Lifi wireless communication
This project tried to show a basic prototype of wireless data transmission using LiFi and what future it holds within itself for the new generation needs.
Abstract
Li-Fi stands for Light-fidelity. The technology was very new and proposed by the German Physicist Harald Hass in 2011. Li-Fi basically aims to replace Wi-Fi by using light to transmit internet signals. It works on the principle of visible light communication I.e .use of visible light for communication. Though Li-Fi is a system that is capable of transmitting data at high speeds over the visible light, ultraviolet and infrared spectrum but in its present state only LED lambs can be used. It consists of a light bulb which is used as an emitter and a photo diode as a receiver. Li-Fi provides transmission of data through an LED light bulb that varies in intensity faster than human eye can follow .It is ideal for high density wireless data coverage in confined area where there is no obstacle. It provides better bandwidth efficiency, availability& security than wifi. The technology is actively being developed by several organizations across the globe. In this project we tried to show a basic prototype of wireless data transmission using LiFi and what future it holds within itself for the new generation needs
