传统上，Wi-Fi无线电信号被广泛用于无线局域网（WLAN）中的数据传输。最近，也应用Wi-Fi无线电信号来感测这些信号传播的环境并识别与某些活动相关联的变化一直是一个有趣的话题。这种技术被称为Wi-Fi传感，它已被证明在各种用例中是有效的，例如接近检测，手势识别，目标计数和健康监控。因此，IEEE 802.11工作组已经形成了新的任务组802.11 bf，以开发新的修正案来定义必要的PHY和MAC协议，以支持所有频谱带中的Wi-Fi感测，包括亚7 GHz频带（2.4 GHz、5 GHz和6 GHz频带）以及60 GHz毫米波频带。在本文中，我们的主要目标是识别和描述IEEE 802.11 bf中开发的基本元素，以在不同的WLAN场景中实现Wi-Fi传感应用。
Conventionally, Wi-Fi radio signals are widely used for data transmissions in a wireless local area network (WLAN). Recently, it has been an interesting topic to also apply Wi-Fi radio signals to sense the environment where these signals propagate and identify changes associated with certain activities. This technique is referred to as Wi-Fi sensing, and it has been proven effective in a variety of use cases, such as proximity detection, gesture recognition, target counting, and health monitoring. As a result, the IEEE 802.11 working group has formed a new Task Group, 802.11 bf, to develop a new amendment to define necessary PHY and MAC protocols to support Wi-Fi sensing in all spectrum bands, including sub-7 GHz bands (2.4 GHz, 5 GHz, and 6 GHz band), as well as 60 GHz millimeter-wave band. In this article, our primary goal is to identify and describe the basic elements that have been developed in IEEE 802.11 bf to enable Wi-Fi sensing applications in different WLAN scenarios.
