According to news on October 3, China Unicom’s “mobile millimeter wave communication field test” was successfully implemented in Jiangxinzhou, Nanjing. The test uses multi-rotor drones as communication nodes to achieve thousands of meters of air-to-ground, aerial optical precision tracking and millimeter-wave high-bandwidth communications.

test site,A quad-rotor UAV equipped with a tracking and aiming system and an aerial wireless communication base station flies according to the planned route, and at the same time establishes a narrow-beam directional millimeter wave connection with a carrier frequency of 84GHz with the ground mobile base station to build a UAV-based mobile wireless base station., providing high-speed wireless network coverage without fiber guarantee.
A large-scale maneuver test was conducted during the experiment to verify the in-motion communication capability of the high-bandwidth millimeter wave link under the high maneuverability conditions of the drone. The backhaul link communication rate bandwidth between the base station and the base station controller meets the 5G communication requirements.
According to the evaluation of the on-site observation expert group,The test space communication distance, communication bandwidth, number of mobile nodes, etc. are all at the leading level., the test results have strong scientific research value and industrial prospects, can serve mobile communication support, emergency rescue and other applications, and are expected to provide new solutions for future mobile communications.
