Abstract

L'invention concerne une solution permettant la transmission de données sans fil entre une station de base (2) d'un réseau radio mobile et un appareil électronique (1, 1', 1", 1"') qui est équipé d'au moins une unité d'émission-réception pour un échange de données sans fil et qui se trouve dans la zone de réception incertaine du réseau radio mobile de la station de base (2) ou qui n'est pas réalisé pour le réseau radio mobile. L'invention vise à permettre quand même un échange de données entre l'appareil électronique mentionné ci-dessus (1, 1', 1", 1"') et la station de base (2). A cet effet, les données sont transmises par l'intermédiaire d'un dispositif de conversion (3) ajouté sur la voie de transmission. Selon l'invention, la transmission des données entre la station de base (2) et le dispositif de conversion (3) se fait par l'intermédiaire du réseau radio mobile de la station de base (2), et la transmission des données entre le dispositif de conversion (3) et l'appareil électronique (1, 1', 1", 1"') se fait conformément à la norme et en utilisant les protocoles du réseau radio mobile utilisé pour la transmission des données entre la station de base (2) et le dispositif de conversion (3), mais en utilisant une porteuse différente de la porteuse du réseau radio mobile, au moins en ce qui concerne sa fréquence porteuse. Les données à transmettre, de préférence des instructions AT, sont converties dans le dispositif de conversion (3) respectivement sur l'autre porteuse.
