Low power Wi-Fi signals might give future smartphones X-ray vision

Researchers at MIT have created a new system that can be used in future electronics to potentially give people X-ray vision. Dina Katabi, a professor in MIT’s Department of Electrical Engineering and Computer Science, and graduate student Fadel Adib, used low-power Wi-Fi signals to track human movement behind walls. The system is radically different from previous efforts, which have relied on expensive radar technology. Katabi’s system, known as Wi-Vi, transmits a low-power Wi-Fi signal that reflects off of people and can be used to the track them. More →
