Reliability of Wireless Communication Systems for Drones

Recently, UAVs (Unmanned Aerial Vehicles), also known as drones, are becoming increasingly popular due to their lower prices and higher performance. On the other hand, the aviation law and local government regulations have become stricter due to a decline in user morale, and a registration system for aircraft and pilot licenses are being introduced. In addition, there are cases where multiple drones are operated simultaneously, and radio interference from other radio equipment and high-frequency power sources is occurring. As a result, control signals and video signals are disrupted, causing crashes. This paper provides an overview of commercially available wireless communication systems for drones and conducts a survey of actual measurements of drone communication in the 2.4 GHz band. Furthermore, the radio propagation characteristics are verified by simulation, and future drone communications are discussed.
