    LiFi, a wireless optical networking technology, is designed to use LED light bulbs, very similar to those energy-conscious in homes and offices. Photoreceptors receive the transmitted data from the LED light bulbs fitted with a chip that modulates the light imperceptibly for optical data transmission.

    LiFi’s early developmental models were capable of 150 megabits-per-second (Mbps). Some commercial kits have increased that speed. In the lab, with stronger LEDs and different technology, researchers can equip 10 gigabits-per-second (Gbps), which is faster than 802.11ad.
