IEEE 802.11AX CSI Dataset for Human Activity Recognition

The dataset includes channel frequency response (CFR) data collected through an IEEE 802.11ax device for human activity recognition. This is the first dataset for Wi-Fi sensing with the IEEE 802.11ax standard which is the most updated Wi-Fi version available in commercial devices. The dataset has been collected within a single environment considering a single person as the purpose of the study was to evaluate the impact of communication parameters on the performance of sensing algorithms. Three activities have been considered -- walking and running around the room, and staying in place -- and the data in the empty space scenario has also been recorded and made available as part of the dataset. The evaluation has been performed by using the state-of-the-art SHARP algorithm and is presented in the article "Toward Integrated Sensing and Communications in IEEE 802.11bf Wi-Fi Networks" accepted for publication in IEEE Communications Magazine. The CFR data has been collected over an 80 MHz bandwidth channel on the 5 GHz band. For each available OFDMA sub-channel, the complex-valued channel data is recorded. Overall CFR data is available for the 996 OFDMA data sub-channels out of the 1024 sub-channels available (the remaining ones are control sub-channels where the channel reading is not available.If you find the project useful and you use this dataset, please cite our article:@article{meneghello2023toward, author = {Meneghello, Francesca and Chen, Cheng and Cordeiro, Carlos and Restuccia, Francesco}, journal={IEEE Communications Magazine}, title = {{Toward Integrated Sensing and Communications in IEEE 802.11bf Wi-Fi Networks}}, year = {2023}, volume={}, number={}, pages={} }

本数据集收录了通过IEEE 802.11ax设备采集的信道频率响应（CFR）数据，旨在用于人类活动识别。该数据集为首个采用IEEE 802.11ax标准的Wi-Fi感知数据集，该标准为当前商用设备中最新的Wi-Fi版本。数据采集在一个单一的环境中完成，研究对象为单个人，旨在评估通信参数对感知算法性能的影响。数据集涵盖了三种活动：在室内行走和跑步，以及原地站立，空旷空间场景下的数据也被记录并作为数据集的一部分提供。评估过程采用了最先进的SHARP算法，相关成果已发表在《IEEE通信杂志》即将出版的文章《面向IEEE 802.11bf Wi-Fi网络的集成感知与通信》中。CFR数据是在5 GHz频段的80 MHz带宽信道上采集的。对于每个可用的OFDMA子信道，均记录了复数值的信道数据。总体而言，在1024个子信道中，共获得了996个OFDMA数据子信道的CFR数据（其余为控制子信道，其中信道读取不可用）。若本项目对您有所帮助，并在使用本数据集时，请引用我们的文章：@article{meneghello2023toward, author = {Meneghello, Francesca and Chen, Cheng and Cordeiro, Carlos and Restuccia, Francesco}, journal={IEEE Communications Magazine}, title = {{Toward Integrated Sensing and Communications in IEEE 802.11bf Wi-Fi Networks}}, year = {2023}, volume={}, number={}, pages={}}。
