Various researchers have created ways to transmit wireless information from LED light fittings, to act as a form of enhancement to Wi-Fi based networks known as "Li-Fi." But now engineers at the University of Virginia (U.Va) have come up with a new twist on this theme – they claim to have created an algorithm that makes almost any device fitted with standard visible- light LEDs able to communicate with other equipment with similar LEDs. So, for example, the LED headlights in your car could communicate to the car in front of you through its LED taillights, or the LED display in your clock radio could tell the coffee maker to turn on via its indicator light...
