物联网（IoT）是一个很有前途的范例，可以适应5G及以后的大规模设备连接。为了为未来的物联网铺平道路，频谱应该提前规划。频谱共享是物联网的一个较好的解决方案，因为可用的频谱资源是稀缺的。特别是，移动运营商倾向于利用当前蜂窝网络的现有标准和基础设施，并在许可的蜂窝频谱内部署物联网。然而，专有公司更喜欢在未经许可的频谱中部署物联网，以避免任何许可费用。在本文中，我们对在许可蜂窝频谱和非许可频谱中部署的流行物联网技术进行了调查。重点将放在频谱共享解决方案上，包括频谱共享、干扰模型和干扰管理。为此，我们讨论了不同物联网技术的优点和缺点。最后，我们确定了未来物联网面临的挑战，并提出了潜在的研究方向。
The Internet of Things (IoT) is a promising paradigm to accommodate massive device connections in 5G and beyond. To pave the way for future IoT, spectrum should be planned in advance. Spectrum sharing is a preferable solution for IoT due to the scarcity of available spectrum resources. In particular, mobile operators are inclined to exploit the existing standards and infrastructures of current cellular networks and deploy IoT within licensed cellular spectrum. However, proprietary companies prefer to deploy IoT within unlicensed spectrum to avoid any license fee. In this article, we provide a survey of prevalent IoT technologies deployed within licensed cellular spectrum and unlicensed spectrum. Emphasis will be on spectrum sharing solutions, including shared spectrum, interference model, and interference management. To this end, we discuss both advantages and disadvantages of different IoT technologies. Finally, we identify challenges for future IoT and suggest potential research directions.
