With the continuous development of 5G technology, 5G drones have also been widely used. In order to achieve comprehensive coverage of digital information infrastructure and give full play to the advantages of mobile communication, it is also necessary to actively study the 5G drone pan-low altitude coverage networking technology to achieve rapid and all-round dissemination of information. Based on the development trend of 5G drone pan-low altitude coverage technology, this paper proposes technical points such as reducing propagation path loss, accurately planning 5G beams, strengthening pan-low altitude interference control, independently arranging 5G airspace resources, and avoiding time slot interference to create an integrated network system to improve its social benefits.
