An indoor wireless communication system using off-the-shelf components was presented. We adopted on-off keying to modulate LEDs and realized data transmission using RS-485 protocol with a DC-balanced coding with error check and correction abilities. The system can keep 10-7error rate within 2.5m reach at a rate of 115200 bps.
