DATA TRANSMISSION USING VISIBLELIGHT COMMUNICATION.

Due to the enormous traffic in the radio frequency spectrum, there is a need for an alternative means for wireless communication which can accommodate increasing traffic demand. Visible light communication (VLC) is one such alternative which can provide high information transmission, using light from LEDs as the communication medium. In these systems, light-emitting diodes blinks when information is transmitted through them, a sensitive photovoltaic-cell can detect the on-off behavior and decode the information embedded in it. In this project analyses is done on various issues with current wireless communication systems, and discuss how visible light communications can resolve these issues. Later, the implementation process of the visible light communication system along with its design is described in detail. Thus achieved results of the system, in terms of transmission distance and type of data is discussed.
