摘要
移动通信网络发展迅速,移动宽带用户以及新兴信息业务与日俱增,可见光通信(VLC)成为室内异构组网的重要补充手段之一,其相关技术亟待突破。首先,围绕研究背景与意义进行简要概述,其次,深入讨论并分析了室内可见光通信异构组网架构设计、垂直切换方案设计和多用户接入机制优化三个关键技术的主要进展。最后,从实际应用需求角度出发,对三者进行总结与展望。
With the rapid development of mobile communication network,mobile broadband users and emerging information services are increasing day by day.Visible light communication(VLC)has become one of the important supplementary means of indoor heterogeneous networking,and its related technologies need to be broken through ur-gently.Firstly,the research background and significance are briefly summarized,and secondly,the main progress of three key technologies:indoor visible light communication heterogeneous networking architecture design,vertical switching scheme design and multi-user access mechanism optimization is discussed and analyzed in depth.Finally,from the perspective of practical application demand,the three are summarized and prospected.
