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, HSPA, and LTE. A power consumption model is proposed and applied in a network deployment tool to develop energy-efficient femtocell networks. Furthermore, it is investigated to what extent the introduction of sleep modes can reduce the power consumption in femtocell networks. Reductions of 24% are obtained when sleep modes are introduced into the network.
