Collection description

This database collects the channel frequency response (CFR) vectors captured through the Nexmon CSI extraction tool from an Asus RT-AC86U IEEE 802.11ac Wi-Fi router working with a total bandwidth of 80 MHz. The dataset is collected in three different environments, i.e., a bedroom, a living room and a University laboratory, while one person performs one among seven activities of interest within the room. The CFR data for the empty room (E) is also provided. We obtained data from three volunteers (a male, and two females) while they were walking (W) or running (R) around, jumping (J) in place, sitting (L) or standing (S) somewhere in the room, sitting down and standing up (C) continuously, and doing arm gym (H). Each CFR sample results in complex-valued channel information from 242 data sub-channels for each transmit-receive antennas pair. In our experiments, with one transmitter antenna and four at the monitoring device, each sample corresponds to four vectors of 242 complex values. Although the total number of sub-channels at 80 MHz is 256, each antenna vector has 242 components as the CFR is only provided for data sub-channels, namely sub-channels whose indexes are {-122, ..., -2} and {2, ..., 122}, i.e., no CFR value is provided for the control sub-channels. For more information about the setup, please, refer to the related publication. This dataset was used to design and assess the performance of SHARP presented in the article ''SHARP: Environment and Person Independent Activity Recognition with Commodity IEEE 802.11 Access Points'' by Francesca Meneghello, Domenico Garlisi, Nicolò Dal Fabbro, Ilenia Tinnirello, Michele Rossi. The Python source code is available at https://github.com/signetlabdei/SHARP.
