Title
(EN) CONTROLLING MOTION TOPOLOGY IN A STANDARDIZED WIRELESS COMMUNICATION NETWORK
(FR) COMMANDE DE TOPOLOGIE DE MOUVEMENT DANS UN RÉSEAU DE COMMUNICATION SANS FIL STANDARDISÉ
Abstract
(EN) In a general aspect, a motion sensing topology of a multi-access point (multi-AP) wireless communication network can be controlled. In some aspects, the multi-AP wireless communication network includes a first AP device, a second AP device, and a multi-AP controller. The multi-AP controller identifies a wireless communication topology, which includes identifying that a first client station device is associated with the first AP device. The multi-AP controller defines a motion sensing topology that is different from the wireless communication topology, and the motion sensing topology includes a wireless motion sensing link between the first client station device and the second AP device. The multi-AP controller initiates a motion sensing measurement based on the motion sensing topology, and the motion sensing measurement uses the wireless motion sensing link while the first client station device remains associated with the first AP device.
(FR) Selon un aspect général, une topologie de détection de mouvement d'un réseau de communication sans fil à points d'accès multiples (multi-AP) peut être commandée. Selon certains aspects, le réseau de communication sans fil multi-AP comprend un premier dispositif AP, un second dispositif AP et un contrôleur multi-AP. Le contrôleur multi-AP identifie une topologie de communication sans fil, qui consiste à identifier qu'un premier dispositif de station client est associé au premier dispositif AP. Le contrôleur multi-AP définit une topologie de détection de mouvement qui est différente de la topologie de communication sans fil, et la topologie de détection de mouvement comprend une liaison de détection de mouvement sans fil entre le premier dispositif de station client et le second dispositif AP. Le contrôleur multi-AP déclenche une mesure de détection de mouvement sur la base de la topologie de détection de mouvement, et la mesure de détection de mouvement utilise la liaison de détection de mouvement sans fil tandis que le premier dispositif de station client reste associé au premier dispositif AP.
