Li-Fi technology and its applications

Abstract

Li-Fi (Light fidelity) refers to visible light communication systems using light emitting diodes and provides highspeed internet. Now a days internet became a major demand, Li-Fi has more capability in terms of bandwidth in visible region. Li-Fi is hundred times greater speed than Wi-Fi and provides security. Light fidelity deals with optical wireless communication which is emerging technology the basic idea behind this technology is the data can be sent through LED light whose strength varies even faster than Wi-Fi. This technology comes to be 10 times low-cost than the Wi-Fi and much safer Li-fi technology can be used in light bulbs in cars, light lamps, street lights, flashlight of mobile and any other light source are providing you internet access at very high-speed. The main advantage of Li-Fi Technology is internet at high-speed and security.It can also be used in various fields Such as in Military for security purposed in hospitals medical instruments, in Air planes to prevent radio signals, Power plants, Under water communication, Multi user communication, Prevention of accidents of vehicles, in tracing the place etc. We expect a future where data for laptops, smarts phones and tablets is transmitted through the light only with security.
