The evolution of mobile network technology has changed our lives gradually and dramatically. Such progress has seeped into our everyday lives and changed the way we communicate, spend our free time, and how we work.

Until the year 2010, communication was mostly voice and text-based. Over the past 13 years, we’ve seen consistent technology advancements from 4G to 5G and beyond, and we’re now able to enjoy ultra-high-definition, large-capacity multimedia content, anytime, anywhere.

Mobile network technology has redefined the cultural landscape of connections at all levels — between people to people, business to business and industry to industry.

Software Is at the Heart of Mobile Network Evolution, Moving Toward Virtualization

At Samsung, we have been focused on identifying the key technology that will drive mobile network transformation and we think the answer is software.

Venture capitalist Marc Andreessen once said, “software is eating the world.” Just like this famous phrase, global industries are being ‘eaten’ by software and this dynamic transition is called ‘virtualization’ in the network infrastructure world. Whereas hardware is the foundation for traditional networks, virtualization is all about shifting to software.

Virtualization lets you transform many hardware functions and features into software, allowing various services to run on a single hardware platform. Simply put, it works similar to downloading and regularly updating a range of apps on your smartphone.

vRAN Will Eat up the Network Infrastructure World

Samsung has been spearheading the shift toward network virtualization and openness. We introduced the first fully virtualized Radio Access Network also known as vRAN. Although vRAN currently accounts for just 3 percent¹ of the global RAN market, it is a pioneering technology that the industry is watching closely.

Samsung has been a forerunner in the innovative path to vRAN, proving our outstanding performance and wide-scale commercialization capabilities in the real-world, leading expansion in major 5G markets, including Asia, Europe and North America.

We supported the largest-scale commercial vRAN for the first time in the world with Verizon in 2020, and since then, have been providing stable and reliable 5G services to millions of customers. We also began our collaboration with DISH Wireless and Vodafone Group, actively expanding our vRAN footprint to new markets, including the U.K., Germany and beyond.

With the innovations that we are bringing to virtualization, we are creating the blueprint for next-generation networks. We are not only committed to advancing our technology, but more importantly, onboarding and growing the best software talents, which we believe is a central pillar to our achievements.

Samsung Networks Chipset: Packaging the Essence of Our Innovation and Technological Capabilities

The power of chipsets not only radiates through hardware-based networks, but also in software-centric virtualized architectures. While most functions and features are being turned into software, there are still integral parts of the network that remain as hardware. Therefore, the ability to pack advanced features into a tiny chipset is one of our invaluable asset.

Our competitive advantage stems from our unique combination of expertise in innovative software solutions and our comprehensive portfolio of hardware combined with our 5G network chipsets.

Samsung is the only major network vendor that has the capability to design, develop and manufacture 4G and 5G network chipsets in-house.

With the rising market demand for higher energy efficiency, as well as support for complex spectrum bands and reduced hardware footprint, there has been a stronger emphasis on chipset technologies.

Compared to previous generations, our latest 5G chipset reduces base station energy consumption by about 40 percent and antenna size by nearly half compared to previous products, and also includes support for multiple spectrum bands.

With a strong foundation built on over 40 years of experience in network technologies, we have managed to stay ahead of evolving market demands, introducing a compact and lightweight radio with high performance and energy efficiency.

Building a Better Tomorrow With Energy Savings Technology

The true value of innovation is not just about advancing technology, but it’s also about pursuing a better tomorrow. Ranging from software to AI and chipsets, sustainability has always been at the core of our product development strategy. Bringing our sustainability vision to life, we are introducing our newest energy saving features for vRAN at MWC this year.

As legendary hockey player Wayne Gretzky once said, “a good hockey player plays where the puck is. A great hockey player plays where the puck is going to be.”

As we continue along our exciting journey, Samsung will always think a step ahead, anticipating future needs of our customers. And, as a pioneer in the mobile network industry, Samsung will continue to drive this paradigm shift by jumpstarting the next wave of unforeseen innovation.

Next-Level Capabilities With a Wide Range of Support

Leading global operators choose Samsung’s vRAN for its ensured quality, credibility and robustness, delivering performance similar to that of traditional hardware-based equipment. The company’s vRAN is primed to support mobile operators and enterprises with its ability to cover a wide range of spectrums—from low-band to mid-band—as well as its flexibility in terms of supporting solutions for both outdoor and indoor environments.

“Using the company’s own independently developed end-to-end vRAN software stack, Samsung’s solution boosts network performance and brings agility to the network. This in-house technology is the key feature of Samsung’s vRAN that distinguishes our solution from others in the industry,” said Junehee Lee, Executive Vice President and Head of R&D, Networks Business at Samsung Electronics. “As a global leader in vRAN technology, we will continue to strengthen our vRAN capabilities, while aiming to maintain strong leadership in virtualized networks and redefining what is possible for 5G networks.”

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.
