“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.”

I'd believe it. When I was in the infantry 20 years ago we could see you 3km away with the optics mounted on our machineguns. And several kilometers with cameras mounted on towers. I don't know how far they went but it was at least 5km because we were directing mortar fire with them and that's about the range of the mortar system we were using.
