Abstract

LA INVENCION SE REFIERE A UN PROCEDIMIENTO Y UNA DISPOSICION PARA EL CONTROL DE UN EQUIPO DE RECEPCION DE RADIO. LA DISPOSICION MUESTRA UN PROCESADOR (DECT-C) CENTRAL, UN EQUIPO (RSSI-C) PARA LA MEDICION DE LA INTENSIDAD DE CAMPO DE LA SEÑAL RECIBIDA, UN GENERADOR (TH-C) DE VALOR UMBRAL ASI COMO DOS ANTENAS (A1,A2). EL PROCESADOR (DECT-C) CENTRAL EJECUTA OPERACIONES DISEÑADAS DE TAL MODO, QUE SE EJECUTAN VARIOS PROCEDIMIENTOS (P1,P2) PARA LA ACTIVACION DE UNA DE VARIAS ANTENAS (A1,A2) RECEPTORAS COMO UNA FUNCION DE LOS VALORES (RSSI1) DE INTENSIDAD DE CAMPO MEDIDOS DE LAS SEÑALES RECIBIDAS, Y, EN DEPENDENCIA DE QUE VALOR EXCEDE O CAE, SE ACORTA EL VALOR (THO) UMBRAL.
