Abstract
Official abstract text for this publication.
Systems, methods and apparatuses for estimating a location within an area are disclosed. One method includes determining a plurality of wireless signal signatures at a plurality of locations within the area, wherein each wireless signal signatures includes a characteristic of a plurality of wireless links between a device and a plurality of network access points at a one of the plurality of locations, wherein the plurality of wireless signal signatures are received by a network manager server. Further, the network manager server receives a present wireless signal signature of a current device. The method further includes estimating locations the current device, including comparing a present wireless signal signature of the current device with plurality of wireless signal signatures, and adaptively re-determining the plurality of wireless signal signatures based on at least one condition of a distributed wireless network that includes the plurality of network access points.
First claim
