With the invention of new Li-fi technology, you will soon find light bulbs of your car, light lamps in your room, lights in subway, flashlight of your mobile and any other light source are providing you internet access at very high speed.
Li-fi technology is the milestone in the history of information technology. You have got the idea that Li-Fi Technology is something light. Yes, Li-fi technology or light-fidelity technology transmits data wirelessly at high speeds with the use of light emitting diodes.
Working of Li-Fi Technology
The functioning of new Li-Fi technology is just simple. You will have a light source at one end like a LED and a photo detector (Light Sensor) on the other end. As soon as, LED starts glowing, photo detector or light sensor on other end will detect light and get a binary 1 otherwise binary 0.

How can data be transmit via this new Li-F- technology?
Flashing a LED certain times will build up a message to transmit. Flashing of light is detected by the photo detector or light sensor and it will receive a message.

Now, think of several LEDs with some different colors, flashing together and building a huge information to transmit. It is observed that green laser with the red laser can transmit data at 1 GBPS
