Kinect-like gesture recognition leveraged from standard WiFi signals

In a clever use of Doppler frequency shifts, computer scientists have shown it’s possible to use the existing WiFi signals around us to detect specific movements without needing sensors on the human body or cameras. The University of Washington researchers behind the development say that with an adapted WiFi router and a few existing wireless […]

WiFi breakthrough: over-and-out for over-and-out

It looks like it could be over-and-out for the two-way radio catchcry “over.” Stanford researchers say an obvious – but until now overlooked – engineering enhancement allows wireless signals to be sent and received simultaneously on a single channel, a breakthrough that will at least double the speed of existing wireless networks. “Textbooks say you […]
