Abstract

UN SISTEMA DE CONMUTACION DE ANTENA PARA MANEJAR SECTORES DE MUCHO TRAFICO EN UN SISTEMA DE RADIOTELEFONO CELULAR. EL SISTEMA CONMUTA LOS TRANSMISORES DE ESTACION DE BASE DE CELULA (210) A SECTORES QUE TIENEN MAS TRAFICO MOVIL DEL QUE PUEDEN MANEJAR. LOS TRANSMISORES ADICIONALES (210) AUMENTAN EL NUMERO DE FRECUENCIAS EN EL SECTOR SOBRECARGADO, PERMITIENDO CON ELLO UNA CANTIDAD MAYOR DE TRAFICO MOVIL PARA USAR LA CELULA.
