Abstract
ESTA INVENCION SE REFIERE A UN SISTEMA DE TELEFONIA MOVIL DISEÑADO PARA SER UTILIZADO POR SUSCRIPTORES EN UN MEDIO EXTERIOR, POR EJEMPLO EN COCHES, MIENTRAS QUE, AL MISMO TIEMPO, TAMBIEN TIENE CAPACIDAD PARA SER UTILIZADO POR SUSCRIPTORES LOCALIZADOS EN UN MEDIO INTERIOR, POR EJEMPLO UN EDIFICIO CON ALTA DENSIDAD DE TRAFICO, Y EFECTUAR TRANSMISIONES LIBRES DE INTERFERENCIAS. LAS SEÑALES DE TRANSMISION ENTRE ESTACIONES MOVILES (MS, MSI) Y LAS ESTACIONES BASE (BS1, BSI) SE EFECTUA POR ONDAS DE RADIO POR MEDIO DE LA PRIMERA FASE DEL SISTEMA, DISEÑADO PARA TRAFICO TELEFONICO VIA TELEFONO DE COCHES, Y CON ONDAS LUMINOSAS, EN AREAS CERCANAS A LAS ESTACIONES MOVILES (MSI), MEDIANTE EL SISTEMA DE SEGUNDA FASE (6), DISEÑADO PARA EL INTERIOR DE EDIFICIOS. LAS SEÑALES DE TRANSMISION CON ONDAS LUMINOSAS TAMBIEN SE PUEDE EFECTUAR EN AREAS QUE CONTIENEN APARATOS ELECTRONICOS, QUE SEAN SENSIBLES A LAS INTERFERENCIAS DE RADIO, COMO EN HOSPITALES O EN AREAS CON FUERTES INTERFERENCIAS A LAS ONDAS DE RADIO DONDE NO SE PUEDEN TRANSMITIR LAS SEÑALES POR RADIO. CIERTAS ESTACIONES MOVILES SON CAPACES DE COMBINAR LAS TRANSMISIONES CON ONDAS DE RADIO Y TRANSMISIONES CON SEÑALES DE LUZ, LO QUE PERMITE A ESTAS ESTACIONES EL SER UTILIZADAS POR SISTEMAS CON AMBAS FASES (7, 6).
