可见光通信（VLC）能够满足室内场景中不断增长的数据速率需求。照明基础设施还可以在无线局域网（WLAN）的下行链路中使用，其中发光二极管用于传输信息。VLC接入点（ap）的回程构成了wlan的潜在瓶颈，特别是在ap数量很高的大型房间中。因此，提出了一种替代的基于反射的协作无线系统概念，其中不需要有线连接来连接ap。然后，根据得到的信噪比对其数据速率进行分析。结果表明，所提出的无线协同系统的性能与传统有线回程的性能非常接近。最后，我们使用Jain公平性指数证明了该方案为所有用户提供了公平的覆盖质量。
Visible light communication (VLC) is capable of satisfying the escalating data rate demand in indoor scenarios. The lighting infrastructure may also be exploited in the downlink of a wireless local area network (WLAN), where light-emitting diodes are used for transmitting information. The backhaul of VLC access points (APs) constitutes a potential bottleneck in WLANs, especially in large rooms where the number of APs is high. Thus, an alternative reflection-based cooperative wireless system concept is proposed, where no wired connections are required for connecting the APs. Then, its data rate analysis is developed based on the signal-to-noise ratio attained. The results show that the performance of the cooperative wireless system advocated closely approximates the performance of the traditional wired backhaul. Finally, we demonstrate by using Jain’s index of fairness that the proposed scheme provides fair coverage quality for all users.
