Integrated Design of Low Complexity RSS Based Visible Light Indoor Positioning and Power-Line Communication System for Smart Hospitals

Future healthcare systems require smart hospitals with system-wide wireless communications and positioning functions, which cannot be facilitated by existing radio-frequency (RF) technologies. We present an integrated design of a novel low-complexity received signal strength (RSS) based hybrid visible light communication (VLC) and positioning (VLP) system. This tracking system consists of host optical transceivers embedded in existing light-emitting diode (LED) bulbs and user-end optical tags, which interface with the existing power wiring in a building. This hybrid VLC/PLC tracking system was validated by simulation and experiment. This VLC tracking system will enable smart hospital operations to modernize next-generation intelligent healthcare systems.

未来的医疗保健系统需要具备全系统无线通信和定位功能的智能医院，而现有的射频（RF）技术无法实现这一点。我们提出了一种基于接收信号强度（RSS）的新型低复杂度混合可见光通信（VLC）和定位（VLP）系统的集成设计。该跟踪系统由嵌入现有发光二极管（LED）灯泡的主机光收发器和用户端光标签组成，它们与建筑物中现有的电力线路连接。这种混合VLC/PLC跟踪系统通过仿真和实验得到了验证。这种VLC跟踪系统将使智能医院的运营能够实现下一代智能医疗保健系统的现代化。
