IEEE Task Force Works on Standard for Light Communications

Soon enough, experts say, we’ll be getting secure, high-speed Internet access from our LED bulbs: in desk lamps, ceiling fixtures, streetlights, and vehicle taillights. The light-communications systems, relying on nanometer waves in the infrared and visible-light portions of the electromagnetic spectrum, are expected to transmit data generated by a microchip fitted into each LED bulb. The system has been coined light fidelity, or Li-Fi, by its inventor, IEEE Fellow Harald Haas.
