Abstract
With the widespread of light emitting diodes (LEDs)
as a primary source of illumination, visible light communication
(VLC) offers a lot of potentials by providing both resources
and energy saving advantages. This paper presents a practical
implementation of an integration of Power Line Communication
(PLC) and VLC. The system uses spread frequency shift keying
(S-FSK) and on-off keying (OOK) in the PLC and VLC channel
respectively. The system is of low complexity, low cost and dedicated
to enhance low data rate application of PLC technology.
The practical design is compatible with the European Committee
for Electrotechnical Standardization (CENELEC) band A and
the test are done on a Chinese home environment where the
Electric Power Research Institute (EPRI) specifies a 3 kHz to
500 kHz band. Results illustrating the effect of sunlight on this
system are presented.
