Huawei and NTT DoCoMo marked a milestone in their joint 5G trial by transmitting high-speed data over a distance of 1.2km on the 28-GHz mmWave spectrum band.

The field trial, which took place in downtown Tokyo, was conducted in an environment where a base station was located at Tokyo Skytree’s viewing deck at a height of 340m above the ground, while user equipment was placed on the roof of a shopping facility at Asakusa Station. Under adverse conditions of a -10dBm penetration loss via the window glass of the viewing deck, the companies achieved a downlink speed of more than 4.5 Gbps and an uplink speed of 1.5 Gbps with a coverage range of 1.2km.

Huawei supplied its 5G base station, core network and mmWave test user equipment for the open trial, in which visitors experienced immersive VR video communication using a Microsoft HoloLens over the 5G network.

“The high-speed and long distance support is one of important technical challenges for 5G mmWave conditions,” said Gan Bin, VP of Huawei’s 5G product line.
