This week’s Question: A PhD student at Eindhoven University of Technology has developed a way of using infrared rays to carry wireless data to a laptop or smartphone. The wireless data comes from central "light antennas" that could, for example, be mounted on a ceiling to direct the rays of light supplied by an optical fiber. With no moving parts, the system requires no power. Project head Tom Koonen estimates that the technology could be installed in homes and stores in five years. What do you think? In five years, will light-enabled Wi-Fi "find a home?"
