Abstract

Un método para detectar la interferencia causada por la intermodulación en un sitio del nodo de la red que comprende un conjunto de nodos de red para comunicación inalámbrica capaz de realizar la comunicación con un conjunto de estaciones para comunicación inalámbrica. Las estaciones son dispositivos transreceptores inalámbricos y la comunicación del nodo de red a cualquiera de las estaciones se considera una comunicación de enlace descendente y la comunicación de cualquiera desde las estaciones se considera una comunicación de enlace ascendente. El método comprende determinar un nivel de interferencia de la señal de entrada recibida sobre por lo menos una parte de los recursos de comunicación para la comunicación de enlace ascendente, determinar un nivel de señal transmitido en por lo menos una parte de los recursos de comunicación para una comunicación de enlace descendente, en donde la por lo menos parte de los recursos de comunicación para la comunicación de enlace descendente corresponde en tiempo con la por lo menos parte de la comunicación de enlace ascendente, correlacionar las estadísticas del nivel de interferencia de señal de entrada recibida y el nivel de la señal transmitida determinado, y determinar si se encuentra presente interferencia significativa causada por la intermodulación en base a la correlación. Un programa de computadora, un controlador y un nodo de red también se divulgan.
