Abstract
SISTEMA DE COMUNICACION ENTRE ESTACIONES FIJAS POR RADIO. COMPRENDE ESTACIONES FIJAS (FS) Y ESTACIONES MOVILES (FM) QUE PUEDEN COMUNICAR CON LAS ESTACIONES FIJAS POR RADIO, EN DONDE LAS ESTACIONES FIJAS ESTAN AGRUPADAS EN CELULAS CONTROLADAS, CADA UNA POR UNA ESTACION DE CONTROL (LS), EN DONDE, TODAS, O PARTE DE LAS ESTACIONES DE CONTROL CONTIENEN UNA POSIBILIDAD DE INTERFAZ (U) QUE PROPORCIONA LA CONEXION A UNA RED TELEFONICA AUTOMATICA; DONDE PARTE DE LAS ESTACIONES DE CONTROL (LS) TIENEN VIAS DE TRANSMISION ADICIONALES CERRADAS CONECTADAS A LA MISMA ESTACION DE CONTROL (LS); Y DONDE TODAS O PARTE DE LAS ESTACIONES FIJAS (FS) ESTAN CONECTADAS A LAS VIAS DE TRANSMISION. ES UTIL EN CASO DE FALLOS EN LA VIA DE TRANSMISION.
