Description
XRF55 is a large-scale RF activity dataset that bundles WiFi CSI together with mmWave radar and RFID measurements across 55 indoor human activity classes. It targets RF-based human action recognition at a class scale that is significantly larger than the dozen-or-so classes in earlier CSI datasets, and is intended as a more challenging benchmark for RF foundation-model and self-supervised studies.
Modality / size
- Modality: WiFi CSI + mmWave radar + RFID (multi-modal RF).
- Subjects / scenarios: multiple participants, indoor environments.
- Labels: 55 activity classes.
Used by (papers)
- Cited as a benchmark for large-class RF HAR and for multi-modal RF fusion.
Notes
- Public dataset accompanying the XRF55 paper.
