The contribution of the information and communication technology (ICT) sector to global energy consumption has increased considerably in the last decade along with its growing relevance in the overall economy. This trend is expected to continue with the apparently ever greater use of these technologies. One of its main causes is the broadband data traffic generated by the use of telecommunication networks, in particular through existing and upcoming wireless systems. In response to user demand, the telecom industry is starting the deployment of the fourth generation (4G) of mobile communications. However, energy consumption has generally been absent from the debate on 4G deployment, despite its potential impact on both operating expenses and sustainability. This paper forecasts the energy consumption in 4G networks through the development of a baseline model to assess the energy consumption and details its evolution over the deployment period. This model combines three elements: the penetration of wireless broadband technologies, the traffic per mobile user, and the energy consumption profile of each active device in the network. Conclusions are presented for the energy consumption and how it is affected by variations in the network design parameters. A detailed case study of Spain is considered for calculation purposes, although the model and the conclusions can easily be extended to similar countries. | |
