Abstract

With the massive technological advancements being made every year, the need for better and faster data rates, better and improved security measures is being given high importance in the research community. Therefore, open space communication has become a hot topic in the recent years of which Visible Light Communication (VLC), is one of the highly researched areas. The reason for its high popularity is because of its ability to provide high data rates, high bandwidth and a very secure medium of transmission as it cannot penetrate walls. This paper investigates the impact of visible light communication on audio and video transmissions. A real experimental test-bed is setup to test the performance of audio transmission over VLC under various conditions such as distance from the source, interfering lighting, etc. Subjectives tests are carried out to assess the quality of the audio VLC link as perceived by the user. Additionally, a comprehensive study on existing simultaneous video and audio transmission systems over VLC is provided and the challenges and remaining open issues are identified.
