Abstract:
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.
