Abstract:
The environmental and energy efficiency issues became more obvious to a larger audience in the last decade and recently several ambitious initiatives were launched worldwide to tackle these issues. Recently, increasing maturity of mobile technology in combination with the growing amount of equipment deployed each year has woken up the need of innovating in the field of energy efficient communications. In the last decade telecommunication has experienced a tremendous success causing proliferation and demand for ubiquitous heterogeneous broadband mobile wireless communications. Up to now, innovation has mainly targeted to improve wireless networks coverage and capacity while meeting the QoS for users admitted in the system. Nowadays, the number of mobile subscribers equals more than half the global population. Forecast on telecommunication market assume an increase in subscribers, per subscriber’s data rate and, the roll out of additional base stations for next generation mobile networks. The undesired consequence is the growth of wireless network’s energy consumption which will cause an increase of the global carbon dioxide (CO2) emissions and, impose more and more challenging operational cost for operators. Communication energy efficiency represents indeed an alarming bottleneck in the telecommunication growth paradigm. The home environment is also a challenge for energy efficiency, as fixed broadband becomes pervasive and services proliferate on a variety of boxes linked together by a plurality of technologies. Optimization at the device level as well as a system approach becomes necessary to deliver service continuity while reducing the overall energy consumes by the home LAN.
