CONCLUSIONS
In this article we have recapitulated recent developments
in the area of high-speed visible-light
communication. These systems exploit the natural
opportunity of piggybacking data transmission
over new LED-based luminaires. Our focus was
on demonstrating the maturity of this technology
for a number of dense high-speed wireless communication
scenarios envisioned mainly in indoor
settings such as aircraft cabins, operating theatres,
trade fair halls, or private homes.
We have summarized recent experimental
work demonstrating that VLC has high potential
for high-speed communications in these scenarios.
Even today, the simplest on-off keying modulation
enables more than 100 Mb/s, while
transmission speed can be further increased
beyond 1 Gb/s by using more spectrally efficient
adaptive wideband modulation techniques and
wavelength-division multiplexing.
