As part of the Pacific Views: Library Speaker Series, Yasamin Mostofi, a professor in the UCSB Department of Electrical & Computer Engineering, spoke in a talk entitled, "Robotics Meets Wireless Communications Opportunities and Challenges." This lecture explored her work with radio frequency signals.
Radio Frequency signals are everywhere these days. Can they be used for sensing? Do they carry useful information about the objects they visit? For instance, imagine two unmanned vehicles arriving behind thick concrete walls. They have no prior knowledge of the area behind these walls. But they are able to see every square inch of the invisible area through the walls, fully imaging what is on the other side with high accuracy. Can the robots achieve this with only WiFi signals and no other sensors? In another example, consider the WiFi network of a building. Can it estimate the occupancy level of the building and the spatial concentration of the people, without relying on people to carry a device?
In this talk, Mostofi discussed her latest results to achieve these goals. More specifically, she showed that it is possible to achieve x-ray vision with only WiFi signals and drones, and image details through thick concrete walls. Moreover, she also discussed occupancy estimation and showed how to count people with only WiFi measurements.
