Title (EN) CONTENDING FOR THE MEDIUM WITH A MIXTURE OF BACKWARDS-COMPATIBLE WIRELESS DEVICES
(FR) CONTENTION POUR LE SUPPORT AVEC UN MELANGE DE DISPOSITIFS SANS FIL RETROCOMPATIBLES
Abstract:
(EN) In a wireless network in which a central network device (e.g., an access point) communicates with multiple generations of mobile wireless devices that are backward compatible but not forward compatible, each generation of device may be selectively put into a mode that permits contending for the medium or a mode that does not permit contenting for the medium, through the use of packets that are formatted to be recognizable by some generations but not all generations.
(FR) Dans un réseau sans fil dans lequel un dispositif de réseau central (par exemple un point d'accès) communique avec de multiples générations de dispositifs sans fil mobiles qui sont rétrocompatibles mais non compatibles vers l'avant, chaque génération de dispositifs peut de façon sélective se mettre dans un mode qui permet la contention pour le support ou un mode qui ne permet pas la contention pour le support, à travers l'utilisation de paquets formatés pour être reconnaissables par certaines mais pas par toutes les générations.
