    摘要: Apparatuses and methods for detecting falsified wireless access points are presented. A method includes identifying a target wireless access point for validation and measuring a round trip time delay to the wireless access point. The method also includes determining an expected processing delay of the wireless access point, analyzing the measured round trip time delay and the expected processing delay, and validating the wireless access point based upon the analysis. An apparatus includes a wireless transceiver, a processing unit coupled to the wireless transceiver, and a memory coupled to the processing unit. The processing unit is configured to identify a target wireless access point for validation, measure a round trip time delay to the wireless access point, determine an expected processing delay of the wireless access point, analyze the measured round trip time delay and the expected processing delay, and validate the wireless access point based upon the analysis.

    摘要: The subject matter disclosed herein relates to systems, methods, apparatuses, devices, articles, and means for updating radio models. For certain example implementations, a method for one or more server devices may comprise receiving at one or more communication interfaces at least one measurement that corresponds to a position of a first mobile device within an indoor environment. At least one radio model that is stored in one or more memories may be updated based, at least in part, on the at least one measurement to produce at least one updated radio model. The at least one radio model and the at least one updated radio model may correspond to the indoor environment. The at least one updated radio model may be transmitted to enable a second mobile device to use the at least one updated radio model for positioning within the indoor environment. Other example implementations are described herein.

    摘要: The subject matter disclosed herein relates to a system and method for receiving, by a first mobile station, a signal transmitted from a second mobile station and addressed to a communication device (e.g., a communication device having a known location). The signal comprises a location estimate for the second mobile station. A range from the first mobile station to the second mobile station is estimated based at least in part on a measured signal strength of the received signal.

    摘要: One method for wirelessly determining a position of a mobile station includes measuring a round trip time (RTT) to a plurality of wireless access points, estimating a first distance to each wireless access point based upon the round trip time delay and an initial processing time associated with each wireless access point, estimating a second distance to each wireless access point based upon supplemental information, combining the first and second distance estimates to each wireless access point, and calculating the position based upon the combined distance estimates. Another method includes measuring a distance to each wireless access point based upon a wireless signal model, calculating a position of the mobile station based upon the measured distance, determining a computed distance to each wireless access point based upon the calculated position of the mobile station, updating the wireless signal model, and determining whether the wireless signal model has converged.
