“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.”
There is this Home Assistant integration which I remember getting working. I haven’t used Home Assistant in a while though, so I can’t be a good resource if you need any help.
