近年来，无线通信的功能已不仅仅局限于用户之间的通信，还扩展到传感应用。事实上，几种基于 WLAN 的传感技术已经开发出来，这些技术依赖于室内环境中的信道状态信息 (CSI) 导出的多径无线电传播的变化。在本文中，我们提出了一种基于 WLAN 的室外人体检测系统，这是第一个基于 IEEE 802.11ac WLAN CSI 的室外传感尝试。室外环境中的多径数量有限，因此感知变得困难。为了实现室外 CSI 传感，我们提出了一种基于 IEEE 802.11ac WLAN 的传感系统。具体来说，本文试图回答这个问题：“我们如何安装发射器-接收器对？”基于对实验结果的分析。此外，我们还提供有关 WLAN 传感设备最佳安装的公开讨论。
In recent years, the functionality of wireless communications has not only been limited to communication between users, but has also been extended to sensing applications. In fact, several WLAN-based sensing technologies, which rely on changes in multipath radio propagation derived from a channel state information (CSI) in indoor environments, have already been developed. In this paper, we present a WLAN-based outdoor human detection system – the first in IEEE 802.11ac WLAN CSI-based outdoor sensing attempts. The number of multipaths in an outdoor environment is limited, thus, making sensing difficult. To realize outdoor CSI sensing, we present an IEEE 802.11ac WLAN-based sensing system. Specifically, this paper tries to answer the question, "How do we install a transmitter-receiver pair?" based on an analysis of the experimental results. Moreover, we provide open discussions regarding the optimum installation of WLAN sensing devices.
