A leader in the vRAN market, Samsung has been contributing to the earliest massive commercial adoption of 5G virtualized networks across the world. The company has been the only major vendor that has conducted large-scale commercial vRAN deployments with Tier One operators on multiple continents — in the Americas, Europe and Asia.

“While Samsung’s 5G vRAN has successfully proven its performance by delivering results on par with traditional hardware-based equipment in commercial networks, we are moving fast into the next phase of vRAN software development — Samsung’s vRAN 3.0,” said Ji-Yun Seol, Vice President, Head of Product Strategy, Networks Business at Samsung Electronics. “The software-centric nature of the solution allows us to add these enhanced capabilities — performance optimization and energy efficiency — much faster than traditional RAN hardware. Samsung’s newest features will add tremendous value to operators rapidly shifting to virtualized networks.”

Samsung’s next-level vRAN capabilities include the following:

Performance Optimization

• 200MHz 3 Cell Support
  With a software upgrade, Samsung’s vRAN will be equipped with the ability to provide 3 Cell configuration with 200MHz of bandwidth support using its 64T64R Massive MIMO radios. This is more than triple the radio bandwidth support when compared to its previous generation software, capable of supporting an operator’s entire mid-band 5G spectrum holdings.
• Modem Algorithm Optimization
  Samsung is incorporating a modem algorithm optimization approach to its development roadmap. Unlike a hardware-centric approach, modem algorithm optimization enables operators to receive software tailored to their needs, with only the required features and configurations, allowing for an optimized and efficient use of COTS servers.

Power Savings

• CPU Core Sleep Mode
  Available on Samsung’s vRAN software, this feature reduces power consumption by automatically putting the CPU in “sleep mode” — or turning off unused CPU Cores — during periods of low data traffic. When capacity demand increases again, CPU Cores exit sleep mode.
• Adaptive Core Allocation
  This feature of Samsung’s vRAN software assigns a number of CPU Cores at cell setup proportional to the number of active cells. Unassigned or unused CPU Cores are set to idle mode to reduce power consumption and are activated when capacity demand increases.
• Energy Saving Feature Orchestrator (ESFO)
  ESFO is an orchestration tool that manages multiple energy saving features in one platform, optimizing efficiency with no service interruption. ESFO automatically analyzes hourly traffic patterns and optimizes the operating conditions of each Energy Saving feature, per sector and time zone. The tool constantly updates the multi-level Energy Saving operations of multiple power saving features — such as cell on/off and Tx path on/off — to reflect traffic pattern changes and prior results.

With these enhanced capabilities, Samsung’s vRAN can support smarter management and operation of wide-scale commercial virtualized networks, as more operators seek to meet the next-generation network demands of their customers. Samsung plans to launch its new vRAN capabilities to global operators, beginning its rollout in North America in the first half of 2023.

Technological innovation has been key to Samsung’s leading advancement of virtualized solutions. The evolution of the company’s vRAN solution can be broken down into three different phases, which are outlined below.

□ First-Generation Virtualized RAN – The Virtualized Central Unit (vCU), Commercialized in 2019

Samsung successfully developed its vCU in 2016 to initiate virtualization in mobile networks. The vCU addresses upper layer processing functions in the RAN. It is generally installed in a centralized location of an operator’s network to reduce the number of anchor point handovers, improving network quality and reliability.

The company carried out multiple trials in Korea, Japan and the U.S. using its vCU and in 2019, successfully deployed this solution for the world’s first 5G commercial networks in Korea and the U.S.

□ Second-Generation Virtualized RAN – The Virtualized Distributed Unit (vDU), Commercialized in 2020

Harnessing its decades of experience and long-standing leadership in RAN technology, Samsung developed a vDU using its independently developed software stack to deliver outstanding performance.

The vDU is responsible for real-time processing functions, and can either reside with the vCU, or on-site with the radio. By allowing the vCU and vDU to be placed in different locations, vRAN offers cost-effective deployment and operation that meets a range of speed, latency, throughput and quality requirements.

In 2020, Samsung introduced its fully virtualized end-to-end 5G RAN solution, comprised of a vDU and vCU, which was later rolled out in collaboration with a leading U.S. operator. The solution’s launch made it the first technology of its kind to achieve wide-scale commercialization. Shortly after that, Samsung expanded its vRAN capability to become the first in the industry to provide support for the Massive MIMO radios on mid-band, demonstrating top 5G vRAN speeds. In this trial, Samsung’s vRAN achieved commercial network performance that was on par with traditional hardware-based equipment.

□ Next-Generation Virtualized RAN With Enhanced Capabilities – Increased Capacity With Hardware Accelerators, To Be Commercialized in 2022

This year, Samsung has taken vRAN to the next level with its own software stack along with a hardware accelerator, which further increases the capacity of its vRAN to support more cells. The hardware accelerator is a dedicated device that works with the CPU in COTS server to improve processing capacity.

Recently, Samsung completed the industry’s first vRAN data session over C-Band spectrum in a live network, leveraging its software-based vRAN running on COTS servers with the hardware accelerator. In this trial, which was conducted with a prominent U.S. operator, Samsung achieved speeds close to the theoretical peak.

Samsung’s journey to highly capable vRAN has been a long and challenging one. But now, with the company having delivered vRAN with C-band Massive MIMO support and having conducted a successful live network trial in the U.S., the future of vRAN looks bright.

For this collaboration, Samsung will supply its commercial vRAN solutions and O-RAN compliant radios, covering both low-band and mid-band spectrum. The company’s fully virtualized RAN is software-based and runs on commercial off-the-shelf (COTS) servers, offering features and performance that are equivalent to traditional hardware-based equipment. Using a cloud-native and container-based architecture, Samsung’s vRAN enables more flexible deployments and efficiency in network management for mobile operators.

Among the key benefits of the revolutionary architecture is its automation capabilities, which simplify end-to-end network management. With Samsung’s vRAN, operators can quickly meet the evolving demands of new and existing services with minimal impact on deployment. Samsung will also deliver to Vodafone UK its market leading O-RAN compliant 5G radios, including the latest Massive MIMO radios.

“Vodafone is committed to leading the next wave of digital transformation across Europe, ensuring fast and reliable connectivity for all,” said Johan Wibergh, Chief Technology Officer, Vodafone. “Open RAN, built on strong partnerships, is key to realizing this ambition. Samsung’s innovative solutions and expertise are part of the foundation that is creating this network of the future.”

This collaboration with Vodafone marks a first for Samsung, as the company brings its cloud native virtualized RAN technology to a leading operator’s network in Europe. As acknowledged by many in the industry, virtualized RAN and O-RAN technologies will be important to helping evolve network architectures to power the next generation of 5G applications and services. To this end, Samsung has been continuously leading in vRAN innovation, most recently showing the capability to support the multi-gigabit speeds of Massive MIMO radios on COTS servers (Link).

“We are proud that this collaboration with Vodafone—one of the premier carriers in the world—will be the first scaled deployment of our pioneering 5G technologies in Europe, including vRAN and O-RAN,” said Paul Kyungwhoon Cheun, President and Head of Networks Business at Samsung Electronics. “This is a major step forward, as more operators are transitioning into new RAN technologies to prioritize user experience and efficiency. We look forward to continue leading the way in 5G innovation to meet our customer’s highest standards of performance, functionality and reliability.”
