WiFi设备的普及和无处不在的WiFi网络覆盖为我们提供了将WiFi功能扩展到通信之外的机会，特别是在感知物理环境方面。在这篇文章中，我们调查了过去十年中利用商品设备的WiFi传感系统的演变。它将WiFi传感系统分为三大类：1)活动识别（大规模和小规模）；2)目标感知；3)本地化。我们在每个类别中突出了里程碑式的工作，并强调了他们采用的技术。接下来，本工作提出了现有WiFi传感系统面临的挑战。最后，全面讨论了商用WiFi传感的未来发展趋势。
The prevalence of WiFi devices and ubiquitous coverage of WiFi networks provide us the opportunity to extend WiFi capabilities beyond communication, particularly in sensing the physical environment. In this article, we survey the evolution of WiFi sensing systems utilizing commodity devices over the past decade. It groups WiFi sensing systems into three main categories: 1) activity recognition (large scale and small scale); 2) object sensing; and 3) localization. We highlight the milestone work in each category and the underline techniques they adopted. Next, this work presents the challenges faced by existing WiFi sensing systems. Finally, we comprehensively discuss the future trending of commodity WiFi sensing.
