802.11ax Wi-Fi Channel State Information (CSI) Measurements for Wireless Sensing

The dataset contains many CSI traces collected in an indoor environment in the presence of a varying number of people. All the data were collected with commercial Wi-Fi systems using IEEE 802.11ax and 20/40/80-MHz-wide channels.

If you use this dataset, please cite our work as one of the associated publications.
