In this work, we evaluate the feasibility of deploying ubiquitous WiFi sensing systems at the
edge and consider the applicability of existing techniques on constrained edge devices and …

Occupancy information is important to building facility managers in terms of building energy
efficiency, indoor environmental quality, comfort conditions, and safety management of …

Passenger counting is crucial for many applications such as vehicle scheduling and traffic
capacity assessment. However, most of the existing solutions are either high-cost, privacy …

Conventionally, Wi-Fi radio signals are widely used for data transmissions in a wireless local
area network (WLAN). Recently, it has been an interesting topic to also apply Wi-Fi radio …

In the last decade, many studies have significantly pushed the limits of wireless device-free
human sensing (WDHS) technology and facilitated various applications, ranging from …

Although many works bring exercise monitoring to smartphone and smartwatch, inertial
sensors used in such systems require device to be in motion to detect exercises. We …

In this paper, we are interested in high-quality imaging of still objects with only received
power measurements of off-the-shelf WiFi transceivers. We show that the scattered WiFi …

This paper presents a novel approach for crowd analytics using a single monostatic
mmWave radar. We propose a new mathematical model that infers the crowd size for …

In this paper, we are interested in startle reflex detection with WiFi signals. We propose that
two parameters related to the received signal bandwidth, maximum normalized bandwidth …

Wi-Fi sensing has enabled many applications due to the increasing number of commercial
Wi-Fi devices and channel state information (CSI) extraction tools. In this paper, we study the …
