Title
(EN) WIRELESS DESKTOP AREA NETWORK SYSTEM
(FR) SYSTEME DE RESEAU DE ZONE DE BUREAU SANS FIL
Abstract
(EN) A wireless Desktop Area Network (DAN) system that includes a CSMA/CA multiple access control scheme, which is illustrated in figures 6A and 6B, with Collision Avoidance implemented in a serial bus protocol, and an automated network configuration process, which is illustrated in figure 7, to accomodate wireless communication among multiple network nodes, each of which is shown in figure 5A.
(FR) Réseau de zone de bureau (DAN) sans fil qui comporte un schéma de commande d'accès multiple par détection de porteuse et évitement de collision (CSMA/CA) illustré aux figures 6A et 6B, l'évitement de collision étant mis en oeuvre dans un protocole de bus sériel, et un processus automatisé de configuration de réseau, illustré à la figure 7, permettant la communication sans fil entre des noeuds de réseau multiples, chacun étant représenté à la figure 5A.
