Visible light communication systems for optical video transmission

Abstract

This article describes an optical wireless system based on visible light communication (VLC), which allows a video broadcasting to reach a bit rate of 1 Mbps, although this system can also be used follow-speed sensor interconnections. The main advantages of this technology are the robustness against EM interference safety for human eye, and security against undesired network access. In this article. we present the electronic structure of a low-cost VLC transceiver, the modulation process and the Ethernet interface that has been implemented in each AP (access point). Finally. some conclusions are drawn. (C) 2010 Wiley Periodicals, Inc. Microwave Opt Technol Lett 52: 1572-1576, 2010; Published online in Wiley InterScience (www.interscience.wiley.com).
