Abstract

UN SISTEMA DE TRANSMISIONES APROPIADO PARA USO CON RADIOTELEFONOS PORTATILES A MANO, QUE FUNCIONAN EN MODO CELULAR, SIENDO EL TAMAÑO DE CELULA TIPICO ENTRE 500M Y 3KM DE RADIO. CADA CELULA COMPRENDE AL MENOS UNA ESTACION PRINCIPAL O BASE (10) CONECTADA AL PSTN Y UNA O MAS ESTACIONES PORTATILES SECUNDARIAS (14) QUE SON CAPACES DE TRASLADARSE DENTRO DE LA CELULA. LA TRANSMISIOPN RADIO ENTRE LAS ESTACIONES LA PUEDE INICIAR CUALQUIER ESTACION. CADA ESTACION PRINCIPAL Y SECUNDARIA TIENE MEDIOS DE TRANSMISION-RECEPCION RADIO PARA TRANSMISIONES DUPLEX DE DIVISION DE TIEMPO ENTRE LAS ESTACIONES, UN CODIFICADOR-DECODIFICADOR QUE FUNCIONA A 32KBITS/SEGUNDO O 11,4KBITS/SEGUNDO Y MEDIOS PARA TRANSMITIR LA VOZ DIGITALIZADA DE ACUERDO CON UNA ESTRUCTURA ENCUADRADA QUE COMPRENDE 3 CANALES DE CADENCIA COMPLETA O 6 CANALES DE MEDIA CADENCIA POR PORTADORAS, SIENDO MODULADA LA PORTADORA A UNA CADENCIA DE BIT DE PORTADORA DE 270.8333KBITS/SEGUNDO SUSTANCIALMENTE. EXISTE CAMBIO DE TURNO O PUESTO INTERNO Y EXTERNO, SI ES PRECISO. IGUALMENTE, SI SE NECESITA, LA ESTACION SECUNDARIA PUEDE ESTAR CONSTRUIDA PARA FUNCIONAR EN EL SISTEMA DECT ASI COMO EN EL SISTEMA ANTES DESCRITO.
