Visible Light Communications Consortium (VLCC) released their first Specification Standard adopting and expanding the IrDA Physical Layer to the newly released Visible Light Communication Consortium (VLCC) Specification Standard. The new specification standard from VLCC is the fruit of their current agreement through The Memorandum of Understanding between the two organizations signed on September 3rd, 2008.
The advantage of the VLCC system is an ability to transmit data by simply adding an optical communications device on the socket of the existing lighting fixtures, such as spot lights and incandescent lights, where light connections are already established. This feature provides digital data delivery system with minimum facility investment, and can potentially be used for broadcasting purposes at stations, hotels, public facilities, event halls or inside public transportation such as trains and buses.
This new specification of VLCC adapted IrDA transceiver transmission wavelength (IrDA physical layer) and expanded the spectrum to accommodate the visible light wavelength. By adapting IrDA specification, the existing IrDA optical modules can be used for VLCC data transmission with slight modification. Therefore, this specification will also contribute to the reduction of the development cost when IrDA specification is widely implemented in portable phones and printers.
VLCC will create an SIG (Special Interest Group) to further develop their work based on the MOU, to launch a new type of transceiver module which can be used for both IrDA and VLCC specifications on the market.
