ABSTRACT

The main objective of green wireless research is to reduce the carbon footprint and energy consumption of information technology (IT) industry. There are more than 4 billion cell-phones in the world [1], and wireless devices and equipments consume 9% of the total energy of IT, i.e., as much as 6.1 TWh/year [2]. Future wireless systems such as 3GPP-LTE or WiMAX2 are evolving to support broadband services that demand a higher capacity than can be provided by today’s wireless networks. In most cases, this is achieved at the expense of higher energy consumption and severe impact on the environment.
