Abstract

Unmanned aerial vehicle (UAV) transmits data through wireless communication. Due to its small size and strong mobility, UAV can be used as a base station in the air to provide communication services for ground users. Therefore, UAVs can be used in natural disaster rescue, video shooting and other tasks. They can also carry some loads, such as high-definition cameras, infrared cameras, sensors, etc. to transmit and forward data through wireless channels. UAV technology has attracted more and more attention and has become one of the research hotspots in recent years. The cellular network of UAV is studied. The UAV channel is mainly based on line of sight link, and the characteristics of UAV channel transmission are analyzed. The influence of UAV position on the overall performance of the whole communication system is explored, and the transmission and control methods of UAV signal power are discussed.
