论文摘要
想象一下您的所有连接设备（计算机，电视，语音控制设备，打印机，安全摄像机等）的房屋地图。然后，您可以轻松地将设备分组到用户填充中，监视房屋不同区域中的Wi-Fi质量和活动，甚至在您的房屋中找到丢失的平板电脑。 Mapifi是一种生成家庭中设备映射的方法。 Mapifi的第一部分涉及用户（技术人员或居民）使用倾听Wi-Fi无线电频道的移动设备在房屋周围行走。移动设备检测到来自连接到网关并测量其信号强度的所有房屋设备的Wi-Fi数据包（忽略数据包的内容）。第二部分是一种算法，该算法使用所有信号强度测量值来估计家庭中所有设备的位置。然后，Mapifi将房屋的空间视为坐标系，其设备标记为该空间中的点。根据这项技术已提交专利。本文发表在SCTE技术期刊上（请参阅https://wagtail-prod-storage.s3.amazonaws.com/documents/scte_technical_journal_journal_v1n3.pdf）发表的论文。
Imagine a map of your home with all of your connected devices (computers, TVs, voice control devices, printers, security cameras, etc.), in their location. You could then easily group devices into user-profiles, monitor Wi-Fi quality and activity in different areas of your home, and even locate a lost tablet in your home. MapiFi is a method to generate that map of the devices in a home. The first part of MapiFi involves the user (either a technician or the resident) walking around the home with a mobile device that listens to Wi-Fi radio channels. The mobile device detects Wi-Fi packets that come from all of the home's devices that connect to the gateway and measures their signal strengths (ignoring the content of the packets). The second part is an algorithm that uses all the signal-strength measurements to estimate the locations of all the devices in the home. Then, MapiFi visualizes the home's space as a coordinate system with devices marked as points in this space. A patent has been filed based on this technology.
