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 to extract the relevant features for analysis.
