“We developed a deep neural network that maps the phase and amplitude of WiFi signals to UV coordinates within 24 human regions. The results of the study reveal that our model can estimate the dense pose of multiple subjects, with comparable performance to image-based approaches, by utilizing WiFi signals as the only input.”
Yep I have read that sensitive buildings are now built with a hallway ringing the building and offices further inside, so the rooms where classified things are discussed don’t have windows accessible by outside lasers.
