LiFi technology

What is LiFi ?

LiFi is a wireless optical networking technology that uses light emitting diodes (LEDs) 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 chip that modulates the light imperceptibly for optical data transmission . LiFi data is transmitted by the LED bulbs and received by photoreceptors.


LiFi early developmental models were capable of 150 Mbps. Some commercial kits enabling that speed have been released . In the lab with stronger LEDs and different technology , researchers have enabled 10 gigabits per second which is faster than 802.11ad.
