We present the feasibility of visible light information broadcasting system based on message signboard. This system can provide the bit error rates (BERs) lower than 10−6 at 4-Mbps and 10-Mbps data rate. Using four LED array modules, 4-Mbps visible light signals could be transmitted over 4.2 m. In case of 10-Mbps data rate, the maximum transmission distance was 3.6 m.
