Abstract

• A simple prototype of an optical wireless audio system by using laser diode as a source for the transmitter has been proposed. In this project, we designed and implemented a wireless optical transmitter and receiver system that established an audio communication at some distances with weak signal via visible light communication. The wavelength that used for this project is 635 nm which is visible wavelength range. Based on the experimental results, the visible light communication system can work successfully within in distance up to 30 meters. This project is successfully improved the transmission distance and signal coverage area effectively with low cost of hardware, high communication speed and almost no limit to bandwidth.
