Design and Development of the Visible Light Communication System

摘要

This paper presents the development of a Visible Light Communications (VLC) system for a local area network (LAN) based on the IEEE 802.15.7 standard. The proposed VLC system enables new indoor applications by providing simultaneous illumination and networking capability between the optical wireless devices. The VLC system uses an AVAGO Technologies HSDL-4230 LED as the transmitter and an OSRAM SFH203FA photodiode as the receiver. The distance in which the optical link was measured was up to 1 meter and achieved about 9.2 Mb/s throughput. Therefore, it is suitable for most of the applications for the home or office environment such as Internet communication, multimedia streaming, etc.
