Light-Fidelity (LiFi) is quickly emerging as the next-generation communication technology thanks to its unique benefits, such as available spectrum, high data rates, low implementation costs, and inherent beamforming capabilities. As a consequence, it is endorsed by the scientific literature as an appealing innovation for disclosing disruptive services. The wavefront of LiFi technology is very wide: in this manuscript, we focus our attention on the interplay with the Internet of Things. Essentially, LiFi can assist the IoT in interconnecting a massive number of heterogeneous devices by addressing the current Radio Frequency spectrum bottleneck. Moreover, by investigating LiFi and IoT individually, several surveys and review papers testify to the noteworthiness of both technologies. However, to the best of the authors’ knowledge, a comprehensive investigation of contributions where both of them interplay is missing. To fill this gap, this survey provides a thorough investigation of all the research areas in which LiFi key features might enhance the upcoming IoT networks. The evaluation of existing literature on LiFi adopted in the IoT domain can be valuable in identifying missing gaps arising from the interaction of these two technologies, as well as proficiently pinpointing future research directions.

光保真 (LiFi) 凭借其独特的优势，如可用频谱、高数据速率、低实施成本和固有的波束成形功能，正迅速成为下一代通信技术。因此，它被科学文献认可为披露破坏性服务的有吸引​​力的创新。LiFi 技术的波前非常广泛：在这份手稿中，我们将注意力集中在与物联网的相互作用上。从本质上讲，LiFi 可以通过解决当前的无线电频谱瓶颈来帮助物联网互连大量异构设备。此外，通过单独调查 LiFi 和物联网，一些调查和评论论文证明了这两种技术的重要性。然而，据作者所知，对两者相互作用缺失的贡献进行全面调查。为了填补这一空白，本次调查对 LiFi 关键功能可能增强即将到来的物联网网络的所有研究领域进行了彻底调查。对物联网领域中采用的 LiFi 现有文献的评估对于确定这两种技术相互作用所产生的缺失差距以及熟练地确定未来的研究方向非常有价值。
