Contribution to energy consumption modelling and forecast in next generation access networks

Research Areas
  • Engineering

The contribution from the information and communications technology (ICT) sector to global energy consumption has considerably increased in the last decade, along with its growing relevance to the overall economy. This trend will continue due to the seemingly ever greater use of these technologies. One of the primary ingredients is broadband data traffic generated by the usage of telecommunication networks. In fact, as a response to user demands, the telecom industry is initiating the deployment of next generation networks (NGNs). However, energy consumption is mostly absent from the debate on these deployments, in spite of the potential impact this could have on both expenses and sustainability. This work addresses the forecast of energy consumption in the access part of NGNs by modelling the combined effect of the deployment of different ultra-broadband technologies, the evolution of traffic per user, and the energy consumption in each of the network and user devices. Conclusions are presented on the levels of energy consumption, their cost, and the impact of different network design parameters. The effect of technological developments, techno-economic and policy decisions on energy consumption is highlighted. Practical figures and comparisons across technologies are provided. For calculations, the work considers in detail the case of Spain, although the model and conclusions can be easily extended to similar countries.
