description | Methods and systems are presented for estimating a location of an access point (AP) associated with an indoor environment. In some embodiments a method includes obtaining a coarse set of signal information associated with the indoor environment. The method may also include obtaining ranging measurements based on signals received from the AP, computing at least one coarse location estimate of the AP based on the received coarse set of signal information and the ranging measurements, receiving a fine set of signal information associated with the at least one coarse location estimate of the AP, and computing at least one fine location estimate of the AP based on the received fine set of signal information and the ranging measurements, wherein the at least one fine location estimate of the AP is more accurate than the at least one coarse location estimate of the AP.
L'invention concerne des procédés et des systèmes présentés pour estimer un emplacement d'un point d'accès (AP) associé à un environnement intérieur. Dans certains modes de réalisation, un procédé comprend l'obtention d'un ensemble de grossier d'informations de signal associées à l'environnement intérieur. Le procédé peut également comprendre l'obtention de mesures de télémétrie sur la base des signaux reçus en provenance de l'AP, le calcul d'au moins une estimation d'emplacement approximatif de l'AP sur la base de l'ensemble grossier reçu d'informations de signal et des mesures de télémétrie, la réception d'un ensemble précis d'informations de signal associées à la ou aux estimations d'emplacement approximatif de l'AP, et le calcul d'au moins une estimation d'emplacement précis de l'AP en se basant sur l'ensemble précis reçu d'informations de signal et les mesures de télémétrie, la ou les estimations d'emplacement précis de l'AP étant plus précises que la ou les estimations d'emplacement approximatif de l'AP. |
