Abstract

Se describen un aparato, método y dispositivo inalámbrico para el escaneo rápido de un medio de comunicaciones inalámbricas. De acuerdo con un aspecto, un método incluye sintonizar un transceptor del nodo inalámbrico a una primera frecuencia. El método incluye además calcular una primera frecuencia de diferencia, en donde la primera frecuencia de diferencia es una diferencia entre la primera frecuencia y una segunda frecuencia. El método incluye además generar una primera señal de control para configurar un primer dispositivo de retrodispersión para cambiar entre al menos dos estados a una frecuencia de conmutación igual a la primera frecuencia de diferencia.
