Abstract

Power consumption of mobile devices is a great concern in the current mobile communication systems. Recent analysis by manufacturers and network operators has shown that current wireless networks are not very energy efficient. Power consumption is directly related to the coverage area of the base station. So in this chapter, the authors analyze and compare the total power consumption, power consumption per covered area and ranges of the macrocell, microcell and femtocell base stations for Mobile WiMAX, fixed WiMAX, UMTS, HSPA, LTE for 1x1 SISO systems and mobile WiMAX, HSPA, and LTE will be considered for 2x2 MIMO system. The numerical example will be illustrated with help of simulation results. This chapter enables the reader for knowledge of power consumption in existing wireless access networks technology with current and future trends of research.

Background

The power consumption and energy efficiency of telecommunications networks become more and more important. For wireless access networks, most studies focus on energy-efficient deployments of wireless access networks. These studies shows that the user try to reduce the number of base stations in the network by switching them off during periods of low traffic which is a very promising method for energy savings. These studies in combination with a realistic power consumption model for base stations will enable to quantify the actual power savings in the network.
