# 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. |
