Abstract

Un sistema de localizacion de dos vías utiliza cuatro frecuencias locales para transmisiones entre unidades localizadoras (22) y una estacion de control central (20). Una primera frecuencia local (f1) lleva un reloj local; una segunda frecuencia local (f2) lleva paquetes de comunicaciones desde la estacion de control central hasta las unidades localizadoras; una tercera frecuencia local (f3) lleva paquetes de comunicaciones desde las unidades localizadoras hasta la estacion de control central; y una cuarta frecuencia local (f4) lleva una señal de estado o de peticion desde las unidades localizadoras (22) hasta la estacion de control central (20). Las transmisiones sobre la cuarta frecuencia local (f4) están de acuerdo con una asignacion de ranura de division de tiempo entre las unidades localizadoras que tienen acceso a la estacion de control central (20). Para un sistema de localizacion de dos vías que tiene una pluralidad de estaciones de control central (420x), que dan servicio a una pluralidad correspondiente de células, se utilizan un total de ocho frecuencias dentro de cualquier célula. Cuatro de las frecuencias utilizadas son las frecuencias locales (f1-f4) [que pueden diferir de célula a célula], y cuatro de las frecuencias utilizadas son frecuencias comunes de más baja potencia o frecuencias de conmutacion (C1-C4), las cuales se utilizan para conmutar o distribuir una unidad localizadora (422) que viaje desde una célula hasta otra. La figura más representativa de la invencion es la numero 1.
