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.
