A method (Figure 1), an apparatus, and code in a carrier medium to operate in a first access point (101) of a wireless network in communication with at least one associated client station (105). The method includes wirelessly broadcasting a management frame including an indication that the first access point will stop being active, such that each associated client station can wirelessly roam to a second access point prior to the first access point ceasing being active. One embodiment further includes reducing the transmit power of wireless communication used to wirelessly transmit information to the associated client stations, such that each associated client station can eventually wirelessly roam to the second access point.

L'invention concerne un procédé, un dispositif et du code dans un support pour exploitation dans un premier point d'accès d'un réseau sans fil en communication avec au moins une station client associée. Le procédé selon l'invention consiste à diffuser sans fil une trame de gestion contenant une indication signalant que le premier point d'accès va cesser d'être actif, de sorte que chaque station client associée peut passer en mode sans fil à un deuxième point d'accès avant que le premier point d'accès cesse d'être actif. Selon un mode de réalisation de l'invention, on réduit en outre la puissance d'émission de la communication sans fil utilisée pour transmettre sans fil des informations aux stations clients associées, de sorte que chaque station client associée peut tôt ou tard passer au deuxième point d'accès en mode sans fil.
