Abstract

La présente invention concerne un dispositif et un procédé pour sélectionner un trajet d'amélioration multibond d'un relais de communication coopérative Wi-Fi, où le routage est possible en tenant compte d'une efficacité d'émission d'un relais, et des données requises par un terminal sont divisées et fournies par le relais. Selon la présente invention, un dispositif pour sélectionner un trajet d'amélioration multibond d'un relais de communication coopérative Wi-Fi comprend : un premier point d'accès, AP, relais pour émettre ou recevoir des données avec un réseau ; un second AP relais pour émettre ou recevoir des données via le premier AP relais ; et un terminal pour émettre ou recevoir des données via le premier AP relais et/ou le second AP relais.
