Understanding the Mechanism of Through-Wall Wireless Sensing

Abstract: During the last few years, there is a growing interest on the usage of Wi-Fi signals for human activity detection. A large number of Wi-Fi based sensing systems have been developed, including respiration detection, gesture classification, identity recognition, etc. However, the usability and robustness of such systems are still limited, due to the complexity of practical environments. Various pioneering approaches have been proposed to solve this problem, among which the model-based approach is attracting more… Show more

“…To address this issue, we posit that modeling the propagation of CSI in TTW scenarios holds promise as a viable solution. While Zhang et al [35] have aimed at developing a model for estimating CSI in through-wall scenarios, its performance experiences a significant degradation, especially in scenarios featuring reinforced concrete. Hence, our subsequent focus centers on further exploration and refinement of CSI estimation models tailored for TTW scenarios, thereby enhancing the accuracy of the multi-subject pose estimation in TTW scenarios.…”
