Visible light communication (VLC) generally called "LIFI" using the light-emitting diode (LED) will become an appealing alternative to the radio frequency communication technology for indoor wireless broadband broadcasting. However, the LED lamps should access to the backbone information network and this requirement is not easily satisfied.
Power line communication (PLC) systems utilize the ubiquitous power line network to power the LED lamps while serving as the backbone network for the VLC systems naturally. we propose a cost-effective indoor broadband broadcasting system based on the deep integration of PLC and VLC. The proposed scheme significantly reduces the complexity of the VLC network protocol, and requires much less modification to the current infrastructure, while providing better signal coverage.
