Mostrar Mensajes MenúCitarQoS en escenarios inalámbricos
El entorno inalámbrico es muy hostil para medidas de Calidad de Servicio debido a su variabilidad con el tiempo, ya que puede mostrar una calidad nula en un cierto instante de tiempo. Esto implica que satisfacer la QoS resulta imposible para el 100% de los casos, lo que representa un serio desafío para la implementación de restricciones de máximo retardo y máxima varianza en el retardo (jitter) en sistemas inalámbricos.
Los sistemas de comunicaciones ya estandarizados con restricciones QoS de retardo y jitter en entornos inalámbricos (Ej. GSM y UMTS) sólo pueden garantizar los requisitos para un porcentaje (<100%) de los casos. Esto implica un "Outage" en el servicio, generando las cortes de llamadas y/o los mensajes de "red ocupada". Por otro lado, algunas aplicaciones de datos (Ej. WiFi) no requieren de restricciones de máximo retardo y jitter, por lo que su transmisión sólo necesita de la calidad media del canal, evitando la existencia del Outage.
