Data Transmission Using Visible Light Communication Technology through Mobile Phone LED

Abstract

Due to the growing number of applications and devices that need wireless access to the Internet, the airwaves are becoming confined. This problem makes it more and more difficult to get a reliable and high speed access. The unique physical properties of light promise to deliver a very high-speed network connections resulting in orders of magnitude improved user data rates. This study provides a new communication system for transmission of data between mobile phones and computers using Visible Light Communication (VLC) technology through the LED of mobile phones. The LED transmits the light to a light Sensor, which is a part of a complete receiver system. The system consists of two parts, the transmitter, which is comprised of mobile programmed to modulate and Guide the data to the phone's LED. The second part is a receiver system consists of a light sensor to receive and recover the original data and stores data on computer.
