Abstract
A method and apparatus for assigning location estimates from a first transceiver of a plurality of wireless transceivers to a second transceiver is disclosed. The present invention makes use of a low power short-range auxiliary communication link incorporated within networked devices to interact with nearby devices for obtaining location estimates of the current location of a device. Confidence levels are then assigned to the information obtained from the interactions with the nearby devices, and a determination of whether to update the location estimate is made.
