Japan's NTT DoCoMo has announced a new milestone in 5G joint trials with Huawei in Tokyo, achieving high-speed data transmission over a distance of 1.2km using 28-GHz millimeter wave spectrum.
The trial involved the use of a 28-GHz base station installed on the Tokyo Skytree viewing deck in downtown Tokyo at a height of 340m above ground. User equipment was placed on the roof of a shopping facility at nearby Asakusa Station.
The trial achieved more than 4.52Gbps downlink and 1.55Gbps uplink despite a 10dBm penetration loss caused by the window glass of the viewing deck.
During the trial visitors were shown a demonstration of next generation video communication using a Microsoft HoloLens augmented reality device over the end-to-end 5G network.
“The high-speed and long distance support is one of important technical challenges for 5G mmWave conditions,” commented Gan Bin, VP of Huawei's 5G product line.
“This successful long distance live-demo on a 5G mmWave is a groundbreaking achievement in our joint effort with NTT DOCOMO to build a fundamental 5G commercial environment. This success makes us more confident in realizing the goal of commercializing 5G by 2020."
