Abstract: Positioning systems may be used to determine the location of computing devices in space. Described herein are systems, methods, and computer readable mediums for storing information determined to be reliable that is used to determine the location of a computing device. In some implementations, the system determines that a scan list is reliable based on factors such as characteristics associated with the type of device that generated the scan list, or based on the amount of times that the information in the scan list was detected over a period of time.

Abstract: Approaches enable a device, such as a cellular-enabled device, to receive cellular system information from another device in response to a request by the cellular-enabled device, and then to select a cellular network connection to which the cellular-enabled device can connect based on the cellular system information. The cellular-enabled device may determine the availability of the cellular system information in a number of ways, such as by detecting a Bluetooth broadcast from another device and initiating a paired connection between the two devices. Once the paired connection is established, the cellular-enabled device may make a service discovery request to learn that the other device is capable of broadcasting the cellular system information over the connection between the devices. The cellular system information may be used by the cellular-enabled device to select one cellular network connection, from a set of available cellular network connections compatible with the cellular-enabled device, to connect to.
