Huawei, in cooperation with Japan’s NTT Docomo, has successfully conducted a live 5G demo using 39 GHz mmWave technology based on 3GPP standard 5G New Radio (NR) current agreements.
In the trial, which took place at the 3rd Global 5G Tokyo Bay Summit, the pair reported that the cell coverage reached up to 2.0 kilometers with Gbps peak throughput for a single user in the mmWave, demonstrating a real-time 3-way 4K video conference.
Takehiro Nakamura, general manager of Docomo’s 5G Laboratory, said “the successful field tests and showcase of the real-time 3-way 4K video conference conducted at 39-GHz high frequency band technology is an important achievement of the 5G joint innovation and field trial between the pair and this breakthrough will have a significant impact moving 5G a step closer to commercialization. “
The test system comprised of one base station that works in the 39 GHz band with 1.4 GHz bandwidth, and 2 UEs (User Equipment) and achieved 1.3 Gbps (MAC Layer) peak throughput for a single user in the high band at a distance of 1.5 kilometers. The test employed key 5G technologies, such as the MMFA (Meta-Material Focal Array) and Polar Code.
