An 802.11 source station (160-1) transmits a signal with the duration field other than that required for the transmission to prevent transmission by other stations during known sequences. Thus, the source station (160-1) uses the duration field to spoof the actual time the medium will be occupied, to stations within range of the signal. A station (160-4) within range for the transmitted signal will check the duration field of the transmitted signal, and update the station network allocation vector.
L'invention concerne une station source 802.11 (160-1) émettant un signal avec un champ de durée autre que celui exigé pour que l'émission empêche toute émission par d'autres stations lors de séquences connues. Ainsi la station source (160-1) utilise le champ de durée pour bluffer le temps réel pendant lequel le support est occupé, pour des stations comprises à l'intérieur de la plage du signal. Une station (160-4) comprise dans la plage du signal émis vérifie le champ de durée du signal émis et met à jour le vecteur d'attribution de réseau de station.
