Radar technologies compared for bedroom activity and sleep monitoring

A new research paper compares three different radar technologies—FMCW, IR-UWB, and Wi-Fi sensing—for monitoring human activity and sleep interruptions in bedrooms. The study, which utilized synchronized recordings from 20 participants across various room layouts, evaluated each technology using the same convolutional neural network (CNN). IR-UWB demonstrated the highest performance in activity recognition across different subjects, while FMCW showed better generalization to unseen room layouts. All three technologies achieved over 92% macro F1 for sleep monitoring in new environments, highlighting a trade-off between recognition accuracy and environmental robustness. AI
