System and method for selecting a Wi-Fi access point for position determination

摘要

Methods, systems, computer-readable media, and apparatuses for position determination are presented. In some embodiments, a method for position determination includes selecting at least one of a plurality of access points based on a measure of response time variability associated with the at least one access point. The method further includes sending, from a device, a communication to the selected at least one access point. The method also includes receiving, from the selected at least one access point, a response to the communication. The method additionally includes calculating a distance from the device to the selected at least one access point based on a round trip time associated with the response to the communication.

1. A method for selecting a Wi-Fi access point for position determination, comprising:
obtaining, by a mobile device, data comprising a measure of variance in response time associated with each of a plurality of access points; selecting, by the mobile device, at least one of the plurality of access points for use in a communication for a distance determination, the selecting based on the obtained data, the selected at least one access point having a lower variance in response time than one or more other access points among the plurality of access points; sending, by the mobile device, a communication to the selected at least one access point; receiving, by the mobile device, from the selected at least one access point, a response to the communication; and calculating, by a mobile device, a distance from the device to the selected at least one access point based on a round trip time determined based on the communication and the response to the communication.
