Kumar quoted about RFID tracking drones

Swarun Kumar was recently quoted in TechXplore about RFID tracking drones that are being developed to optimize supply chain management, especially in large warehouses. The drones are intended to read RFID tags from tens of meters away; as of now, researchers are working to account for phase shifts that occur as the drone is moving, which might interfere with a proper RFID detection. What changes here is that one of the ends is battery-free, and they want to location-track the battery-free device, which requires need phase-consistent measurements. These together make the problem quite challenging,” says Kumar. “That's what I think is the conceptual novelty in this work. I anticipate that there might be a lot more applications than the inventory tracking problem—which in and of itself is quite important.
