Abstract
LA INVENCION SE REFIERE A LOS INTERCAMBIOS DE DATOS POR ONDAS POR HIPERFRECUENCIAS ENTRE UNA ESTACION FIJA (2) O LECTOR, Y UNA ESTACION MOVIL (1) O BADGE. PARA AUMENTAR LA SENSIBILIDAD DEL SISTEMA, Y SU ALCANCE EL MODEM (3) DEL BADGE (1) COMPRENDE UN OSCILADOR. EL MISMO TRANSISTOR (11) FUNCIONA, BAJO UNA PRIMERA POLARIZACION COMO DETECTOR DE LA ONDA EMITIDA POR EL LECTOR, Y DESMODULA ESTA ONDA, DESPUES, BAJO UNA SEGUNDA POLARIZACION, FUNCIONA COMO OSCILADOR Y MODULA LA RESPUESTA EMITIDA POR EL BADGE (1). APLICACION EN LOS INTERCAMBIOS DE DATOS A DISTANCIA.
