Researchers have developed a novel framework for device-free fall detection using WiFi Channel State Information (CSI). The system employs an Attention-Enhanced CNN-Transformer hybrid architecture to overcome performance degradation in unseen environments. It utilizes a physics-driven Dynamic Variance Gate (DVG) to filter static background noise and amplify human motion, along with physics-aware data augmentation and a Convolutional Block Attention Module (CBAM) for improved feature refinement. The method achieved high accuracy in cross-domain evaluations and was successfully deployed on an edge computing system for continuous, low-latency monitoring. AI
