Abstract: Disclosed is a method and apparatus for utilizing pressure sensor reliability during indoor positioning performed by a mobile device. The method may include performing an indoor positioning process on the mobile device to estimate a current location of the mobile device within an indoor environment. The method may also include analyzing a mapping between indoor positions and pressure sensor measurement reliability. Furthermore, the method may also include altering a usage of pressure sensor measurements collected by the mobile device for the indoor positioning process at the current estimated location of the mobile device within the indoor environment responsive to the mapping indicating that the estimated current location of the mobile device within the indoor environment is associated with an unreliability of pressure sensor measurements.

Abstract: Disclosed herein are methods, systems, and apparatuses for identifying a small cell in a wireless communication network. In one embodiment, a method includes receiving information associated with one or more base stations, where the information includes one or more codes associated with the one or more base stations. The method further includes determining whether a code from the one or more codes is associated with a small cell based on, for example, a number of base stations associated with the code; an aggregated area of coverage of the base stations associated with the code; signal strength information of a signal received by a mobile device from a base station of the one or more base stations; information indicating a distance or a data throughput between the mobile device and the base station; or an area of coverage of a base station associated with the code.

Abstract: Methods, apparatuses, and devices are disclosed to estimate a position of a mobile device using, for example, beacon signals transmitted using virtual access points utilizing a single, physical transceiver. Determination that beacon signals emanate from a single, physical transceiver may be based, at least in part, on a similarity among acquired beacon signals conveying identifiers, such as media access control identification (MAC ID) addresses and/or basic service set identifiers (BSSIDs), and on measurement of beacon signal characteristics, such as received signal strength at a mobile device and/or round trip time between the mobile device and the transceiver.

Abstract: Techniques provided herein are directed toward adjusting the rate at which a mobile device's barometric pressure sensor takes measurements, based on whether movement is detected from motion sensors, such as accelerometers, gyroscopes, and the like. Where movement is below a threshold (e.g., below a threshold speed or within a threshold distance), then the barometric pressure sensor can reduce the sampling rate to a rate that still enables the mobile device to account for changes in the weather. If movement is detected (e.g., greater than a threshold distance), then the sampling rate of the barometric pressure sensor increases (i.e., to a normal rate for determining vertical movement changes).
