Smartphones perform Wifi scans to adapt to the changing wireless environments causes by mobility. From network monitoring perspective, such scans provide a natural stream of network measurements from client's point of view. In order to see whether such measurements can provide new insights in monitoring large scale wireless networks, we collected the Wifi scan results data, together with other Wifi related logs, from the PhoneLab smartphone testbed over 5 months. All data are collected passively from the smartphones. ; [e-mail]智能手机会执行Wi-Fi扫描 (Wifi)，以适配因移动性引发的无线环境变化。从网络监测视角来看，此类扫描能够提供源自客户端视角的自然网络测量数据流。为探究此类测量能否为大规模无线网络监测提供全新研究视角，我们在5个多月的时间内，从PhoneLab智能手机试验床中采集了Wi-Fi扫描结果数据及其他相关Wi-Fi日志。所有数据均从智能手机中被动采集得到。[e-mail]
