Abstract: In some implementations, a server device can improve Wi-Fi based location availability for sparse signal locations by augmenting Wi-Fi access point location data with additional Wi-Fi scan data that was collected near the sparse signal locations. The server can receive Wi-Fi access point scans from client devices, determine the locations of the Wi-Fi access points, and generate Wi-Fi access point tiles that include data describing the locations of access points in the geographic areas corresponding to the Wi-Fi access point tiles. After the tiles are generated, the server device can augment the access point tiles by inserting additional Wi-Fi access point scan information into the access point tiles near identified sparse signal locations. The server device can deliver the augmented access point tile data to a client device. The client device can determine the current location of the client device based on the augmented access point tile data.

Abstract translation: 在一些实现中，服务器设备可以通过在稀疏信号位置附近收集的附加Wi-Fi扫描数据来扩充Wi-Fi接入点位置数据来改善针对稀疏信号位置的基于Wi-Fi的位置可用性。 服务器可以从客户端设备接收Wi-Fi接入点扫描，确定Wi-Fi接入点的位置，并生成Wi-Fi接入点瓦片，其中包括描述与Wi对应的地理区域中接入点位置的数据 -Fi接入点贴片。 在生成瓦片之后，服务器设备可以通过将附加的Wi-Fi接入点扫描信息插入识别的稀疏信号位置附近的接入点瓦片来扩充接入点瓦片。 服务器设备可以将增强的接入点瓦片数据传送到客户端设备。 客户端设备可以基于增强的接入点瓦片数据来确定客户端设备的当前位置。

Abstract: Described herein are techniques to enable a mobile device to determine a Z-axis coordinate based on altitudes associated with Wi-Fi access points detected in a Wi-Fi scan by the mobile device. One embodiment provides for an electronic device configured to compute a weighted average of Z-axis coordinates associated with detected Wi-Fi access points and determine a Z-axis coordinate for the electronic device based on the weighted average.
