Controlling electromagnetic waves and information simultaneously by information
metasurfaces is of central importance in modern society. Intelligent metasurfaces are smart …

Mobile network is evolving from a communication-only network towards one with joint
communication and radar/radio sensing (JCAS) capabilities, that we call perceptive mobile …

With the high demand for wireless data traffic, WiFi networks have experienced very rapid
growth, because they provide high throughput and are easy to deploy. Recently, Channel …

Driven by a wide range of real-world applications, significant efforts have recently been
made to explore device-free human activity recognition techniques that utilize the …

There is an increasing need to remotely monitor people in daily life using radio-frequency
probe signals. However, conventional systems can hardly be deployed in real-world settings …

With the advancement of wireless technologies and sensing methodologies, many studies
have shown the success of re-using wireless signals (eg, WiFi) to sense human activities …

In this article, we present a survey of recent advances in passive human behavior
recognition in indoor areas using the channel state information (CSI) of commercial WiFi …

Some pioneer WiFi signal based human activity recognition systems have been proposed.
Their key limitation lies in the lack of a model that can quantitatively correlate CSI dynamics …

In this paper, we propose WifiU, which uses commercial WiFi devices to capture fine-grained
gait patterns to recognize humans. The intuition is that due to the differences in gaits of …

Power delay profiles characterize multipath channel features, which are widely used in
motion-or localization-based applications. Recent studies show that the power delay profile …
