WebSep 28, 2024 · Over the past decade, WiFi CSI-based device-free sensing technology has shown great potential in smart homes, assisted living, and many other applications. While model-based device-free sensing approaches analyze and recognize human behaviors by constructing mathematical relationships among WiFi devices, environment, human … WebIn wireless communications, channel state information ( CSI) is the known channel properties of a communication link. This information describes how a signal propagates from the transmitter to the receiver and represents the combined effect of, for example, scattering, fading, and power decay with distance. The method is called Channel …

WebMay 15, 2024 · CSI has frequency diversity due to its multipath reflection, and contains more information than RSSI since it uses measurements per Orthogonal Frequency Division Multiplexing (OFDM) from each packet (Bhartia, Chen, Rallapalli, & Qiu, 2011; Yang, Zhou, & Liu, 2013). CSI thus represents a more reliable and precise model for DFWS.
