Abstract

APARATO DE COMUNICACIONES QUE COMPRENDE TRES TRANSCEPTORES (14, 16, 24) DISPUESTOS DE TAL MODO QUE LA COMUNICACION DE RADIO ENTRE UNA ANTENA DE UNA RED TELEFONICA Y UN MICROTELEFONO PORTATIL DE BAJA POTENCIA, QUE INCORPORA UNO DE LOS TRES TRANSCEPTORES (16), TIENE LUGAR A TRAVES DE DOS ENLACES DE COMUNICACION DE RADIO ACOPLADOS POR LOS OTROS DOS TRANSCEPTORES (14, 24). LA INTERFERENCIA ES REDUCIDA DEBIDO A QUE EL SEGUNDO ENLACE EL TRANSCEPTOR (16) PUEDE BASARSE EN RADIO-FRECUENCIAS ESENCIALMENTE DIFERENTES DE LAS SELECCIONADAS PARA EL PRIMER ENLACE ENTRE DICHA ANTENA Y LOS TRANSCEPTORES DE ACOPLAMIENTO (14, 24). ADEMAS, EL SEGUNDO ENLACE PUEDE ESTABLECERSE DE UNA MANERA INDEPENDIENTE DE LA NATURALEZA DEL PRIMER ENLACE, NO REQUIRIENDOSE UN ENLACE DE DATOS FIJO EN ADICION AL EQUIPO DE TRANMISION-RECEPCION DE COMUNICACION DE VOZ. EL INVENTO ENCUENTRA APLICACION PARTICULAR EN SISTEMAS DE RADIO-TELEFONOS CELULARES.
