Abstract
Un sistema de comunicaciones de doble vía para la comunicaión entre una red de un sistema y una unidad móvil. La red del sistema incluye una variedad de transmisores base y de receptores base incluidos en la red. Los transmisores base se dividen en asignaciones zonales y transmiten en transmisión simultánea usando técnicas de modulación de portadoras múltiples. La red del sistema controla los transmisores base a transmitir en transmisión simultánea durante intervalos a todo el sistema e intervalos de tiempo zonal. La red del sistema altera en forma dinámica los límites de zona para maximizar la capacidad de transmisión de la información. El sistema también usa una unidad móvil que recibe mensajes de la red y que transmite mensajes a la red. La unidad móvil incluye un interruptor que permite que el usuario solicite a la red que retransmita un mensaje recibido que contenga errores.
