Researchers Develop X-Ray Vision with Wi-Fi Do you really wish you had X-ray vision? Sure, it would be fun to see what your neighbors are doing behind those walls — until you see something you wish you hadn’t. Regardless, researchers at MIT have developed a sensing technology that uses low-power Wi-Fi to detect moving people. It follows other wall-penetrating sensor tech using radar and heavy equipment. The Wi-Vi system by Dina Katabi and Fadel Adib sends out a low-power Wi-Fi signal and tracks its reflections to sense people moving around, even if they’re in closed rooms or behind walls. news.cnet/8301-17938_105-57591355-1/can-wi-fi-let-you-see-people-through-walls/#
