Moreover, VLC presents a unique feature in
short-range underwater transmission where light
sources in the blue-green spectral window are
convenient. The reach is, of course, limited by
the clarity and attenuation of the water, but the
lack of alternatives for high-speed wireless underwater
communication underscores the potential
of VLC for resource exploration and yield as well
as for data exchange between divers or between
robots and submarine docking stations.
