“Outstanding Technology has developed two commercial products using visible light communication technology, using LED lights to transmit data. These are a location service for smartphones, called the Commulight System, and a visible light transceiver, the TR01.
The Commulight System consists of a receiver that plugs into a smartphone or tablet, and LED lights with a built-in transmitter. The receiving device obtains IDs emitted by the LED lights, enabling it to download content relevant to the user’s location. The receiver is available in two types, one that connects via USB, and one that connects via the headphone jack.”
