After short-range IrDA links were replaced
by Bluetooth, optical wireless became a niche
market, and substantial acceptance has not yet
been reached in the industry. We believe that
the mass market opportunities for VLC will be
drastically increased when the lighting industry
agrees on the incorporation of data transmission
features into common lighting. Standardization
needs equally to move forward from point-topoint
link design issues to address multipoint-tomultipointtomultipoint
functionality. Finally, energy efficiency
aspects will certainly play a major role, in particular
for the implementation of VLC in mobile
devices.
