Abstract

L'invention concerne un système de courant porteur en ligne qui contient un dispositif de couplage de signaux contenant une entrée destinée à recevoir un signal de communications d'un réseau de communications ; et une sortie destinée à transmettre le signal de communications à des dispositifs transducteurs de signaux haute fréquence. Chaque dispositif transducteur de signaux haute fréquence peut être couplé à une ligne électrique, de manière à permettre la transmission (par exemple par couplage électromagnétique) du signal de communications haute fréquence (par exemple 10MHz à 30MHz), sans connexion directe aux lignes électriques à courant alternatif, normal à faible tension classique (par exemple 110V à 220V).
