The currently growing demand for Information and Communication Technologies (ICTs), and multimedia services, is generating a fast expansion of digital traffic. To fulfill such demands, new generation access architectures have been proposed that try to integrate and optimize available technologies. Besides allowing new services to emerge, such architectures also offer a great opportunity to develop new methods that try to increase energy efficiency by proper equipment management and sharing of resources. Here, the authors focus on energy saving in Fibre-Wireless (Fi-Wi) access networks, which provide high bandwidth and ubiquity to future multimedia services and applications.
