    Abstract: A mobile device can identify its physical location without explicit knowledge of physical coordinates, but instead using sensor measurements dependence on distance, e.g., signal strength from a Wi-Fi router. Sensor measurements can be used to determine the mobile device is at a same physical location as a previous measurement. For example, numerous measurements of sensor values can form data points that are clustered in sensor space, where a cluster of data points in sensor space corresponds to a physical cluster of physical positions in physical space. A current physical location of the mobile device can be determined by identifying which cluster of sensor positions the current measurements correspond. To identify the cluster of sensor positions, a probability can be determined for each cluster based on a sensor distance between the current measurement and a representative data point of the cluster and a kernel function.

    Abstract translation: 移动设备可以在不明确物理坐标的情况下识别其物理位置，而是使用依赖于距离（例如，来自Wi-Fi路由器的信号强度）的传感器测量。 传感器测量可用于确定移动设备与之前的测量处于相同的物理位置。 例如，传感器值的大量测量可形成聚集在传感器空间中的数据点，其中传感器空间中的数据点群对应于物理空间中的物理位置的物理群集。 移动设备的当前物理位置可以通过识别当前测量值对应于哪个传感器位置簇来确定。 为了识别传感器位置的集群，可以基于当前测量与集群的代表性数据点和核函数之间的传感器距离来确定每个集群的概率。

    Abstract: A mobile device can include ranging circuitry to determine distance to another mobile device. A first wireless protocol can establish an initial communication session to perform authentication and/or exchange ranging settings. A second protocol can perform ranging, and other wireless protocols can transmit content. In one example, the distance information can be used to display a relative position of another device on a user interface of a sending device. The user interface can allow a user to quickly and accurately select the recipient device for sending the data item. As other example, the distance information obtained from ranging can be used to trigger a notification (e.g., a reminder) to be output from a first mobile device or used to display a visual indicator on a receiving device. Proximity of a device (e.g., as determined by a distance) can be used to suggest recipient for a new communication.
