Abstract

Un método de comunicación por radiofrecuencia entre un transpondedor sin contacto (1A) y un lector, en el que al menos una banda lateral (BLI) de la frecuencia portadora (Fc) se utiliza para comunicar una respuesta del transpondedor por modulación de amplitud (V) de esta frecuencia portadora, caracterizado porque la modulación se aplica al menos en parte un nivel de modulación mayor al 100%, lo que causa una modulación negativa (MOD B).
