12:25-12:55 h | Virtual

Wi-Fi sensing uses Wi-Fi signal measurements to detect static and dynamic properties of local environment. Using high quality measurements and advance processing techniques, Wi-Fi sensing enables new applications over existing Wi-Fi networks. These applications may include motion detection, proximity detection, healthcare monitoring and indoor automation. Many of these use-cases can be built using existing hardware which provides significant scale advantage over ubiquitous Wi-Fi deployments. In this presenataion, we provide signal model for Wi-Fi sensing and describe different methods and practical considerations for sensing information extraction over a Wi-Fi network and processing techniques. We also discuss suitability of current Wi-Fi standard for sensing and identify possible enhancements for future Wi-Fi standards to improve this use-case. We share results obtained from an experimental sensing system built using 4x4 MIMO Wi-Fi radios operating in an indoor office and home environment.
