本文研究了一种射频与可见光通信（VLC）混合系统。设计并分析了一个由多个VLC接入点和RF接入点组成的混合系统。在室内环境中，VLC ap提供非常高的数据速率，同时证明了照明，而RF ap以中等数据速率提供无处不在的覆盖。由于VLC网络依赖于现有的照明基础设施，尽管在某些地区支持非常高的数据速率，但它们可能并不总是能够提供完全覆盖。因此，在实际部署中，应该增加独立的VLC网络，以提高每个用户数据速率的覆盖率。在这种情况下，射频接入点可用于提高VLC网络的每用户速率覆盖范围，并提供无处不在的控制功能。为了提高独立VLC网络的每用户中断数据速率性能，本文提出了一种简单的射频部署方法。假设VLC系统资源是固定的，量化射频系统的最小频谱和功率需求，引入VLC系统后，混合射频/VLC系统达到一定的每用户速率覆盖性能。
In this paper, a hybrid radio frequency (RF) and visible light communication (VLC) system is considered. A hybrid system with multiple VLC access points (APs) and RF APs is designed and analyzed. In indoor environments, VLC APs provide very high data rates whilst proving illumination, and RF APs offer ubiquitous coverage with moderate data rates. Since VLC networks piggyback on existing lighting infrastructures, they may not always be able to provide full coverage despite supporting very high data rates in some areas. Hence in practical deployments, the standalone VLC networks should be augmented in order to improve the per user data rate coverage. In this context, RF APs can be used to improve the per user rate coverage of VLC networks as well as to provide the ubiquitous control functionalities. In this paper, a simple RF deployment is proposed in order to improve the per user outage data rate performance of standalone VLC networks. It is assumed that the VLC system resources are fixed, and this paper quantifies the minimum spectrum and power requirements for a RF system, which after introduction to the VLC system, the hybrid RF/VLC system achieves certain per user rate coverage performances.
