Special Issue on

Green Radio


Society has grown increasingly aware of the need to reduce CO2 emissions in order to mitigate consequential environmental effects. The primary contributors to CO2 emissions are electric power generation, transport, and manufacturing. Information and communications technology (ICT) at present contributes a nonnegligible 3% of world-wide energy consumption, which in turn causes about 2% of the world-wide CO2 emissions. The dramatic growth in internet traffic and the growing use of mobile and wireless technologies to support this are likely to increase CO2 emissions in the future unless greater energy efficiency can be achieved in networking technologies. Thus, the development of wireless networks that require lower energy consumption is desirable. In addition to this key driver of reducing CO2 emissions, the cost of energy has increased substantially and this is a significant proportion of the costs of any wireless infrastructure company. These issues have resulted in an increased interest in “green radio” networks that reduce the energy requirements for wireless communications and can thus contribute not only to goals for sustainable development, but also to the profitability of the telecommunication industry.

Although green radio can be justified in the context of energy consumption as noted above, it also can be viewed in a wider sense, such as in the optimization of spectrum usage to reduce electromagnetic radiation levels in order to enable coexistence ofmultiple wireless systems (i.e., less interference) as well as to reduced human exposure to radiation, in the recycling and reuse of ICT equipment, and in many other related contexts. In line with such objectives, the topics of this special issue to be covered include, but are not limited to:
