CTOnews.com, February 22 (Xinhua) according to the official news of China Unicom, the company launched a core research project in the field of UAV air base station emergency communications last year. After a year of efforts, recently, the core project team of "Research and Development of Emergency Communication system based on Space platform" jointly composed of Henan Unicom and Beijing Unicom has successfully completed the development of the system in Anyang, Henan Province, and can be put into use.

According to reports, the system developed this time is a mobile communication system based on customized medium-sized UAV, which is composed of long-time customized medium-sized UAV, mobile base station and base station return link.

In the case of emergency communication requirements, the system can quickly fly over the target area, and hover in the air to carry out emergency communication support. The system has the ability to deploy fast communication signals in blind areas of mobile communication coverage, which can meet the rapid needs of mobile communication deployment in natural disasters, emergencies and remote areas, and has high flexibility and response speed.

The mobile base station is a 4G / 5G RF baseband integrated base station. Combined with the core network strategy, it can ensure the reasonable and effective use of mobile communication resources according to the application characteristics of emergency communication users, and flexibly realize voice, short message and data services (including the combined use of multiple services) according to the actual needs of users. The base station coverage area of the system can reach 100km2, the average download rate per user is 10Mbps, and the average uplink 1Mbps is. The access voice user capacity can reach 10000 users.

According to the actual situation of emergency communication, the base station return link can choose air-to-ground microwave communication system or satellite communication system, the communication rate is variable from 100Mbps to 5Mbps, and the return distance supports 10 km to unlimited distance, in order to achieve the most effective cost ratio. In addition to completing the emergency communication task of the air base station, the system can also carry out intelligent inspection of long-distance UAV, the flight distance can reach 600-800 km, real-time return video information flight control information, and complete real-time feature target recognition.

China Unicom said that the UAV air base station emergency communication system has been repeatedly verified, the system base station coverage is wide, the ground user experience is stable, and the scheme can be matched with different types of medium-sized UAV to meet the actual needs of customers in different emergency scenarios.

As previously reported by CTOnews.com, China Mobile, China Unicom and China Telecom have launched similar tethered drones, which have been applied in a number of emergency scenarios. However, tethered drones use multi-rotor drones, while China Unicom's new system uses fixed-wing drones, which are expected to be better in terms of flight altitude and coverage.
