Abstract: The position of a mobile device in a wireless network is refined by obtaining statistical samples of particles representing an initial estimated position of the device, obtaining one or more parameters of received signals from a set of one or more access points in the network, locking the set of one or more access points without using one or more additional access points to estimate the position, resampling the particles to obtain a second estimation of the position after locking the first set of one or more access points, and obtaining a refined estimated position based on a comparison of the first and second estimations of the position.

Abstract: Techniques for position estimation, e.g., of a mobile communication device, using trajectory are described herein. A method for estimating position of a mobile device described herein includes obtaining a routing graph corresponding to an area, wherein the routing graph indicates traversable paths through the area; collecting trajectory information corresponding to movement of the mobile device through the area; forming a trajectory graph from the trajectory information; comparing the trajectory graph to at least one subset of the routing graph to determine at least one matching subset of the routing graph; and estimating the position of the mobile device based at least in part on the at least one matching subset of the routing graph.

Abstract: Various methods, apparatuses and/or articles of manufacture are provided which may be implemented to estimate a trajectory of a mobile device within an indoor environment. In some embodiments, the trajectory may be estimated without the use of any signal-based positioning information. For example, a mobile device may estimate such a trajectory based, at least in part, on one or more sensor measurements obtained at the mobile device, and further affect the estimated trajectory based, at least in part, on one or more objects identified in an electronic map of the indoor environment.
