                                                        ABSTRACT: 
	This paper develops a prototype to demonstrate a
full-duplex wireless visible light communication (VLC) system based on Universal
Serial Bus (USB) port. Combing with a USB 2.0 port on one
board, it can achieve up to 2 Mbps bit rates error free, which is mainly limited to the USB bridge
circuit, between two computers for data transmission, such as text, audio and video.
Hyper Terminal and self-written software are used to allow setting the
transmission data rate, control bits, check bits and achieve real-time
transmission between any two mobile devices with a USB port. The work is based on
the research of VLC local access network. This paper also shows the experimental
results and the relationship between system transmission eye diagram and bit
rate.
