Samsung's 5G NR Integrated Radio for mmWave spectrum

At MWC LA last year, Samsung Electronics announced its new 5G New Radio (NR) Access Unit (AU) supporting 28GHz spectrum. This new AU brought together a radio, antenna and digital unit into one compact box, making it according to them, the industry’s first 3GPP compliant integrated radio for mmWave spectrum.


According to Samsung, 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 also able to deliver an 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.

This video explains it nicely.



In addition, Samsung recently also announced that it has achieved the industry’s fastest 5G speeds in a lab demonstration that combined 800MHz of mmWave spectrum with MU-MIMO (Multi-User, Multiple-Input, Multiple-Output) technology, running on their AU.


According to their press release:

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.

This demonstration highlights the key difference of 5G – its use of mmWave spectrum. 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.


Finally, this Tweet by Samsung Network shows how the AU uses an ultra-quiet convection cooling design that lowers operating costs and environmental noise.
