ABSTRACT
RF signals can be leveraged for many sensing and monitoring tasks in industrial, home, or robot applications. Despite the advantages of leveraging WiFi sensing modality, no versatile WiFi sensors are available. We develop WiROS to address this immediate need. We leverage the robot operating system (ROS) framework to expose real-time WiFi sensing information to an end-user. Specifically, we demonstrate a plug-and-play toolbox providing access to coarse-grained WiFi signal strength (RSSI), fine-grained WiFi channel state information (CSI), and other MAC-layer information (device address, packet id’s or frequency-channel information). Additionally, we opensource state-of-art algorithms to calibrate and process WiFi measurements to intuitively visualize/debug measurements and measure signal path parameters like the signal’s angles of arrival or departure.
