Abstract
ES CONOCIDA LA TRANSMISION DE UNA INFORMACION DE SINCRONIZACION DESDE UNA ESTACION BASE MAESTRA A OTRAS ESTACIONES BASE (ESCLAVAS) A TRAVES DE LINEAS DE TRANSMISION. EL COMETIDO DE LA INVENCION ES LA DE EVITAR ESTOS COSTES RELATIVOS A LAS LINEAS DE TRANSMISION. PARA SOLUCIONAR ESTE COMETIDO, SE HA DISPUESTO EN UNA UNIDAD DE CONTROL PARA LA RED DE RADIOTELEFONIA (2) UN GENERADOR PARA UNA TENSION DE SINCRONIZACION (4). CON ESTA TENSION DE SINCRONIZACION SE MODULA LA CORRIENTE DE ALIMENTACION PARA LAS ESTACIONES BASE (6), SE TRANSMITE A TRAVES DEL YA EXISTENTE BUS SO, Y SE DEMODULA RESPECTIVAMENTE EN LA ESTACION BASE (6).
