Li-fi is a technology for a wireless communications between devices using light to transmit data..
LI-fi means light fideility..
The term was first introduced by harald haas during a 2011 Tedglobal talk in edinburgh. Li-fi will deliver internet at high speed with more security.
In li-fi technology we will use light bulb.
Light will flicker according to binary data received with a very fast speed.
In this technology we will use lamp driver. Lamp driver will receive data from server,according to data received light driver will instruct light device. Light device will start flickering according data reived from light driver.
Here, data is fed into an led light bulb(with signal processing technology), then it sends it sends data(embedded in its beam) at rapid speeds to the photo detector.
The tiny changes in the rapid dimming of led bulbs is then converted by the receiver into electrical signal. The signal is then converted back into a binary data stream that the user would recognize as web, video or audio format.
