With the development of the Internet of Things (IoT), many kinds of wireless signals (eg, Wi-
Fi, LoRa, RFID) are filling our living and working spaces nowadays. Beyond communication …

User identified gesture recognition is a fundamental step towards ubiquitous device-free
sensing. We propose WiHF, which first simultaneously enables cross-domain gesture …

There is a growing literature demonstrating the feasibility of using Radio Frequency (RF)
signals to enable key computer vision tasks in the presence of occlusions and poor lighting …

Wireless sensing has become a hot research topic recently, enabling a large range of
applications. However, due to the intrinsic nature of employing weak target-reflection signal …

Due to the ubiquitous deployment of wireless infrastructures, the radio signal nature of
invisibility, and the elimination of the line-of-sight requirement, it has drawn increasing …

Beamforming can improve the communication and sensing capabilities for a wide range of
IoT applications. However, most existing IoT devices cannot perform beamforming due to …

The past decade's research in RF indoor localization has led to technologies with decimeter-
level accuracy under controlled experimental settings. However, existing solutions are not …

Indoor localization has played a significant role in facilitating a collection of emerging
applications in the past decade. This paper presents a novel indoor localization solution via …

As cameras and Wi-Fi access points are widely deployed in public places, new mobile
applications and services can be developed by connecting live video analytics to the mobile …

Our work demonstrates a new set of silent reconnaissance attacks, which leverages the
presence of commodity WiFi devices to track users inside private homes and offices, without …
