Abstract: In some implementations, a computing system can perform crowd sourced access point mapping using privacy preserving techniques. For example, a server device can receive access point data reports from multiple user devices that includes various attributes and/or measurements with respect to access points with which the user devices have established connections. The access point data reports can be delivered without identifying the user devices, or users thereof, and their exact locations. Based on the access point data reports, the server device can map locations of access points and relationships between access points to generate network topologies, network locations, network quality scores, and various other characteristics of networks and/or access points. The generated access point data can be served to user devices so that the user devices can improve the efficiency of the interactions between user devices and the detected access points and/or networks.

Abstract: Embodiments herein provide apparatuses and techniques for providing a notification indicating guidance to reaching cellular connectivity in the event of a loss of cellular connectivity and for guiding a user of a user equipment to a location with cellular connectivity. The notification may be generated based on expiration of a timer, a screen unlock operation, or an application connection failure. The notification may indicate how long ago the cellular connectivity loss occurred and how far away a nearest location is with a cellular connectivity was. The user equipment may display a map interface based on user input selecting the notification. The map interface may show a map of the current location of the user equipment, a nearest location with cellular connectivity to the user equipment, and a path, which includes a tracked path of user equipment and a proposed path to the nearest location with cellular connectivity.

Abstract: A distributed offline indexing system uses a set of data processing systems in a distributed computing environment to create an index database that can store, for example, data about geographical or geospatial areas. The index database can be distributed across a plurality of database shards such that each shard includes an index file and a DB file. The index files include keys that refer to values in their corresponding DB files. The keys are used to look-up their corresponding values at search time. At indexing time, the keys are hashed, with an entropy creating hash, to distribute the keys across the shards.

Abstract: A method may include accessing service data associated with a service and associated with a group of geographical regions. The method may also include assigning at least some of the service data of the group of geographical regions corresponding to a map tile. The method may include generating an initial batch of service data corresponding to the map tile, thereby generating initial batches of service data. The method may also include receiving, from a mobile device, a request to download map data corresponding a geographical area. The method may also include determining one or more map tiles corresponding to the geographical area. The method may also include determining a subset of the initial batches associated with the one or more map tiles corresponding to the geographical area. The method may also include providing, to the mobile device, the subset of the initial batches responsive to the request.
