It is a wireless optical networking technology that uses light-emitting diodes (LED s) for data transmission.
Part of the Wireless technologies glossary: LiFi is a wireless optical networking technology that uses light-emitting diodes (LED s) for data transmission. LiFi is designed to use LED light bulbs similar to those currently in use in many energy-conscious homes and offices. However, LiFi bulbs are outfitted with a chip that modulates the light imperceptibly for optical data transmission. LiFi data is transmitted by the LED bulbs and received by photoreceptors. LiFi's early developmental models were capable of 150 megabits-per-second (Mbps). The term Li-Fi was coined by pureLiFi’s CSO, Professor Harald Haas, and refers to visible light communications (VLC) technology that delivers a high-speed, bidirectional networked, mobile communications in a similar manner as Wi-Fi.

Services via Light: The Lighting Industry and Li-Fi. pureLiFi, the home of LiFi, is recognised as the leader in the field – the use of the visible light spectrum instead of radio frequencies to enable wireless data communication. VLC is a category of Optical Wireless Communications (OWC). OWC includes infra-red and ultra-violet communications as well as visible light. However, VLC is unique in that the same visible light energy used for illumination may also be used for communication. What is LiFi? Prof. Harald Haas coined the term LiFi at his TED Global talk to describe the high speed, bidirectional, networked and mobile wireless communication of data using light. This is what he envisioned.....
