Abstract
EL INVENTO RELATA UN SISTEMA DE RADIO MOVIL DIGITAL QUE INCLUYE UNAS ESTACIONES BASE (BM,BN) Y ESTACIONES MOVILES (MS1,MS2) CON TRANSMISORES Y RECEPTORES. EL INVENTO TAMBIEN RELATA UN METODO DE TRANSMISION DE MENSAJES DIGITALES ENTRE LAS ESTACIONES MOVILES Y LAS ESTACIONES BASE. DE ACUERDO CON EL INVENTO, AL MENOS DOS ESTACIONES TRANSMISORAS BASE (BMA,BMB,BNA,BNB) EN UNA DISTANCIA DE TRANSMISION DADAENTRE UNA Y LA OTRA SE ASIGNAN A CADA UNA DE LAS CELULAS SEGURAS (CM,CN) DENTRO DE UN AREA GEOGRAFICA RESTRINGIDA. LA ESTACION BASE TRANSMISORA QUE SE ASIGNA A LA MISMA CELULA TRANSMITE SEÑALES DE RADIO MODULADAS Y DIGITALES DENTRO DEL MISMO RANGO DE FRECUENCIA AL MENOS PARCIALMENTE SIMULTANEO A LAS ESTACIONES MOVILES DE LA CELULA. LAS SEÑALES DE RADIO DE DISTINTAS ESTACIONES TRANSMISORAS BASE ASOCIADAS CON LA MISMA CELULA SE MODULAN DIGITALMENTE CON EL MISMO MENSAJE A LAS ESTACIONES MOVILES EN LA CELULA. ESTACIONES TRANSMISORAS DE DIFERENTE BASE (9A,9B) TRANSMITEN PREFERENTEMENTE LAS SEÑALESDE RADIO DIGITALMENTE MODULADAS CON EL MISMO MENSAJE A UNA ESTACION MOVIL DADA CON EL CAMBIO DE TIEMPO DE TRANSMISION MUTUA DADO. AQUI, EL CAMBIO DEL TIEMPO DE TRANSMISION SE SELECCIONA INDIVIDUALMENTE POR CADA ESTACION MOVIL, TAL QUE LAS CORRESPONDIENTES SEÑALES DE RADIO MODULADAS DIGITALMENTE CON EL MISMO MENSAJE A UNA ESTACION MOVIL DESDE DIFERENTES ESTACIONES TRANSMISORAS LLEGAN PRACTICAMENTE AL MISMO TIEMPO A LA ESTACION MOVIL.
