Abstract

Un método y un detector para detectar alteraciones de radio en un sistema de comunicación por radio que comprende un dispositivo de puerta de enlace y un dispositivo periférico, estando cada uno dispuesto para enviar señales de radio a y para recibir señales de radio desde el otro. El método comprende medir el nivel de potencia (Pm) de los segmentos de información separados de las señales de radio recibidas por un dispositivo desde el otro dispositivo, determinar un valor estadístico (Pd) de los valores de nivel de potencia medidos, comparar un nivel de potencia medido seleccionado con el valor estadístico y producir una señal de alerta, que indica una alteración de radio, si la diferencia entre el nivel de potencia medido seleccionado y el valor estadístico supera un umbral. El detector comprende un detector de nivel de potencia (62), una unidad de procesamiento (64) conectada operativamente al detector de nivel de potencia (62) y una unidad de memoria (66) que almacena una pluralidad de valores estadísticos.A method and detector for detecting radio tampering in a radio communication system comprising a gateway device and a peripheral device, each being arranged to send radio signals to and to receive radio signals from the other. The method comprises measuring the power level (Pm) of the separate information segments of the radio signals received by one device from the other device, determining a statistical value (Pd) of the measured power level values, comparing a level selected measured power level with the statistical value and produce an alert signal, indicating a radio disturbance, if the difference between the selected measured power level and the statistical value exceeds a threshold. The detector comprises a power level detector (62), a processing unit (64) operatively connected to the power level detector (62), and a memory unit (66) that stores a plurality of statistical values.
