Abstract

Se describe un método para controlar la energía de transmision en un sistema de comunicacion movil. El método descrito proporciona un método de control de energía de ciclo cerrado para transmisiones de velocidad variable. La energía de transmision varía de acuerdo con la velocidad de las estructuras de datos que están siendo transmitidas. La energía de transmision entre las velocidades puede ser una diferencia fija o variable.
