Today, the Bluetooth transceiver is integrated into almost all modern mobile devices. Although it can transmit audio signals, it is unable to transmit video signals. But VLC can. With advances in visible light communication (VLC) research, it is likely that one day mobile equipments would include the visible-light transceiver for wireless optical access to the Internet and visual and audio information. An audio/video (A/V) transceiver and a data transceiver that can connect to Android platforms are presented here. Real-time video and pulse-position modulated stereo audio signals are transmitted by a white LED over free space. For file exchanges, a USB Android host IC FT311D is used to bridge smartphones to any external VLC UART peripheral.
