In addition to autonomous car operation, in many cases it is desirable to let a human drive the vehicle remotely. To make remote operation possible, it is very critical to have a low and predictable latency to transmit video from the car cameras and receive control commands back. In this paper, we analyze the problem and present a communication and video streaming system that addresses the latency challenges and enables teleoperation of a real car over commercially available LTE network; demonstrating sub-50ms roundtrip latencies for 720p, 60FPS video, with average PSNR 36db.
