAN network functions. Specifically, Intel\u00ae Xeon\u00ae Scalable processors, PTP-enabled network interface cards (NICs), and the Intel vRAN Accelerator ACC100 Adapter<\/a>, all leveraged by the FlexRAN<\/a>\u2122<\/a> layer 1 software<\/a>. Capgemini provided the vCU and vDU Open RAN network functions, and Microsoft provided the cloud-managed platform through AODS.<\/p>\n\n\n\n

\"Hardware<\/figure>\n\n\n\n

Figure 1:<\/strong> Hardware setup of the live demonstration of carrier-grade cloud-managed Open RAN platform at MWC 2022.<\/em><\/p>\n\n\n\n

The setup included four commercial off-the-shelf servers connected to a top-of-rack (ToR) and management switch. A radio unit (RU), capable of 4×4 multiple input, multiple output (MIMO) over a 100 MHz channel, was connected to the ToR using 7.2 times front-haul interface. A grandmaster clock was also connected to the ToR switch providing PTP synchronization to the RU and the servers. A 5G smartphone device was used to connect to the network. We showed how with AODS we can connect all these together and deploy a virtualized RAN from a cloud with a few mouse clicks and manage it remotely. Such a seamless deployment process reduces the integration efforts that have to be done by vendors, allowing them to focus on innovation instead.<\/p>\n\n\n\n

Here you can view a video of the demo<\/a>. In particular, notice the live analytics this system provides. We will have more to say about that in an upcoming article.<\/p>\n\n\n\n

Looking ahead<\/h2>\n\n\n\n

Along with our partners, Microsoft is bringing to life carrier-grade edge-cloud solutions that empower operators globally to deploy Open RAN network functions easily and securely. Our tools and services can manage RAN deployments at scale. With Azure machine learning and AI, a core component of our technologies, operators can perform analytics that optimize performance, improve management, and proactively detect and solve problems.<\/p>\n\n\n\n

Security principles<\/a> designed for the cloud are being adopted to make the platform resilient, to prevent, detect, and respond to threats in the network and across the firmware and telecommunications supply chains. Edge and network monitoring and programmability via open API’s will enable a new generation of 5G applications while simultaneously improving operational efficiency. Operators can increase revenues and reduce infrastructure costs while building future-proof solutions.<\/p>\n\n\n\n

As we begin to build on our promise, we encourage operators and ecosystem partners to contact us<\/a> to learn more.<\/p>\n","protected":false},"excerpt":{"rendered":"
