When LED bulbs Becomes a Medium of Communication: Li-Fi Technology

Abstract

In recent era, the use of internet is been increasing day by day. Internet has become more of a primary need than a secondary need. In recent time, Wi-Fi came into existence and life of the people by using internet got easier. But as said, every coin has two sides; Wi-Fi comes with many disadvantages like as the number of users increases for using the Wi-Fi system, the speed of the device decreases. Another disadvantage which being noticed from last few years are the ill-effects Wi-Fi causes to human health. And as every limitation has a way to new innovations. These limitation of Wi-Fi technology is being overcome by a new technology called Li-Fi (Light Fidelity) invented by Professor Harald Haas who proposes these concept as Li-Fi is a wireless optical networking technology that uses light –emitting diodes(LED’s) for data transmission. It uses same concepts that are used in infrared.
