Abstract
Una disposicion sincroniza tiempo y frecuencia de multiples radioestaciones de base privadas que operan en el área de cobertura de unared terrestre de comunicaciones moviles. Los canales de control de la red movil se utilizan para derivar una senal de referencia. Una terminal movil usala senal de referencia para sincronizarse tanto en tiempo como en frecuencia con la red movil. Cualquiera de las radioestaciones de base privadas que seenlaza en una conexion de tráfico conla terminal movil, se sincroniza con la terminal movil. Consecuentemente, las radioaestaciones de base privadasestán indirectamente sincronizadas entre sí y también con la red de comunicaciones moviles.
