Abstract

Cuando la medición de la calidad de comunicación usando una señal de banda ancha se realiza simultáneamente con la transmisión y recepción de datos usando una banda de frecuencia predeterminada, se evita el deterioro de calidad en la transmisión y recepción de datos; un aparato de transmisión (1) es capaz de transmitir datos utilizando una primera y una segunda frecuencias hacia un aparato de recepción (2); un transmisor (1a) del aparato de transmisión (1) transmite una señal de banda ancha predeterminada en una banda de frecuencia que no incluye la primera frecuencia en un primer período de tiempo y transmite la señal de banda ancha predeterminada en una banda de frecuencia que no incluye la segunda frecuencia en un segundo período de tiempo; una unidad de medición de calidad (2a) del aparato de recepción (2) mide la calidad de comunicación con el aparato de transmisión (1) basado en la señal de banda ancha recibida en los períodos de tiempo primero y segundo.
