System demonstration for visible light communication using adaptive threshold detection for low data rate applications

With the materialization of light emitting devices for solid state lighting, visible light communication (VLC) has provided a prospect to realize low cost, high speed, power efficient and secure data transmission in addition to lighting. Incandescent and fluorescent light sources are being replaced by light emitting diodes (LED) which are not only energy efficient but also help in reducing carbon dioxide CO 2 emission. In this paper, experimental results are being presented using a new protocol for VLC and the optimum placement of the LEDs within the transmitter to maximize the transmitter foot prints.
