Abstract: Power Line Communication (PLC) is a technology that employs the infrastructure of electrical power distribution system as communication medium. PLC technology could provide the consumer with a spectrum of services such as Internet, home entertainment and home automation. Dealing with very high voltages and its isolation is a problem of PLC. A solution to this problem is proposed by combining Power Line Communication and Visible Light Communication. Visible Light Communication is a mode of communication which uses visible light as transmission medium. ASK modulated signal is used to control the switching of LED bulbs which are connected to the same power line. This serves the dual purpose of lighting and transmitter of Visible Light Communication. This light is allowed to fall on photodiodes and the output of photodiodes is used to recreate the original signal. This system has numerous advantages. Since it doesn’t use radio frequencies it can be implemented in RF sensitive environments such as hospitals, airplanes etc. The extra cost required in the infrastructure development is comparatively less.
