The future of industrial location-aided applications is shaped by the ubiquity of Internet-of-Things (IoT) devices. As an increasing amount of commercial off-the-shelf radio devices support channel response collection, it is possible to achieve fine-grained position estimation at a relatively low cost. In this article, we focus on channel response-based positioning and tracking for industrial IoT applications. We first give an overview of the state of the art (SOTA) of channel response-enabled localization, which is further classified into two categories, \textit{i.e.}, device-based and contact-free schemes. Then we propose a taxonomy for these complementary approaches concerning the involved techniques. Finally, we discuss the practical issues of the SOTA methods for real-world applications and point out future research opportunities for channel response-based positioning and tracking.

工业物联网无处不在的室内定位和跟踪：通道响应视角

无处不在的物联网 (IoT) 设备塑造了工业定位辅助应用的未来。随着越来越多的商用现成无线电设备支持信道响应收集，可以以相对较低的成本实现细粒度的位置估计。在本文中，我们重点关注工业物联网应用中基于通道响应的定位和跟踪。我们首先概述了启用通道响应的本地化的最新技术（SOTA），它进一步分为两类，\textit{ie}，基于设备和无接触方案。然后，我们为这些关于所涉及技术的互补方法提出了一个分类法。最后，
