Abstract

L'invention concerne un procédé utilisant un appareil de point d'accès sans fil pour déterminer une orientation d'un terminal. Le procédé consiste : à fournir, dans un appareil de point d'accès sans fil, de multiples dispositifs de transmission-réception de paquet de données indépendants connectés électriquement et agencés de façon uniforme en un anneau ; lorsqu'un terminal transmet un paquet de données à l'appareil de point d'accès sans fil, à déterminer un premier dispositif qui reçoit le paquet de données comme premier dispositif de transmission-réception de paquet de données et un dernier dispositif qui reçoit le paquet de données comme dernier dispositif de transmission-réception de paquet de données ; et à déterminer une orientation du terminal par une direction rectiligne dans laquelle le dernier dispositif de transmission-réception de paquet de données et le premier dispositif de transmission-réception de paquet de données sont connectés. Lorsqu'une orientation d'un paquet de données est déterminée par de multiples appareils de point d'accès sans fil dans un espace, le paquet de données peut être partagé par d'autres appareils de point d'accès sans fil, permettant ainsi d'augmenter la précision de positionnement dans l'espace.
