Abstract
Previous research about low cost visible light communication (VLC) transceiver prototype was conducted which able to reach 98 cm, 70° and 19200 bps of transmitting distance, maximum transmission angle and transmission rate, respectively. The next prototype is built to get better performance by adding a reflector to the array phototransistor and split the power of the transceiver in order to maximize the light of the LED. This new prototype surpasses our target by reaching 134 cm of transmission distance. The system is also able to send digital multimedia files such as text, images, video in MPEG format and audio files in WAV and Mp3 format. The maximum bit rate of our prototype is 9600 bps and acceptance angle is 87°.
