Design and demonstration of room division multiplexing-based hybrid VLC network

A room division multiplexing(RDM)-based hybrid visible light communication(VLC) network for realizing indoor broadband communication within a multi-room house is presented.The downlink information is transmitted by light-emitting diode lamps,whereas the uplink information is transmitted through WiFi.RDM is introduced to improve the VLC network throughput;in addition,the associated signaling localization and active handoff mechanisms are designed for implementation.The experimental platform demonstrates the effectiveness of the proposed hybrid architecture,along with the RDM and active handoff mechanisms.
