Tuneable and portable lighting system for Visible Light Communications (TP-VLC)

This work presents a low cost prototype implementing new IEEE 802.15.7 standard for Visible Light Communications. A commercial off-the-shelf development platform is used to implement the firmware controlling the system. The system is tested with different LED luminaires and distances achieving data rates of 100 kbit/s with Bit Error Rates between (10 −7 to 10 −4 ) over distances up to 8 meters. Brightness control of the LED while transmitting data can be achieved allowing for a tuneable VLC system.
