Interesting Snippets

Li-Fi is a really neat idea that essentially promises to replace your wireless router with a simple (LED) lightbulb that does double duty, both illuminating your room and sneakily transmitting data. By cycling the light on and off faster than we can see, it produces binary. And binary, of course, is data. It’s basically fiber optics without the fiber, relying instead on line-of-sight. And it works: Li-Fi researchers at the University of Edinburgh led by Li-Fi pioneer Harald Haas have already transformed standard LED bulbs into 130-megabit-per-second routers.
