Wi-Fi, you cannot see it, or feel it, but it is there. It brings data to and from your phone, laptop, and other devices. It travels at the speed of light through darkness, rain, and walls! Although we cannot see Wi-Fi, Wi-Fi can be used to monitor us and our environment. (Wi-Fi can even be used for activity recognition and to measure breath and heart rate!)

Explore this interactive poster exhibition to learn how Wi-Fi monitoring works, what applications are underway, and vote on what you think about this technology. Your opinions will have a direct impact on European research on this technology.
