Samsung achieves 5G mmWave speeds of 8.5 Gbps using MIMO over 1K antenna elements
Samsung Electronics claims it achieved the industry’s fastest 5G speeds in a lab demonstration that used carrier aggregation to combine multiple channels of mmWave spectrum into 800 MHz. The trial used the Samsung 5G mmWave access unit that combines the traditional baseband, radio and antenna.
Using two test mobile devices, the demonstration achieved approximately 4.3Gbps speeds on each, reaching an industry peak speed of 8.5Gbps across both devices. In order to achieve the speed, two key technologies were used: carrier aggregation and MU-MIMO. Samsung’s 5G NR mmWave Access Unit uses MIMO technology with over 1,000 antenna elements in a single unit. It was announced at MWC-LA-2019.

Earlier this year, Samsung participated in a 5G trial with Verizon, using a commercial network cell site in Texas. In that trial, Verizon aggregated 800 MHz of 28 GHz band spectrum using Samsung’s 5G NR access unit. However, the parties didn’t specify how much traffic the site was handling. It likely wasn’t handling too much commercial traffic, given the scarcity of 5G handsets in use by consumers. Verizon said it has commercially deployed the Samsung 5G NR access unit in its 5G network.
Samsung says that the wide bandwidth from mmWave spectrum enables mobile operators to provide multi-gigabit speeds that lower band spectrums are unable to match. With multi-gigabit speeds, users can experience transformational 5G mobile services. Mobile operators will be able to deliver new and rich services such as 8K video streaming, AR remote learning and holistic VR teleconferencing as well as new use cases that are yet to be imagined.
Today, a number of countries – including Japan, South Korea, and the U.S. – have already assigned 5G mmWave spectrum, and two of them have already launched their commercial 5G services using the spectrum. Also, more than 15 nations are expected to join the 5G mmWave club in the coming years.
“Samsung will continue to be at the forefront in advancing 5G mmWave technology,” said Hyunho Park, Senior Vice President, Networks Business at Samsung Electronics. “This successful demonstration proves mmWave’s potential to deliver new kinds of business use cases and open up opportunities for mobile operators. We look forward to building on this significant technical breakthrough to fuel our continuous journey towards an innovative and vibrant mmWave ecosystem.”
Samsung has been supporting 5G commercial services in leading markets, including Korea and the U.S., currently two of the largest commercial deployments in 5G subscriber count. It is now also actively supporting the commercial deployment of 5G in Japan. Finally, Samsung is also expanding its global 5G market footprint rapidly to new markets including Canada and New Zealand.

Millimeter wave provides the multi-Gbps device speeds associated with 5G, and as such, it has been an instrumental part of operator’s go-to-market strategies in the U.S and continues to expand globally. With established mobile and fixed wireless access use cases, how will 5G in millimeter wave spectrum continue to evolve and better serve users?
In recent demonstrations, Qualcomm explored what’s next for 5G mmWave, including how integrated access and backhaul (IAB) can take cost out of network deployments; the role of multiple transmission and reception points (multi-TRP) in solving for line-of-sight challenges; and, on the device side, power savings from Wake-up Signal and, carrier aggregation enhancements.

WRC-19 identified new frequency bands 24.25-27.5 GHz, 37-43.5 GHz, 45.5-47 GHz, 47.2-48.2 and 66-71 GHz for the deployment of 5G (IMT 2020) radio access networks. Those frequencies will be included in a new version of ITU-R M.1036 recommendation.
ITU-R M.1036 will specify the frequency bands for IMT 2020 RIT/SRITs as well as all other IMT recommendations (e.g. IMT-2000, IMT-Advanced, etc).
