| Abstract: |
| In recent years, wireless sensing technology based on channel state information (CSI) has been extensively and exploratorily studied and applied in several directions, such as indoor positioning, activity recognition, and health monitoring. However, the current research primarily relies on the independent collection of CSI data, and presenting a lack of clarity towards the research status of CSI open-source dataset and data acquisition devices/tools. Firstly, the wireless sensing technology based on wireless fidelity (WiFi) CSI is described. Secondly, 9 types of CSI data acquisition devices/tools are introduced in detail and the application directions and research status of CSI are generalized. Thirdly, the CSI open-source datasets of the past five years are aggregated and the limitations and challenges of current research on CSI wireless sensing research are analyzed. Finally, the content of the full text is summarized and the future trend of CSI wireless sensing is prospected. |
