(EN) HIGH-SPEED WIRELESS NETWORK WITH A RELIABLE WIRELESS LOW BIT-RATE CHANNEL
(FR) RESEAU SANS FIL EXTREMEMENT RAPIDE POSSEDANT UNE VOIE FIABLE SANS FIL A DEBIT BINAIRE LIMITE
Abstract
(EN)
A multichannel wireless network (60), methods for its operation, and system components are disclosed. The network is designed to facilitate high-bit-rate data communication within a home, office, or similarly constrained area. According to the described embodiments, at least two different types of wireless channels form the network infrastructure. A primary wireless channel is designed for relatively low bit rate, high reliability and network-wide communication. A secondary wireless channel is designed for relatively high bit rate communication, but with potentially lower reliability and shorter ranges. A base station (62) uses the primary wireless channel to configure and control operation of the wireless network (60), including configuring pairs of devices as requested for direct communication over the secondary wireless channel.

Réseau sans fil (60) possédant des voies multiples, procédés concernant sa mise en application et composantes du système. Ce réseau est conçu pour faciliter une communication de données à débit binaire élevé dans un lieu d'habitation, un bureau ou une zone similaire restreinte. Selon les modes de réalisation décrits, au moins deux différents types de voies sans fil constituent l'infrastructure du réseau. Une première voie sans fil est conçue pour une communication présentant un débit binaire relativement limité et une fiabilité importante sur la totalité du réseau. Une deuxième voie est conçue pour une communication présentant un débit binaire relativement élevé mais une fiabilité potentiellement plus limitée et une portée plus courte. Une station de base (62) utilise la première voie afin d'effectuer la configuration et la commande de l'opération du réseau (60), y compris la configuration de paires de dispositifs nécessaires à une communication directe par l'intermédiaire de la deuxième voie.
