Transmitting Data at the Cost of Light

Jul-09-15 A new technology that allows LED bulbs to transmit wireless data could lead to a more cost-effective—and faster—source of wireless communications.

The breakthrough technology relies on a modulation algorithm developed by a team from the University of Virginia, which allows data to be sent via visible light without using any more energy than is required to power the lights. The light waves can transmit up to 300 megabits per second, and can be used by any device with an optical reader.

According to the developers, the technology could conceivably allow any device with an LED light to communicate with another LED-equipped device, such as the LED on an alarm clock triggering the LED-light equipped coffeemaker to begin brewing.
