Visible Light Communication: Information Broadcast System for Product Description

Abstract

Visible light communication (VLC) is a technology that delivers high-speed communication which is similar
to Wi-Fi. This method uses light as the medium for communication. This paper focuses on VLC, its applications, features
and comparison with existing technologies like Wi-Fi etc. Wireless communications has become an asset for the
communication process. Wi-Fi is of major use for general wireless coverage within buildings, whereas VLC can be used
for high density wireless data coverage in smaller areas. This technique is of great use in various applications in regions
where the main issue is radio interference. Hence both these technologies complement each other. Radio waves cannot
support high bandwidth because of reasons like compact spectrum availability and intrusion. VLC provides better
bandwidth, efficiency, connectivity and security than Wi-Fi. It provides speed greater than 1Gbps when tested under
laboratory conditions. By utilizing the low-cost nature of LEDs and lighting units to their maximum advantage, there are
lots of opportunities to exploit this medium. VLC is the transfer of data through light by taking fiber out of fiber optics
and sending data through LED light bulb. In this project we use light as a medium for communication and transfer of
data. LEDs are used at the transmitter end for collecting data with the help of Arduino and LDRs are used at the receiver
end along with PIC to display the data.
