1. A method, comprising:
- receiving a reported position associated with a wireless transmitter;
estimating a position of a mobile station at a first point in time;
calculating a range between the reported position associated with the wireless transmitter and the estimated position of the mobile station; and
determining whether the reported position associated with the wireless transmitter is sufficiently accurate in accordance with an accuracy metric based at least in part on the calculated range and based at least in part on one or more measurements related to one or more signals transmitted by the wireless transmitter at approximately the first point in time.

Abstract
The subject matter disclosed herein relates to determining whether a reported position of a wireless transmitter is sufficiently accurate in accordance with an accuracy metric based at least in part on a calculated range between an estimated position of a mobile station and the reported position and also based at least in part on one or more measurements taken from one or more signals transmitted by the wireless transmitter.
