Development of this technology goes back at least as far as July 2005, where researchers claimed at an IEEE Symposium that they had created an ultra-wideband high-resolution short pulse imaging radar system operating around 10 GHz. The applications for which were explicitly for military and police use, providing them with “enhanced situation awareness.”...
“The past two years have seen an explosion of methods for passive Wi-Fi imaging.”.. In a 2021 company blog, Liu discusses the development of IEEE 802.11bf, a new WiFi protocol, which is aimed at standardizing WiFi imaging across all devices – thus making it easier for companies such as his to exploit compatible wireless networks...
The perfect WiFi imaging system may have just been introduced to the world in December 2022, when researchers from Carnegie Mellon University married the latest in WiFi sensing technology to a human form estimation engine known as DensePose.
DensePose is a technology developed by Meta/Facebook, beginning in 2018. It’s very similar to the WiPose system we previously discussed and aims at “mapping all human pixels of an RGB image to the 3D surface of a human body.” - https://patriotandliberty.com/the-ai-gods-new-eyes-your-wifi-can-see-you-throughout-your-home/
