    • Methods, program products, and systems for reducing a location search space are described. A mobile device, when arriving at a venue, can determine a location of the mobile device using signals from one or more signal sources associated with the venue. The mobile device can use a coarse location estimator to estimate a coarse location of the mobile device at the venue. The mobile device can request, from a server, detailed location data associated with the coarse location. The detailed location data can include location fingerprint data associated with a portion of the venue that includes the coarse location. The mobile device can determine an estimated location that has finer granularity than the coarse location using the location fingerprint data.
    • 描述了用于减少位置搜索空间的方法,程序产品和系统。 移动设备在到达场地时可以使用来自与场地相关联的一个或多个信号源的信号来确定移动设备的位置。 移动设备可以使用粗略位置估计器来估计移动设备在场地的粗略位置。 移动设备可以从服务器请求与粗略位置相关联的详细位置数据。 详细的位置数据可以包括与包括粗略位置的场地的一部分相关联的位置指纹数据。 使用位置指纹数据,移动设备可以确定具有比粗略位置更精细的粒度的估计位置。

    • Techniques of category-based fence are described. A category-based fence can correspond to a group of signal sources instead of a point location fixed to latitude and longitude coordinates. The group of signal sources can represent a category of entities, e.g., a particular business chain. The signal sources can be distributed to multiple discrete locations. A category-based fence associated with the group, accordingly, can correspond to multiple locations instead of a single point location and a radius. Each signal source in the group can be associated with a category identifier unique to the group and uniform among signal sources in the group. The category identifier can be programmed into each signal source. A mobile device can enter the category-based fence by entering any of the discrete locations when the mobile device detects the signal identifier. The mobile device can then execute an application program associated with the category-based fence.
    • 描述基于类别的围栏的技术。 基于类别的围栏可以对应于一组信号源,而不是固定在纬度和经度坐标上的点位置。 信号源组可以表示实体的类别,例如特定的业务链。 信号源可以分布到多个离散位置。 相应地,与组相关联的基于类别的栅栏可以对应于多个位置而不是单个点位置和半径。 组中的每个信号源可以与组中唯一的类别标识相关联,并且在组中的信号源之间是均匀的。 类别标识符可以编程到每个信号源中。 当移动设备检测到信号标识符时,移动设备可以通过输入任何离散位置来进入基于类别的围栏。 然后,移动设备可以执行与基于类别的围栏相关联的应用程序。
