Title
(EN) SHORT RANGE RF NETWORK
(FR) RESEAU RF A FAIBLE PORTEE
Abstract
(EN) A network including a host device and a plurality of transceiver beacons for communicating data from terminal devices interacting with the beacons, to the host. The beacons include identification codes used by the host for establishing wireless communication links either between a beacon and the host, or between two or more beacons. A routing mechanism is included in the beacons for selecting a most favorable transmission path among available paths for communicating data to the host.
(FR) La présente invention concerne un réseau comprenant un dispositif hôte et une pluralité de balises d'émetteur-récepteur qui transmettent à l'hôte, des données provenant de dispositifs terminaux interagissant avec les balises. Les balises comprennent des codes d'identification utilisés par l'hôte pour établir des liaisons de communication sans fil soit entre une balise et l'hôte soit entre au moins deux balises. Un mécanisme d'acheminement est intégré dans les balises afin de sélectionner le chemin de transmission le plus favorable parmi les chemins disponibles pour transmettre les données à l'hôte.
