Abstract

METODO DE TRANSMITIR INFORMACION DE LLAMADA EN UN SISTEMA TELEFONICO MOVIL DE CORTO ALCANCE Y UNIDAD DE RADIO PARA LLEVAR A LA PRACTICA EL METODO, ENTRE UNA ESTACION BASE DE RADIO (FS) Y UNO O MAS RADIOTELEFONOS PORTATILES (PS) QUE ESTAN A CORTA DISTANCIA D LA ESTACION BASE. LA TRANSMISION DESDE UNA ESTACION DE BASE (FS) A UN RADIOTELEFONO (PS) OCUPA INTERVALOS DE TIEMPO (CH1 - CH16) DENTRO DE UNA MITAD DE UN INTERVALO DE CUADRO Y LA RECEPCION OCUPA INTERVALOS DE TIEMPO DENTRO DE LA OTRA MITAD. CUANDO UN CANAL OCUPA UN INTERVALO DE TIEMPO (CH1) PARA TRANSMISION/RECEPCION EN UNA FRECUENCIA PORTADORA DADA (FSI1), LAS RESTANTES FRECUENCIAS PORTADORAS ESTAN BLOQUEADAS PRECISAMENTE PARA ESTE INTERVALO DE TIEMPO Y DEBERA USARSE UN SEGUNDO INTERVALO DE TIEMPO CON LA MISMA (FSI1) O UNA SEGUNDA FRECUENCIA PORTADORA (FSI1 - FSI4), PARA UN SEGUNDO CANAL. LA UNIDAD DE RADIO PARA LLEVAR EL METODO A LA PRACTICA COMPRENDE UNA UNIDAD TRANSMISORA (1) DE CONVERSACION DE LLAMADA AL TELEFONO MOVIL, UNA UNIDADRECEPTORA (2) DE INFORMACION DE LLAMADA DEL TELEFONO MOVIL, UNA UNIDAD ANTENA (4) Y UN SELECTOR (5) DE CANALES JUNTO CON UNA UNIDAD DE SINCRONIZACION (6).
