This paper presents the analytical models of power consumption in macrocell, microcell,
picocell and femtocell based networks. Five case studies are presented in this paper where …

The growing energy consumption driven by dramatic increases in the number of users and
data usage becomes the key issue for operators in meeting demands on cost reduction and …

In wireless communications micro cells are potentially more energy efficient than
conventional macro cells due to the high path loss exponent. Also, heterogeneous …

In this paper, the energy efficiency of a femtocell base station is investigated and compared
for various bit rates and for three different wireless technologies namely, mobile WiMAX …

Energy efficiency in cellular networks is a growing concern for cellular operators to not only
maintain profitability, but also to reduce the overall environment effects. This emerging trend …

In mobile technologies two trends are competing. On the one hand, the mobile access
network requires optimisation in energy consumption. On the other hand, data volumes and …

In the strive for lessening of the environmental impact of the information and communication
industry, energy consumption of communication networks has recently received increased …

Energy efficiency is becoming a very important issue in modern wireless communication
systems. At the same time, maintaining QoS is also critical when trying to reduce power …

In this paper, we investigate how femtocells can make conventional cellular networks
greener. We present an energy consumption modeling framework to evaluate total energy …

Rising energy costs and the recent international focus on climate change issues has
resulted in a high interest in improving the energy efficiency in the telecommunications …
