Abstract

La présente invention concerne un procédé de limitation de la portée de systèmes de télécommande, et de préférence de systèmes de radiocommande, dans lequel les signaux de commandes sont émis depuis, de préférence, un émetteur mobile (1), à destination d'un récepteur (2) destiné à commander un objet à commander (3). En l'occurrence, le procédé consiste à mesurer l'intensité de signal du signal reçu, laquelle mesure sert de base de calcul de la limite de portée. La caractéristique particulière du procédé est que la valeur de pointe de l'intensité de signal des signaux reçus est évaluée pendant la transmission des signaux à la limite (L) de portée souhaitée, laquellle valeur sert de base de calcul d'une valeur limite pour l'intensité de signal des signaux reçus. L'invention concerne également un système de limitation de la portée de systèmes de télécommande.
