Abstract

UN SISTEMA DE COMUNICACIONES TIENE UN CENTRO BASE CON TRANSCEPTORES 15 DE RADIO PARA PROPORCIONAR UN NUMERO DE ENLACES DE COMUNICACIONES DE RADIOFRECUENCIAS (RF) Y UNA PLURALIDAD DE ACCESOS 1 DE RADIO A TRAVES DE LOS CUALES SE PUEDEN TRANSMITIR Y RECIBIR SEÑALES DE RF POR EL AIRE. UNA RED (2, 4) DE FIBRAS OPRICAS INTERCONECTA LOS TRANSCEPTORES 15 DE RF Y LOS ACCESOS 1 DE RADIO FIJOS, Y ENVIA LAS SEÑALES DE RF MEDIANTE SEÑALES OPTICAS. SE DISPONE DE UNA PLURALIDAD DE INTERFACES RADIO/OPTICOS MEDIANTE LOS CUALES LAS SEÑALES DE RF PUEDEN MODULARSE SOBRE, Y DESMODULARSE DESDE, UNA O MAS SEÑALES OPTICAS, ENTRE LOS TRANSCEPTORES DE RF Y LA RED DE FIBRAS OPTICAS, Y ENTRE LA RED DE FIBRAS OPTICAS Y LOS ACCESOS DE RADIO FIJOS. UN CONMUTADOR 13 MATRIZ INTERCONECTA SELECTIVAMENTE LOS TRANSCEPTORES Y LOS ACCESOS DE RADIO A TRAVES DE LA RED DE FIBRAS OPTICAS.
