A Survey on Audio Communication for Location Information by Using Visible Light Communication

Abstract

Visible Light Communication (VLC) is a technology that may be consider as better option for 5G in wireless communicationsin the future. The technology may be used in many indoor applications. The specific presentation of VLC in this study is with the use of light emitting diodes (LEDs) as the medium for transmission. Digital information will be sent through the LEDs as light pulses, and then a receiver will be able to collect the light pulses as a code and translate it to a corresponding audio data.VLC has strengths in energy efficiencyand ultra wide bandwidth, but also has weakness in transmission range andobstacles in transmission paths.This paper gives idea about VLC and their working principle.
