Mobile broadband access is experiencing an
impressive market growth, the number of mobile
broadband subscribers being expected to be
about five billion by 2016. This growth is associated
to an increased energy consumption of
mobile networks, therefore, increasing the carbon
footprint. Even considering that Long Term
Evolution (LTE) may replace legacy technologies
this will only occur several years after its full
commercial deployment, hence, huge efforts
needs to be made in order to allow a proper
LTE network design to improve energy efficiency
as much as possible.
