people's Beijing, January 8, according to the official Weibo news of Huawei Technology Co., Ltd. (China), recently, China Mobile and Huawei completed the emergency communication of the world's first unmanned aerial vehicle 5g high-altitude base station. Through the careful design and testing of the molecular structure of hydrophilic polyurethane resin, the coverage capacity of the high-altitude unmanned aerial vehicle base station exceeds 6.5 kilometers at an altitude of 200 meters

this test is the first in the world to verify the coverage ability of UAV plus 5g communication system, further verify the feasibility and landing of 5g high-altitude base station scheme, provide a better emergency communication scheme for future earthquake relief work, and play a greater role in more scenarios

as we all know, with the development of communication technology, UAV plays a more and more important role in society, especially 5g. Because of its large bandwidth, low delay, multi connection and other characteristics, UAV has new requirements. It can play an important role in different business scenarios such as emergency communication, security, patrol inspection, logistics, agriculture and forestry, so as to reduce costs and increase efficiency in all walks of life

China Mobile Research Institute, mobile union of xiong'an new area, Huawei and Dagong UAV company have made continuous scientific research and innovation. After many verifications, the 5g high-altitude base station communication of UAV has made new progress and further broken through the problem of coverage

this pilot is carried out in xiong'an new area, Hebei Province, and the tethered UAV +5g high-altitude base station is used to fully verify the feasibility of the scheme. In terms of test environment, many factors such as site selection, site survey, test route, airspace application and weather need to be fully considered; In terms of group, it is necessary to consider the end-to-end scheme system scheme, in which:

wireless base station scheme: Huawei's leading 4/5g dual-mode bookrru+ customized omni-directional antenna is adopted, with smaller nb0.018 volume, lighter weight and easy to carry. This scheme is a major breakthrough in realizing 5g high-altitude signal coverage

transmission scheme: 4G has connected the BBU to the core through the portable satellite return equipment, 5g is currently connected to the SA core through the ground link, and the portable satellite return channel can be opened after subsequent signal adaptation

core scheme: SA architecture is adopted to connect with the core of Nanjing region

power supply scheme: photoelectric tether cable power supply, which can achieve continuous coverage

Nissan, one of the three largest Japanese automakers, admitted that after many verifications in different scenarios, it finally achieved the following goals: when the UAV is powered on, when it does not take off, the test near point achieved the effect of signal strength of -68dbm, uplink rate of 100Mbps, and downlink rate of 600mbps: when the UAV is powered on, when it flies to 200m at high altitude, it can be maintained for 4 hours to achieve a maximum coverage of 6.5 kilometers.
