<P>PROBLEM TO BE SOLVED: To provide methods, programs, and systems for location estimation using multiple wireless access gateways. <P>SOLUTION: A mobile device 100 can scan and detect multiple wireless access gateways. The mobile device can determine an initial estimate of distance between the mobile device and each wireless access gateway. The mobile device can receive, from a server 108, location data 109 of the detected wireless access gateways. The location data can include an estimated location of each wireless access gateway, an uncertainty of the estimated location, and a reach of each wireless access gateway. The mobile device can assign a weight to each estimated location using the uncertainty, the reach, and the initial estimate. The mobile device can estimate the location of the mobile device using the weighted locations. <P>COPYRIGHT: (C)2013,JPO&INPIT |
