This directory contains the Channel State Information (CSI) data acquired from WiFi CSI receiver 2 (NUC2) which was placed 90 degrees to the CSI transmitter (NUC3). The files are in .mat format and each row in the file corresponds to a received CSI packet. Each packet consists of 270 complex CSI values (3 transmit antennas x 3 receive antennas x 30 OFDM subcarriers). This dataset also contains other information such as the activity being performed, timestamp in milliseconds, experiment number, person id, room id, and ground truth XY coordinates of the person in the room. More details on the CSI system and structure of the CSI data are available in the "Methods" and "Experiment Directory" sections of the Data Descriptor, respectively.
