1. A method for determining a processing time for wirelessly determining a position of a mobile station, comprising:
sending, by a transceiver within a mobile station, one or more requests to a network of wireless access points; receiving, by the transceiver, a response from each of a plurality of access points of the network of access points; determining, by a processor within the mobile station, a round trip time delay from the mobile station to each of the plurality of access points, the round trip time delay for each access point of the plurality of access points including:
a first propagation time from the sending of a one of the requests by the transceiver to a receipt of the request by the respective one of the plurality of access points,a processing time from the receipt of the request by the respective access point to the sending of the response by the access point to the mobile station, anda second propagation time from the sending of the response by the access point to a receipt of the request by the transceiver; estimating, by the processor, the processing time for each of the plurality of access points; calculating, by the processor, a position of the mobile station based upon the determined round trip time delays and the estimated processing times; and updating, by the processor, the estimated processing time for each of the plurality of access points based upon the calculated position of the mobile station. |
