Hacia la próxima generación de sistemas de Radio sobre Fibra de banda ancha: retos tecnológicos en la banda de las ondas milimétricas

in this paper, we present a review based in the most relevant scientific works of radio-over-fiber technology. the most important issues of the state-of-the-art evolution are exposed. we show a description of the main devices and the most recent experimental tests that suggest the integration between wired and wireless networks, and the convergence in heteroge-neous networks. in this review, we identify a trend toward the increase of the radiofrecuency-carrier in the millimeter-wave bands (75-100 ghz) which show that the next generation of radio-over-fiber system will operate in this band of large capacity available. the challenge consisting of reaching multi-gbps wireless transmissions in these systems very soon.
