Huawei, DOCOMO claim ‘milestone’ in successful 28GHz mmWave trail

7 Dec 2017

In a press release, Chinese equipment maker Huawei Technologies and Japan’s largest mobile operator by subscribers, NTT DOCOMO, have announced reaching a ‘milestone in their joint 5G trials by [successfully completing] high speed data transmission over a distance of 1.2km on the 28GHz millimetre wave (mmWave) spectrum’. Huawei notes that the field trial at Tokyo Skytree in downtown Tokyo, ‘achieved more than a 4.52Gbps downlink throughput and a 1.55Gbps uplink throughput with a coverage range of 1.2km’. In the trials, the Chinese firm supplied one of its 5G base stations which supports Massive MIMO and beamforming technologies. In addition, it also provided the 5G core network and 5G mmWave test user equipment (TUE) used in the tests.

Commenting on the development, Gan Bin, vice president of Huawei 5G Product Line said: ‘The high speed and long-distance support is one of [the] important technical challenges for 5G mmWave conditions. This successful long-distance live-demo on a 5G mmWave is a ground-breaking achievement in our joint effort with NTT DOCOMO to build a fundamental 5G commercial environment. This success makes us more confident in realising the goal of commercialising 5G by 2020.’
