LiFi (Light Fidelity) is a communication technology through modulated LED light that enables data exchange between a specific LED lighting fixture and a computer, making Internet access possible. LiFi can work as a complement to WiFi or as a substitute where WiFi is not available or weakly deployed. Shuji Nakamura, who won the Nobel Prize for inventing the blue LED, sees LiFi as critical to the future of lighting technology as LED becomes commoditized and the industry seeks new value areas. While the basic concept has been recently commercialized for visible light communication enabling indoor positioning and some communications, true LiFi has not commercialized.
That appears to be changing. PureLifi, a company founded by Professor Harald Haas (one of the original developers of the technology), recently demonstrated its new LiFi-enabled luminaire at the Mobile World Congress in Barcelona. PureLiFi partnered with Lucibel to create a system enabling bidirectional broadband communication between luminaires and computing devices fitted with an appropriate USB key. The new luminaire is being manufactured by Lucibel in France.
