60 GHz Millimeter Wave Communication Experiment for Unmanned Aerial Vehicles in Low Altitude Airspace

Unmanned aerial vehicles (UAVs) are crucial in realizing the execution of sensing tasks for digital twin and provision of smart city services in the city airspace without constraints owing to congestion on the ground. Therefore, wireless communication characteristics between UAVs in airspace are important for verifying their practical feasibility. In particular, millimeter wave communication capable of supporting various city services with high traffic loads, emerges as a vital technology for urban airspace services in the 5G era, and beyond. In this study, we conducted real-field experiments to analyze the characteristics of 60 GHz millimeter wave communication standardized by IEEE 802.11ay in airspace using a testbed called the city airspace testbed realized by self-standing smart poles.
