Samsung Electronics today announced at MWC Los Angeles 2019 its new 5G New Radio (NR) Access Unit (AU) supporting 28GHz spectrum. This new AU brings together a radio, antenna and digital unit into one compact box, making it the industry’s first integrated radio for mmWave spectrum, compliant to the 3GPP NR standard. The new Access Unit is on display at the Samsung Booth (South Hall #1228).

Earlier this year, Samsung Networks successfully deployed its first-generation 5G NR radio base stations in the U.S. with separated radio and digital units (RU-DU separated radio). By integrating these RU-DU technologies with 1,024 antenna elements for mmWave spectrum into one compact box, the new AU can be more easily installed on streetlight poles and building walls, providing operators a faster, simplified way to build out 5G networks.

The AU is able to deliver an industry-leading capacity of 10Gbps throughput, enabling operators to deliver higher 5G NR speeds to more users. Additionally, improved cost-efficiency is achieved by eliminating the need for ‘fronthaul’ fiber connections, thanks to the AU’s integration of the digital unit. Samsung is currently shipping the new AU to a leading U.S. Tier One mobile network operator.

“Samsung has a long history of network innovation. Our innovative spirit has led us to introduce next generation technologies and open up a new 5G era,” said Paul Kyungwhoon Cheun, Executive Vice President and Head of Networks Business at Samsung Electronics. “Cultivating mmWave spectrum provides infinite opportunities by unlocking 5G’s full potential. We’re excited to advance the industry by offering a new vision and diverse options to our customers around the world.”

New SoC Modem Increases 5G’s Efficiency

Additional innovations to Samsung’s new AU are made possible by Samsung’s in-house 5G RF chipset, announced earlier this year and the company’s first 5G NR system-on-a-chip (SoC) modem (S9100), announced today. This chipset enables an approximate 25 percent reduction in size, weight and power consumption, when compared to the same solution without an embedded 5G RF chipset. The AU’s new 5G NR modem substantially increases power efficiency.

Expanding 5G Spectrum Capabilities

In addition to launching the new AU, Samsung is expanding its 5G portfolio to help operators have a wider choice in selecting radio solutions for different deployment scenarios. The company currently has commercial solutions for 2.5GHz, 3.5-4.1GHz, 26-28GHz and 39GHz and today launched a new 5G RFIC chip for the 24-27GHz spectrum, which will support new radios in 2020. The 5G portfolio now includes a mix of integrated and non-integrated architectures as well as transceiver paths (4T4R and 2T2R) to meet multiple deployment scenarios for operators – outdoor pole-mount, strand-mount, in-building, and others.

The demonstration, held at the ‘Korea International Circuit’ racetrack, was made possible by Samsung Networks’ end-to-end 5G mmWave solutions, including 5G New Radio (NR) base stations. The same equipment has been in commercial operation in the United States since the first half of this year.

While the racing car moved at approximately 130 miles per hour (210Km/hour) on the track, the trial verified the stable performance of live downloads, uploads and handovers between 5G cell sites on the racetrack. Download speeds reached up to 1Gbps, demonstrating the capacity for multi-gigabit downloads on a 5G device inside a racing car, using 200MHz bandwidth of 28GHz spectrum.

5G’s high speeds, instantaneous communications, and seamless handovers allow for a more effective and safer way to transfer video to and from cars accelerating up to 130 miles per hour (200~370Km/hour.) The companies were able to use this live video streaming capability to broadcast multiple views of the race in real time over SK Telecom’s live broadcasting solution, T Live Caster 5G.

The test showed that the mmWave technology can unlock the full potential of 5G, for delivering innovative uses cases and business models, such as new entertainment experiences in motor sport events. For example, cameras built into the cars’ cockpits will be able to stream real-time video data from each car over 5G wireless links, allowing viewers to enjoy vivid scenes of the race from the driver’s point of view. Through VR, AR and 360 degree video streams, racing fans will be able to enjoy the immersive experience of feeling as if they are inside an actual moving car.

“5G already opened up a new horizon when the first commercial service started in the first half of 2019 across Korea and the U.S.,” said Jaeho Jeon, Executive Vice President and Head of R&D, Networks Business at Samsung Electronics. “Samsung is at the forefront with global operators in bringing 5G benefits to consumers, industries and societies by helping them deliver 5G commercial networks. This trial is a great example of taking a user experience and the racing industry to new heights.”

“5G commercial service means much more than just faster speeds. It is a vital engine in transforming digital landscapes to bring enhanced and new business models that had only lived in our imagination,” said Park Jin-hyo, Chief Technology Officer and Head of ICT R&D Center of SK Telecom. “We will continue to work closely with Samsung in pushing the limits of legacy technology and maximizing the power of the 5G network.”

In September 2017, Samsung achieved the world’s first 5G handover at 118 miles per hour (190Km/hour) and 1Gbps speed download in a vehicle moving at 127 miles per hour (205Km/hour) in Korea (Link). Based on these achievements, Samsung has advanced network innovation through a comprehensive series of real-world use cases powered by 5G in partnership with global operators, helping to overcome the limits of legacy technology.
