Abstract: Systems, apparatus and methods for selecting a base station or a set of base stations for RTT measurements, or other interactive radio localization technique, to determine a position fix of a device are presented. The method imposes a processing load on only inactive or less active base stations. Busy or busier base stations are not used in the interactive radio localization technique. By imposing a processing load on only less active base stations, transmitting devices may be under loaded and encounter a more uniform processing delay, and thus provide a more accurate measurement resulting in a more accurate position fix.

Abstract: Various embodiments provide methods, devices, and non-transitory processor-readable storage media enabling network probing with a communication device based on the communication device sending a probe via a first network connection and receiving the probe via a second network connection. By leveraging a capability of a communication device to establish two network connections at the same time, various embodiments may enable a single communication device to act as both a probing client and a probing server. In this manner, various embodiments may enable standalone network probing, i.e., network probing that may not require a remote dedicated probing server to act as a probe generator or a probe sink.

Abstract: Methods, apparatuses, and non-transitory processor-readable media of the present disclosure are presented for efficiently executing applications based on pressure sensor data. In some embodiments, a method includes monitoring pressure, and determining a rate of change in the pressure over time exceeds a predetermined rate-of-pressure-change threshold. The method further includes subsequently determining that the rate of change in the pressure over time no longer exceeds the predetermined rate-of-pressure-change threshold. The method further includes determining a change in pressure has exceeded a predetermined pressure-change threshold, and performing floor disambiguation.

Abstract: Various embodiments include methods, and computing devices configured to implement the methods, for anomaly monitoring using context-based sensor output correlation. A computing device may obtain output of a first sensor and may determine that an anomaly is likely to occur based on the obtained output of the first sensor. The computing device may transmit a message indicating that the anomaly is likely to occur, causing receiving computing devices to begin logging output of sensors of the receiving computing devices. The computing device may determine whether the anomaly did occur. If the anomaly did occur, the computing device may transmit a sensor output request. Nearby computing devices may receive this sensor output request and may transmit collected sensor data to the first computing device. The first computing device may receive the sensor output collected by the various receiving devices and may correlate the first sensor output with the received sensor output.

Abstract: Systems, apparatus and methods for estimating a location of a mobile device are presented. Before computing a location estimate, the mobile device groups a plurality of access points into two or more categories (for example, a first list of access points having a first characteristic and a second list of access points having a second characteristic). Round-trip time (RTT) measurements are computed for access points in the first list. A Short Interframe Space (SIFS) value may be determined for each access point in the first list or generally SIFT representing the first list as a whole. The RTT measurements are compensated with the appropriate SIFS value. The mobile device then computes its location or position fix estimate using the compensated RTT values while excluding less accurate RTT values from other access points. As a result, the location estimate eliminates adverse influent from some access points.

Abstract: Disclosed are implementations, including a method, performed at a processor-based mobile device, that includes receiving at the mobile device antenna information for a wireless node, including a transmitter gain for the wireless node in at least one message transmitted to the mobile device. The at least one message includes, a beacon frame message, a fine timing measurement (FTM) protocol-based message, and/or an assistance data message transmitted from a remote central repository. The method also includes deriving an estimate of a receiver gain for a receiver of the mobile device based, at least in part, on the transmitter gain for the wireless node, and adjusting one or more signal strength values determined for signals received from the wireless node based on the estimate of the receiver gain of the receiver of the mobile device derived based, at least in part, on the transmitter gain for the wireless node.

Abstract: Various aspects include methods for profiling access points for a mobile communication device that includes a modem controlling a first radio access technology (RAT) and a second RAT. The device modem may establish a first level of communications with a potential network access point and obtain a first set of observed parameters of the potential network access point through the first level of communications. The modem may determine whether the first set of observed parameters of the potential network access point matches expected parameters for a network access point, and establish a second level of communications with the potential network access point in response to determining that the first set of observed parameters matches expected parameters of the network access point.
