Abstract

L'invention concerne un procédé et un appareil de positionnement à ultralarge bande. Un mode de réalisation particulier du procédé consiste : en réponse au contrôle de premières données de diffusion Bluetooth, à réinitialiser un paramètre de positionnement, lequel est incompatible avec un paramètre de positionnement indiqué par les premières données de diffusion Bluetooth, parmi des paramètres de positionnement définis, les premières données de diffusion Bluetooth comprenant au moins un élément parmi un canal de transmission de données, un débit de transmission de données et une fréquence de transmission de données qui sont tous configurés par une station de base de positionnement pour être communiqués ; et à envoyer un signal de positionnement à la station de base de positionnement sur la base du paramètre de positionnement actuellement défini et d'un mode de positionnement à ultralarge bande, de sorte que la station de base de positionnement et un serveur de positionnement déterminent la position actuelle en fonction du mode de positionnement à ultralarge bande configuré. Selon le mode de réalisation, les paramètres de positionnement d'une étiquette de positionnement peuvent être réinitialisés automatiquement.
