Eco Friendly Video Transmission through Visible Light Communication Using Lighting Control Network

Abstract

The communication by radio frequency signals has a drawback of less bandwidth and narrow spectrum.  This leads to the introduction of Li-Fi.  There is a rapid development in the solid state light emitting diode (LED) materials which gave a way for the next generation data communication known as visible light communication (VLC).  VLC has a promising future and it acts as a complement to the present RF communication by achieving larger bandwidth and high data rate.  At present, the day to day activities is done with lot of LED based lights, which can also be used for communication like fast switching, high power efficiency and safe to human vision.  Hence, this project presents about eco-friendly data communication through visible light which consists of the white LEDs that transmit video signals to the receiver.  The receiver circuit consists of solar panel connected with the amplifier and speakers to recover back the amplified version of original input signal. Here, we can transmit the video files from transmitter to the receiver using the LED where the video signal is digitized and transmitted. The transmitted signal is received by the photo-detector placed in the receiver.
