The beyond3G vision envisages higher data rates and multi standard radio interfaces to provide all users with a continuous seamless connection at any place, anytime and on any system. Therefore the large number of multimode devices coupled with the surge in power requirements for future emerging handsets raises significant challenges in terms of reducing the energy consumptions, and reducing the amount of electromagnetic radiations in order to minimize the global impact of CO2 emissions. In fact, current state-of-the-art of multi-standard devices has high power requirements for maintaining two or more radio interfaces. It is envisaged that a dramatic increase in the energy consumptions of 4G devices will make active cooling a necessity.
Indeed, from the manufacturer’s perspective, the issue of power consumptions is becoming a key concern since there is a continuously growing gap between the energy required by emerging radio systems and what can be actually achieved by:
i) the evolutions on battery technology;
ii) the progresses on scaling and circuit design;
iii) the design of novel system level architectures; and
iv) the development of novel thermal and cooling techniques.
Therefore, one of the biggest challenges for the future wireless systems is the need to limit the energy consumptions of battery-powered devices, with the aim to prolong their operational time and avoid active cooling. Without new approaches for energy saving, there is a significant threat that the 4G mobile users will be searching for power outlets rather than for network access, thus being restricted to stay in a single position and losing their mobile capabilities.
In typical mobile terminals for cellular systems up to half of the power consumptions come from communications-related functions, such as baseband processing, RF, and connectivity functions. Therefore any reduction in the power consumptions of all these functionalities will have a substantial impact on the battery lifetime.
