Abstract: In one embodiment, Wi-Fi access point data is cached on a mobile client device in response to distances to WPS tile boundaries. The mobile client device identifies one or more Wi-Fi access points in range based on signals received by a Wi-Fi radio, and estimates its location utilizing the identified one or more Wi-Fi access points and Wi-Fi access point data of one or more Wi-Fi positioning system (WPS) tiles in a WPS tile store on the mobile client device. Based on the estimated location, the mobile client device determines it is within a threshold distance of a boundary of the one or more WPS tiles present in the WPS tile store and requests one or more new WPS tiles from a reference database of a remote server. Upon receipt, the one or more new WPS tiles are cached in the WPS tile store on the mobile client device.

Abstract translation: 在一个实施例中，响应于到WPS瓦片边界的距离，Wi-Fi接入点数据被缓存在移动客户端设备上。 移动客户端设备基于由Wi-Fi无线电接收的信号来识别范围内的一个或多个Wi-Fi接入点，并利用所标识的一个或多个Wi-Fi接入点和Wi-Fi接入点数据来估计其位置 或更多Wi-Fi定位系统（WPS）瓦片在移动客户端设备上的WPS瓦片存储中。 基于估计的位置，移动客户端设备确定它在WPS瓦片存储中存在的一个或多个WPS瓦片的边界的阈值距离内，并且从远程服务器的参考数据库请求一个或多个新的WPS瓦片。 一旦接收到，一个或多个新的WPS图块被缓存在移动客户端设备上的WPS平铺商店中。
