Query: Challenges and potentials for visible light communications: State of the
  art   Visible Light Communication is the emerging field in the area of Indoor
Optical Wireless Communication which uses white light LEDs for transmitting
data and light simultaneously. LEDs can be modulated at very high speeds which
increases its efficiency and enabling it for the dual purposes of data
communication and illumination simultaneously. Radio Frequency have some
limitations which is not at par with the current demand of bandwidth but using
visible light, it is possible to achieve higher data rates per user. In this
paper, we discuss some challenges, potentials and possible future applications
for this new technology. Basically, visible light communication is for indoor
application capable of multiuser access. We also design a very basic
illumination pattern inside a room using uniform power distribution.
