(EN) POWER EFFICIENT AND FLEXIBLE UPDATE RATE POSITIONING SYSTEM
(FR) SYSTÈME DE LOCALISATION À FAIBLE CONSOMMATION D'ÉNERGIE ET FRÉQUENCE D'ACTUALISATION ADAPTABLE
Abstract
(EN) Methods, systems, and devices for automatically changing the manner in which a tag unit communicates with one or more access points based on the tag unit's mobility state are described. A tag unit may transmit ultra-wideband (UWB) signals in a low update mode while in a stationary state. The tag unit may transmit UWB signals in a high update mode while in a mobile state. The tag unit, an access point, and/or a tracking management server may determine a tag unit's mobility state and adjust an update mode based on the mobility state.
(FR) L'invention concerne des procédés, des systèmes et des dispositifs qui permettent de changer automatiquement la manière dont une unité de communication communique avec un ou plusieurs points d'accès, en fonction de l'état de mobilité de ladite unité. Une unité de communication peut émettre des signaux à bande ultralarge (UWB) en mode actualisation lente pendant qu'elle est à l'état immobile. Ladite unité de communication peut émettre des signaux UWB en mode actualisation rapide pendant qu'elle est à l'état mobile. L'unité de communication, un point d'accès et/ou un serveur de gestion de suivi peuvent déterminer l'état de mobilité d'une unité de communication et ajuster le mode d'actualisation sur la base de l'état de mobilité.
