The rapidly increasing penetration of smart phones and the associated exponential growth in the wireless data traffic result in an increasing energy consumption and, consequently, greater carbon dioxide (CO2) emissions. However, on account of operational costs and environmental worries, this increase should be taken into consideration for future cellular networks evolution. In this paper, we study...
With the growth of cellular networks and emergence of new technologies, the power consumption of mobile communication networks has become an important and worrying topic that should be taken into consideration in any future cellular evolution. Recently, many solutions were proposed in the literature to reduce the power in cellular communications while maintaining the quality of service, in the purpose...
In this paper new architectural approaches that improve the energy efficiency of a cellular radio access network (RAN) are investigated. The aim of the paper is to characterize both the energy consumption ratio (ECR) and the energy consumption gain (ECG) of a cellular RAN when the cell size is reduced for a given user density and service area. The paper affirms that reducing the cell size reduces...
