Claim Text:
1. A method for identifying access points (APs) that provide reliable signaling, the method comprising: obtaining a first set of distance data representing multiple calculated distances between a first access point (AP) and a mobile device in an indoor area, wherein the multiple calculated distances are calculated based on a round trip time (RTT) information derived from communications with the first AP at multiple locations of the mobile device within the indoor area; obtaining a distance threshold for the indoor area, wherein the distance threshold is based on dimensions of the indoor area; determining, based on a comparison of the first set of distance data and the distance threshold, that a reliability condition is satisfied with respect to the first AP; and in response to determining that the reliability condition is satisfied with respect to the first AP, identifying the first AP for a RTT-based location determination.
