DATA TRANSMISSION USING VISIBLE LIGHT COMMUNICATION

Abstract

Visible 
Light 
Communication 
technology is a wireless communication system 
that utilizes visible light spectrum to transmit 
data with high speed and secure manner 
compared to the traditional Wireless Fidelity 
(Wi-Fi) architecture. In this paper a smart 
phone is used in Li- Fi communication system. 
The aim of this proposed approach is to 
maximize the bit rate with high accuracy by 
using the flashlight of built-in smartphone 
camera as a source to send data and detect the 
effect of using a built-in smartphone ambient 
light sensor and external light detector sensors 
that is connected to Arduino NANO circuit to 
receive data. 
Four practical experiments were conducted to 
discover which light sensor accomplish higher 
data bit rate and tested the system performance 
under changing the distance between 
transmitter and receiver. The evaluation 
results demonstrated that the data bit rate is 
better with the proposed research than the 
others, where it reached more than 100bps 
with accuracy 100%.
