Abstract
LA INVENCION REFIERE A UN RADIOSISTEMA CELULAR Y A UN METODO PARA TRANSMITIR CANALES PILOTO EN UNA RED DE RADIO CELURAR, QUE COMPRENDE EN CADA CELULA AL MENOS UNA ESTACION BASE (550) QUE SE COMUNICA CON ESTACIONES MOVILES (552,554) LOCALIZADAS EN SU AREA, CUYAS ESTACIONES BASE TRANSMITEN UNA SEÑAL DE DATOS EN LA DIRECCION DE SEÑAL DE BAJADA USANDO DIRECCIONES DE TRANSMISION QUE CAMBIAN EN EL TIEMPO Y QUE TRANSMITEN INFORMACION SOBRE EL SISTEMA A LAS ESTACIONES MOVILES EN CANALES DE CONTROL. PARA PERMITIR USAR TAN EFICAZMENTE COMO SEA POSIBLE LOS CANALES PILOTO, LAS ESTACIONES DE BASE TRANSMITEN AL MENOS UN PRIMER CANAL PILOTO CON UN PATRON DE RADIACION PREDETERMINADO (560), QUE DETERMINA EL AREA DE COBERTURA DE LA CELULA, Y SEGUNDOS CANALES PILOTO EN LAS DIRECCIONES DE TRANSMISION (556,558) QUE CAMBIAN EN EL TIEMPO.
