Forget Lighting, This Li-Fi Is for Outdoor Data Communications Only

Germany’s Fraunhofer Heinrich Hertz Institute (HHI) has turned the concept of lighting on its head, developing a Li-Fi transmission box called the LED Backhaul in which the light waves have nothing to do with illumination, but everything to do with data communications. Fraunhofer HHI was so uninterested in illumination with its new optical transmitter that it decided to use infrared light, which, as part of the non-visible spectrum, is useless for general illumination. But the Berlin-based group deemed the technology as a handy and affordable way for slinging data back and forth between outdoor facilities up to 200 m apart, and is positioning it as a part of future 5G communication schemes. It has teamed with Japanese telecommunications company Sangikyo. http://www.ledsmagazine.com/
