LiFi的未来部署将包括灯具阵列。我们试图探索多个用户之间的交互，设备的移动性，设备方向和用户流量。我们描述了一个新的多电池照明测试台，旨在研究和优化密集的LiFi系统。该测试平台由15个商用LED灯组成，这些灯由定制LiFi驱动器和16通道软件定义无线电驱动。我们开发了一个模型的系统的移动性和不同的接收器方向的预测信号强度的目的。在试验台上收集的数据显示出良好的一致性模型。最后，我们展示了如何分析模型和测量数据可以用来研究基于RSS的VLP和VLC切换在多小区系统。
Future deployments of LiFi will incorporate arrays of luminaires. We seek to explore the interactions among multiple users, mobility of devices, device orientation, and user traffic. We describe a new multi-cell lighting testbed created to study and optimize dense LiFi systems. The testbed is constructed with 15 commercial LED lights that are driven by custom LiFi drivers and a 16-channel software defined radio. We develop a model for the system for the purpose of predicting signal strength under mobility and different receiver orientations. Data collected in the testbed show good conformance to the model. Lastly, we show how the analytical model and the measured data can be used to study RSS-based VLP and VLC handover in multi-cell systems.
