To power immersive mobile experiences in 5G, Samsung has introduced advanced 5G solutions that include new baseband units and radios. Among these 5G radios, Massive Multi-Input Multi-Output (MIMO) radios are one of the most attractive options for mobile operators looking to deploy or enhance their 5G networks. The massive MIMO radio is a breakthrough solution that is equipped with a lot of antennas for better coverage and more capacity than a radio. As 5G networks continue to expand around the world using mid-band spectrum, 5G Massive MIMO radios with hundreds of antennas are commonly deployed in the market to help handle the growth in mobile data traffic.

To develop these powerful 5G Massive MIMO radios, numerous tests must be conducted to inspect the products for performance and reliability. One of the tests is conducted at a special facility called an anechoic chamber. Samsung Electronics has several anechoic chambers that are used to analyze and test the antenna performance of its radios. Recently, the company opened a large anechoic chamber at its Digital City campus in Suwon, Korea in order to enhance its ability to introduce more advanced and compelling 5G solutions to its customers.

The newly added non-reflective chamber in Samsung’s Digital City is the size of a basketball court. Beneath the reflector, the engineer looks as small as an insect!

Samsung’s anechoic chambers are also able to cover a wide range of spectrum across low, mid and high-bands. This is especially useful in evaluating 5G radio performance since 5G spans various spectrum bands. Specifically, Samsung’s facilities have the ability to test mmWave antennas, which power high-capacity 5G mobile services. The mmWave spectrum is not used in 4G technology but is crucial to supporting immersive 5G use cases due to its wide-bandwidth.

By enabling tests to be conducted using a range of spectrum, the data sets collected in this way will help Samsung’s engineers verify and analyze a very high number of radio patterns. Based on the findings, engineers are able to refine and improve 5G radio performance to deliver best-in-class solutions for mobile services.

“We are extending our capabilities by developing powerful 5G solutions with the newly added anechoic chamber,” said Seunghwan Yoon, Vice President and Head of the RF Lab at Samsung Electronics’ Networks Business. “With vigorous quality control and verification processes, we look forward to bringing the full benefits of cutting-edge 5G solutions to more users for immersive mobile experiences.”

Better, More Powerful and Reliable 5G Solutions

The establishment of anechoic chambers is part of Samsung’s ongoing efforts to provide superior, reliable 5G solutions that deliver ultra-fast connectivity to users. These chambers help Samsung develop innovative antenna systems tailored to advanced 5G solutions in a wide array of spectrum bands. By leveraging a range of tools and facilities like anechoic chambers, Samsung looks forward to delivering leading-edge 5G solutions that offer consumers and enterprises around the globe new and immersive mobile experiences.

The demonstration leveraged E-UTRAN New Radio Dual Connectivity (EN-DC) technology combining 40MHz of 4G frequency and 100MHz of 5G frequency on the C-Band spectrum. Through the dual connectivity approach, Samsung achieved 2.25Gbps overall on a single user device. For the demonstration, Samsung used its latest virtualized RAN, C-Band 64T64R Massive MIMO radio, and cloud-native 5G Core. Samsung’s vRAN, which is already in use providing services on low-band spectrum in the U.S., proved its capability to support Massive MIMO radios through this achievement.

“By combining our true vRAN solution and powerful C-Band 64T64R Massive MIMO radio for the first time in the industry, Samsung achieved a significant breakthrough, increasing the throughput ten-fold, improving user experience and showing our leadership in virtualized technology,” said Junehee Lee, Executive Vice President and Head of R&D, Networks Business at Samsung Electronics. “This milestone is a result of Samsung’s ongoing efforts in 5G innovation, backed by global commercialization experience, and we aim to continue driving R&D efforts to help mobile operators deliver pioneering solutions.”

Samsung’s vRAN solution enables mobile operators to bring greater flexibility, scalability, and resource efficiency in network management with various spectrums in Time Division Duplex(TDD) and Frequency Division Duplex(FDD). Today’s solution is significant as it demonstrates how the company’s vRAN delivers performance parity with traditional hardware-based equipment, while covering spectrum from low-band to mid-band, and supporting both outdoor and indoor radio solutions for both carrier and private networks.

“Operators consistently tell us that RAN virtualization is a priority as they look to accelerate their 5G network and service deployments,” said Peter Jarich, Head of GSMA Intelligence. “Samsung’s latest demonstrations will be well-received, signaling that 5G vRAN is a viable option, achieving performance on par with purpose-built hardware.”

Samsung recently announced its complete C-Band solutions portfolio, including macro and micro radios, indoor solutions, network optimization tools as well as C-Band Massive MIMO radio which has already been commercially shipped to the U.S. The company’s 5G vRAN solution was rolled out last year, delivering the industry’s first wide-scale commercialization of a fully virtualized 5G network solution.

Samsung has pioneered the successful delivery of 5G end-to-end solutions including chipsets, radios, and core. Through ongoing research and development, Samsung drives the industry to advance 5G networks with its market-leading product portfolio from fully virtualized RAN and Core to private network solutions and AI-powered automation tools. The company is currently providing network solutions to mobile operators that deliver connectivity to hundreds of millions of users around the world.
