With the rapid development of wireless communication technology, various indoor location‐
based services (ILBSs) have gradually penetrated into daily life. Although many other …

Wi-Fi localization and tracking face accuracy limitations dictated by antenna count (for angle-
of-arrival methods) and frequency bandwidth (for time-of-arrival methods). This paper …

Robust and accurate indoor localization has been the goal of several research efforts over
the past decade. Due to the ubiquitous availability of WiFi indoors, many indoor localization …

Over the past decade, WiFi CSI-based device-free sensing technology has shown great
