Abstract

La présente invention concerne un procédé de transmission de données depuis et/ou vers un compteur de consommation dans un système de radiocommunication comprenant une pluralité de points terminaux pourvus d'un dispositif de mesure destiné à acquérir des données de consommation, une pluralité d'unités de transmission de données, un collecteur de données et un système de gestion de données. Les unités de transmission de données sont reliées en réseau par voie hertzienne et envoient des télégrammes de disponibilité à la réception avec des informations d'identification. Elles basculent ensuite temporairement dans un mode de réception dans lequel elles reçoivent un télégramme d'activation de la part d'unités de transmission de données voisines ou d'un collecteur de données et le mettent en mémoire.
