Using Wi-Fi-like sonar to measure speed and distance of indoor movement

by Matt Shipman, North Carolina State University, TechXplore

Researchers from North Carolina State University have developed a technique for measuring speed and distance in indoor environments, which could be used to improve navigation technologies for robots, drones—or pedestrians trying to find their way around an airport. The technique uses a novel combination of Wi-Fi signals and accelerometer technology to track devices in near-real time.
