HENCE ALL THAT US REQUIRED IS SOME LED’S AND CONTROLLER THAT CODES DATA INTO THOSE LED’S .WE HAVE TO JUST VARY THE RATE AT WHICH THE LED’S FLICKER DEPENDING UPON DATA WE WANT TO ENCODE

THUS EVERY LIGHT SOURCE WILL WORK AS A HUB FOR TRANSMISSIONLOOOOOOOOOOOOOO.jpg

ADVANTAGE OF LI-FI TECHNOLOGY

IT IS POSSIBLE TO ACHIEVE MORE THAN THAN 10 Gbps,

THEORETICALLY ALLOWING A HIGH DEFINITION  FILM TO BE DOWNLOAD IN 30 SEC.

TRANSMISSION OF DATA IS FAST AND EASY.

ITS MAIN ADVANTAGE IS ITS BANDWIDTH IS 10,000
