摘要
针对可见光通信研究主要集中在元件设计、物理层通信等领域,对可见光室内组网的系统规划和设计研究较少这一特点,阐述了可见光通信的技术特点和典型组网架构,结合当前无线通信系统的演进和发展趋势,提出了多小区分层覆盖、控制面与用户面分离、分布式与主从式并存的可见光室内组网策略,并对可见光室内通信系统的光源布局、网络切换、接入控制等关键技术进行了研究和分析。
The correlation studies mainly focus on the fields of elements design, physical layer communication, system planning and design on VLC network have not obtained enough attention yet. Therefore, the technical features of VLC and the typical network architecture were discussed, according to the evolution and development trend of the wireless communication system, some networking strategies for the indoor visible light networking were proposed, such as hierarchical cell coverage, control plane and user plane separation, distributed model and client-server model coexist in strategy. The key technologies of VLC system about the layout of lighting, network handover and access control were analyzed.
