# Data and code for " Same Signal, Different Story: Demystifying Receiver Effects in Wi-Fi Channel State Information" The dataset(s) here were collected with a Wi-Fi testbed of eight different receivers: 2x Asus RT-AC86U2x ESP32-S31x Intel IWL53001x Intel AX2101x Qualcomm Atheros QCA AR94621x USRP N2954-R The transmitter for all the datasets is another USRP N2954-R with Wi-Fi frames generated using the MATLAB WLan Toolbox. All data was collected using our python scripts, published on GitHub: https://github.com/nzqo/sensession.Relevant subprojects for CSI extraction are found in `csi_tools` in sensession.You can find the experiment design (e.g., frame precoding) by inspecting the `/experiments` directory.Evaluation scripts of the data are also shared in the `/evaluation` directory. ## Format All data is stored as `.parquet` files, which is tabular data. Each line contains a single CSI recording. The `meta_id` column marks a group (a coherent recording), with further information linked in the corresponding `meta.parquet` files. These files can be easily loaded into dataframes using e.g. pandas or polars. Every CSI value is represented as a nested list corresponding to shape …
