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： 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.

摘要： Apparatus and methods are directed to calibrating a delay within a wireless access point for determining a position of a mobile station. One method includes receiving an initial packet at an eavesdropping device, receiving a response packet, sent by another entity, at the eavesdropping device, computing a time difference based upon the packet arrival times, and providing the time difference to a position determination entity. Another method includes providing a request to appropriate eavesdropping devices to send information, receiving, from each appropriate eavesdropping device, a time difference which represents a difference in a time of arrival of a packet transmitted by the wireless access point and a time of arrival of a packet transmitted by the mobile station, determining a processing delay estimate based upon the time differences, and determining a position of the mobile station based upon the processing delay estimate and the received time differences.

摘要： Techniques are provided that may be implemented in various methods and apparatuses to allow an electronic device to determine when it is transitioning or has transitioned from a first environment to a second environment based, at least in part, on at least one measured parameter. The measured parameter may be based, at least in part, on one or more received wireless signals associated with one or more wireless signal transmitters, and/or one or more signals associated with one or more non-radio sensors. The electronic device may then affect operation of a navigation function (e.g., having a trajectory estimation filter) based, at least in part, on the measured parameter.

摘要： Apparatuses and methods for adjusting wireless-derived positions of a mobile station using a motion sensor are presented. One method includes estimating a position of a mobile station based upon wireless signal measurements and measuring a movement of the mobile station using a relative motion sensor. The method further includes detecting a displacement of the mobile station based upon the measured movement, determining that the displacement is below a threshold and then adjusting the estimated position of the mobile station using information from the relative motion sensor. An apparatus includes a wireless transceiver, a relative motion sensor, a processor coupled to the wireless transceiver and the relative motion sensor, and a memory coupled to the processor. The memory stores executable instructions and data for causing the processor to execute methods for adjusting wireless-derived positions using a motion sensor.
