# Wi6CSI
Wi6CSI: A Human Activity Recognition Dataset for Next-Generation WiFi Sensing in the 6 GHz Band

## Wi6CSI Dataset Overview

**Wi6CSI** is a comprehensive Wi-Fi sensing dataset collected in the **6GHz** band. It offers a rich, high-resolution resource for researchers

### Key Features

- **Scenarios Covered:**
  - **Single User:** Data captured with one user performing various activities.
  - **Multi User:** Data where multiple users are present simultaneously.
  - **People Counting:** Scenarios designed to count individuals within a specific area.

- **Collection Locations:**  
  Data has been collected across **three distinct locations**, ensuring diverse environmental conditions and variations in the wireless channel.

- **Data Volume and Resolution:**  
  - The dataset holds approximately **1.5TB** of data.
  - Each Wi-Fi packet includes **8100 subcarriers**, offering a level of detail that supports high-resolution sensing and analysis.

- **Wi-Fi Band:**  
  - Utilizes the **6GHz** frequency band, providing enhanced granularity and improved sensing accuracy compared to lower frequency bands.

### Dataset Contents

- **.mp4 files:**  
  These files are Pose3D videos that capture 3D representations of subjects during data collection. They can be used for visual analysis, activity recognition, or correlating motion with CSI data.

- **.mat files:**  
  These MATLAB files contain the Wi-Fi CSI values. The numerical data stored in these files represent the channel state information of the wireless signal, useful for signal processing or machine learning applications.

- **.csi files:**  
  These files hold raw Wi-Fi CSI data. They are not immediately usable and must be parsed using the [picoscenes toolbox](https://ps.zpj.io/matlab.html) to extract the relevant features for analysis.
