Abstract:
The rapid growth in the deployment of unmanned aerial vehicles (UAVs) opens up new paradigms for spectrum sensing, RF actuation, and air-ground communication. In this three-part talk we will cover, from an experimental viewpoint, the challenges in creating intelligent and coordinated UAV swarms that are synchronized in their operation. In the first part, we will show the first of its kind implementation of distributed beamforming with UAVs, with tight constraints on timing and real-time feedback of channel state information. In the second part, we focus on millimeter (mmWave) radio mounted UAVs that can serve as mobile 5G base stations and aerial backhaul links. We will motivate the need for - and then design - new channel models for air-to-air and air-to-ground communication at 60GHz using Facebook’s Terragraph channel sounders that are custom-fitted on DJI M600 UAVs, considering practical limitations of hovering and airframe reflections. In the third part, we shall describe a method that ensures jamming resilient air-ground control channels using a combination of mmWave radar sensing and physical movement of the UAVs that form wireless signal constellations in the air. While concluding, we shall provide a glimpse of other ongoing work in the systems space, including a method for wireless charging of UAVs through magnetic resonant coupling and deploying UAVs within an urban region using an existing public bus transportation network.
