Abstract

L'invention concerne un procédé et un dispositif de communications permettant à de multiples dispositifs source (110, 120, 130) de communiquer des informations à un dispositif de destination (100). Les informations communiquées d'un dispositif source quelconque vers le dispositif de destination (100) se présentent généralement sous forme d'informations de code ou d'identification (ID) de produit électronique binaires (EPC). Le mode préféré de l'invention utilise des techniques de brouillage et débrouillage de données; de sélection et transmission de canal; d'activation ou désactivation de transmissions de groupes; de corrélation; et de réduction de collision.
