Submission + - German Scientists Create 3Gbps Visible Light Network from LED Ceiling Lamps (ispreview.co.uk)

Mark.JUK writes: Scientists working at Berlin’s Fraunhofer Heinrich Hertz Institute in Germany have developed new components that can turn standard “off-the-shelf” LED (Light-Emitting Diode) room lights into an Optical Wireless Local Area Network (OWLAN) that delivers data transmission rates of up to 3Gbps (Gigabits per second).

The new kit is an extension of HHI’s earlier work, which in 2011 delivered the first 800Mbps (Megabits) capable network using ordinary flashing LED lights. Since then the kit has been improved to achieve a transmission rate of 1Gbps per single light frequency (basic LED’s usually use up to three light frequencies) and the operating bandwidth has been pushed to 180MHz from 30MHz before.
