Definitions

  • a wireless Access Point is a networking hardware device that allows a Wi-Fi compatible client device to connect to a wired network and to other client devices.
  • the AP usually connects to a router (directly or indirectly via a wired network) as a standalone device, but it can also be an integral component of the router itself.
  • Several APs may also work in coordination, either through direct wired or wireless connections, or through a central system, commonly called a Wireless Local Area Network (WLAN) controller.

Abstract

L'invention concerne une coordination d'opération de sous-bande dynamique (DSO) à l'aide d'une coordination de points d'accès multiples (AP) (MAPC). La coordination de DSO peut comprendre la détermination d'un accord DSO inter-ensembles de services basiques (BSS) proposé pour un BSS en chevauchement (OBSS) et l'envoi d'une demande DSO inter-BSS à l'OBSS sur la base de l'accord DSO inter-BSS proposé. Une réponse DSO inter-BSS est reçue en provenance de l'OBSS. Lorsque la réponse DSO inter-BSS accepte l'accord DSO inter-BSS proposé, l'accord DSO inter-BSS proposé est établi.
