There is a rising concern for the energy consumption of communication networks. It has been estimated that the global ICT energy consumption amounts to 7% of the entire electricity production. The access segment is of particular importance as it amounts to more than half of the total energy consumption associated with communication networks. These figures hold for current traffic loads, while projections show that by the year 2015 capacity requirements will be 25-30 times larger than today, with an expectation that by the year 2020 we will witness a thousand-folds increase in traffic.

Passive Optical Networks (PONs), long reach PONs, and point-to-point fiber access solutions are becoming an energy efficient and attractive alternative for the wired access side. With the rapidly increasing bandwidth demands in mobile networks, and with the evolution towards more dense or heterogeneous networks to cater for this increasing capacity, it is of particular importance to understand means of reducing power in next-generation mobile wireless networks as well, by way of deployment of small cells, and energy efficient multiple antennas transmissions. There are also indications that the backhaul contribution to power consumption will grow as mobile networks become more dense, potentially nullifying the benefits of energy efficient wireless access strategies. This calls for a holistic understanding of the energy optimization process of entire broadband access segment as a whole where the backhaul contribution can no longer be neglected.
