Visible Light Communications (VLC) are gaining popularity and may provide an alternative means of communications in indoor settings. However, to date, there is very little research on the deployment or higher layer protocol design for VLC. In this paper, the authors first perform channel measurements using a physical layer testbed in the visible light band to understand its physical layer characteristics. Their measurements suggest that in order to increase data rates with VLC the beam width of a communicating link can be shrunk, and the transmission beam can be tuned to point towards the target recipient. They then perform Matlab simulations to verify that the human eye is able to accommodate the changes brought by shrinking a beam or by tuning the beam direction appropriately.
