LEDs are a fantastic technology. They are more efficient and less polluting than compact fluorescent light bulbs, and come with a host of other advantages. But one advantage that is certainly new to us is the possibility of using them to transmit data.Or at least, so says the Smart Lighting research team at Boston University.
Because LEDs can cycle on and off millions of times per second, they can, in effect, become wireless routers for information transport. So, as long as your device is in a well-lit area of the office, it will automatically have high-speed internet streaming into it.
