Samsung is the global leader in the fully-virtualized 5G RAN market.¹ The company’s achievement was driven by its 5G vRAN solution, which has been deployed around the world, making Samsung the only major network vendor to have delivered fully-virtualized commercial RAN deployments in North America, Europe and Asia.

Samsung delivered its 5G vRAN solutions for a large-scale commercial network service in the U.S. that launched in December 2020, providing reliable mobile services to millions of users. The company continues to expand its 5G vRAN footprint, with recent milestones including:

• Achieved 2.25Gbps on a single user device with dual connectivity using vRAN and Massive MIMO radios on C-band spectrum in June 2021
• Successfully launched commercial vRAN over C-band using 64T64R Massive MIMO radios in the U.S. in January 2022
• Switched on the UK’s first 5G Open RAN site and the world’s first 5G Standalone (SA) Open RAN site in Japan — both powered by Samsung’s vRAN

Samsung’s commercially-proven network solutions range from traditional RAN to virtualized RAN to Open RAN — supporting operators’ 5G path of choice. To advance virtualization and openness, Samsung’s 5G vRAN splits the baseband functions into a fully disaggregated virtualized Distributed Unit (vDU) and virtualized Central Unit (vCU). The key to this disaggregated architecture is that the RAN software is separated from customized hardware and runs on commercial off-the-shelf (COTS) servers. Samsung’s vRAN also supports O-RAN specifications, “opening up” interfaces between baseband unit and radios, allowing integration from different vendors.

“While many vendors claim they support Open RAN by starting with the RAN Intelligent Controller (RIC), in reality, this is still far from commercialization in large-scale networks and sidesteps the most important part of the Open RAN revolution — which starts from the disaggregation of hardware and software in the baseband, and also involves opening of the fronthaul,” said Woojune Kim, Executive Vice President, Head of Global Sales & Marketing, Networks Business at Samsung Electronics.

Samsung’s vRAN solution fully disaggregates the hardware and software in the baseband, and can support the open fronthaul interface. The company’s O-RAN compliant 5G vRAN solutions are deployed commercially in Japan and U.K. networks, offering seamless integration with other vendors’ radios.

Added Kim: “What differentiates Samsung is a combination of consistent innovation and large-scale commercial experience with leading Tier One operators around the world. This has helped us lead the advancement of vRAN and Open RAN beyond lab tests and field trials, and into major commercial markets. Now, the creation of this vRAN ecosystem will drive innovation to the next level, unlocking numerous opportunities ahead for network industry players and helping operators scale their businesses.”

Samsung’s 5G vRAN consists of a virtualized Central Unit (vCU), a virtualized Distributed Unit (vDU), and a wide range of radio units to enable a smooth migration to 5G. By replacing the dedicated baseband hardware used in a traditional RAN architecture with software elements on a general-purpose computing platform, mobile operators can scale 5G capacity and performance more easily, add new features quickly, and have flexibility to support multiple architectures.

It can also reduce maintenance costs by moving to a COTS (commercial off-the-shelf) x86-based platform, while matching the reliability of a traditional RAN. COTS x86-based servers are standard and readily available computing elements from a large supplier ecosystem. Operators use them today for a range of IT needs.

“Samsung’s 5G vRAN validates a software-based alternative to vendor-specific hardware, while offering high performance, flexibility, and stability,” said Jaeho Jeon, Executive Vice President and Head of R&D, Networks Business at Samsung Electronics. “Once the solution becomes commercially available this quarter, we look forward to providing carriers with additional architectural options for building innovative and open 5G networks.”

Samsung’s 5G vCU was first commercialized in April 2019 and is currently in commercial use by mobile carriers in Japan, Korea, and the United States. This new solution adds the vDU in addition to the vCU to deliver a fully-virtualized 5G vRAN. When combined with Samsung’s virtualized 4G/5G Core, the operator will be able to implement an end-to-end software-based radio and core network running on COTS x86 servers. The company will continue to conduct vDU field trials in North America in the second half of this year.

Designed for 5G Expansion

The recent surge in broadband—especially high-quality video streaming to support work, entertainment, and learn-at-home demands—has highlighted the need for carriers to be able to quickly deploy network resources to meet the shifting requirements of businesses and consumers. Samsung’s vRAN solution, with its easy expandability and manageability, is able to support operators who want to rapidly expand their network capacity and features, and also evolve their networks with 5G-powered capabilities to support these demands.

“Now, more than ever, mobile operators recognize the need for quality-driven, flexible, scalable, and cost-efficient network architectures while planning for 5G network success,” said Peter Jarich, Head of GSMA Intelligence. “RAN virtualization will be an important tool in helping to deliver on those demands and Samsung’s continuing vRAN innovation positions it well to deliver.”

Samsung’s vRAN operates on x86-based COTS servers, either with or without hardware accelerators depending on factors such as total bandwidth.

Verified Performance

Samsung demonstrated its vRAN capabilities to customers in April 2020, proving the feasibility of full virtualization by operating 5G New Radio (NR) baseband functions in software running on an x86-based COTS server.

The demonstration results had matched the performance of legacy hardware baseband.¹ It used Samsung’s field-proven cellular algorithms while testing Dynamic Spectrum Sharing (DSS), a technology that helps carriers take advantage of 5G in 4G frequency bands and advance a seamless evolution to next-generation communications.

Samsung is a pioneer in the successful delivery of 5G end-to-end solutions ranging from chipset, radio, and core network to cloud platform for both mid-band and mmWave spectrum. The company has been supporting 5G commercial services in leading markets, including Korea, U.S., and most recently Japan, where the majority of worldwide 5G subscribers are currently located. In addition, Samsung is further expanding its global footprint rapidly to new markets from Europe to Canada and New Zealand.
