Performing Wi-Fi Sensing with Off-the-shelf Smartphones 2020

PerCom 2020 Best Demo Award winner

WiFi sensing has recently attracted a lot of attention in providing a method for device-free sensing with standard WiFi devices through the use of Channel State Information (CSI). However, access to CSI from user-level applications is not provided by most WiFi devices, specifically ubiquitous smartphone devices. In this demonstration, we present our custom developed application for collecting, labeling and processing CSI on-device, in real-time, for standard off-the-shelf Android smartphones. We additionally demonstrate the use of our application on select device-free sensing tasks.
