Visible Light Communication devices ready for commercialization
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. "The most obvious application for this system is guiding visitors in galleries and museums. "Positioning services using indoor GPS and wireless communication already exist. Using light from LEDs instead of radio signals also makes it possible to communicate in tunnels and factories, where radio reception can be difficult.
