    摘要: Disclosed are methods, systems and devices for providing location based services in a venue. To estimate its location, in a particular implementation, a mobile device may obtain a measurement of a range to a transponder device positioned at a known location based on measurements of a signal round-trip time (RTT) in a message exchange with the transponder device. Positioning assistance data from a server may enable the mobile device to measure a delay at the transponder device in providing a response to a probe message to thereby more accurately measure the signal RTT.

    摘要: A mobile device includes a receiver to obtain three-dimensional geographic information identifying at least one open area and at least a height associated with at least one object adjacent to the at least one open area, determine at least one pathway in the open area, and determine expected line of sight and expected non-line of sight detections of satellite positioning system (SPS) signals at locations along the pathway based on the three dimensional geographic information. The mobile device includes a processing unit to estimate a location of the mobile device based on application of the expected line of sight detections and the non-line of sight detections to signals acquired at the receiver.

    摘要: Disclosed are systems, apparatus, devices, methods, media, products, and other implementations, including a method that includes controllably modifying, at a first wireless device, an original unmodified value of at least one PHY-layer signal parameter, such as amplitude, frequency, timestamp, gain, signal equalization, and/or any combination thereof, of a signal according to at least one pre-determined varying signal modification process. The method further includes transmitting to a second wireless device the signal with the controllably modified value of the at least one PHY-layer signal parameter, with the transmitted signal configured to facilitate position determination of the second wireless device when the original unmodified value of the at least one PHY-layer signal parameter is determined at the second wireless device from the controllably modified value of the at least one PHY-layer signal parameter.

    摘要: Various techniques are provided which may be implemented as methods, apparatuses and articles of manufacture for use by a mobile device. In certain example implementations, a mobile device may process a barometric pressure measurement indicative of an altitude effect and a weather effect to determine a first parameter corresponding to the altitude effect and a second parameter corresponding to the weather. Such a mobile device may further determine whether it may be transitioning or may have transitioned from an initial level to another level of a multiple level structure based, at least in part, on the first and second parameters.

    摘要: Disclosed are systems, methods and devices for application of determining position information for mobile devices. In specific implementations, measurement of a signal travel time and a signal's strength may be combined to characterize a transmission power of the signal's transmitter. The characterized transmission power may be applied to affect expected signal strength signature values for use of the signal's transmitter may be updated in order to enhance a location based service where location may be effected by accuracy of a transmitter's power.
