Realtime audio streaming using visible light communication

With an increase in demand of high data rate near field communication, Visible Light Communication (VLC) has been recognized as advanced and most promising innovation to acknowledge short-run, high speed as well as large capacity wireless communication. In this paper, a prototype of real time embedded system has been proposed, using modest financially accessible light emitting diodes (LED), which can transmit audio wirelessly. Experimental results shows high quality real time audio can be transmitted and received at maximum range of 3 meters through appropriate format of LED sources and proper concentration of LED light on receiver. VLC system has been designed and implemented for high quality audio streaming.
