Intelligent UAV Based Flexible 5G Emergency Networks: Field Trial and System Level Results

The commercialization of 5G is increasing in recent days, will provide users with satisfied speed and more reliable QoS. UAV is one possible carrier platform of wireless base stations, provide flexible coverage and wireless services to target users. In this work, we discuss an intelligent UAV based 5G emergency network model, with dedicated base stations, core networks and smart MIMO antennas installed on UAV. As a solution of emergency situation, this model could provide timely access to users with higher speed, more flexible access mode, smart coverage area, customized service and longer time of duration. Field trial and system level simulation have been provided prior to this work and the results seem promising in some key indicators, the coverage area could exceed the radius of 30km, the downlink speed per user could reach 200Mbps when the height is within 4km. The remaining problems of the resource allocation, power control, deployment, etc. are still open for researchers to tackle.
