Post-deployment calibration of wireless base stations for wireless position determination

摘要

Methods and apparatuses are directed to calibrating a misconfigured wireless access point. One method may include receiving a position of mobile station(s) and wireless signal model measurements derived from packets exchanged between the mobile station(s) and a plurality of wireless access points, receiving positions and/or identities of the plurality of wireless access points used in determining the position of the mobile station(s), comparing a position of the mobile station(s) with wireless signal model measurements, and identifying a misconfigured wireless access point based upon the comparing. Another method may include receiving positions associated with a plurality of wireless access points, determining a position of a mobile station based upon a wireless signal model, comparing the position of the mobile station and the wireless signal model with the positions associated with the plurality of wireless access points, and determining whether at least one wireless access point is misconfigured.

1. A method for identifying a misconfigured wireless access point used for determining a position of a mobile station, the method comprising:
receiving a position of at least one mobile station; receiving wireless signal model measurements based at least in part on packets exchanged between the at least one mobile station and a plurality of wireless access points; determining angles of arrival at the at least one mobile station of signals from the plurality of wireless access points based on packets received from the plurality of wireless access points; receiving information associated with the plurality of wireless access points used in determining the position of the at least one mobile station; comparing the wireless signal model measurements with expected wireless signal model values to identify differences between the expected wireless signal model values and the received wireless signal model measurements that exceed a predetermined threshold; identifying the misconfigured wireless access point based at least in part on the differences between the expected wireless signal model values and the received wireless signal model measurements that exceed the predetermined threshold; and isolating a position of the misconfigured wireless access point based at least in part on at least one of the angles of arrival of signals from the plurality of wireless access points.
