DATA TRANSFIRMATION THROUGH VISIBLE LIGHT COMMUNICATION (VLC) /LI-FI USING WIRELESS COMMUNICATION TECHNOLOGY

Abstract

The Radio Frequency (RF) communication suffers from high latency and interface issues.

Beside with it, a separate setup for transmission and reception of Radio Frequency (RF) waves is require for Radio Frequency communication (RF). In order to overcoming the said limitations, a preferred communication technique is required such as Visible Light Communication (VLC) which has higher bandwidth and immunity to interference from electromagnetic sources. The modernization in the field of solid-state lighting primes to the replacement of florescent lamps by Light Emitting Diodes (LEDs) which further encourages the usage of Visible Light Communication (VLC). This research work represents a survey of the potential architecture, applications, modulation techniques, standardization, and research challenges in visible light Communication (VLC). In this project we have developed an Arduino based visible light communication system which is often called Li-Fi. As opposed to traditional Wireless Fidelity (Wi-Fi) technology, Light Fidelity (Li-Fi) technology uses visible light spectrum to transmit data quickly and securely.
