Abstract

Un procedimiento de identificación de una pluralidad de transpondedores (1, 2, 3) en un sistema de interrogación que comprende la transmisión de una señal de interrogación a los transpondedores (1, 2, 3) y la recepción de las señales de respuesta procedentes de los transpondedores (1, 2, 3), siendo cada transpondedor (1, 2, 3) capaz de transmitir la señal de respuesta en cualquier momento durante un periodo de espera, caracterizado porque cada transpondedor (1, 2, 3) podría alterar la extensión máxima del periodo de espera durante el procedimiento de interrogación para retransmitir la señal de respuesta en un tiempo aleatorio durante ese periodo de espera alterado.
