The effect of variable wake up time on the utilization of sleep modes in femtocell mobile access networks

Abstract

Femtocells are considered as an enabler for low power, high bit rate future mobile access networks. In this study, we look at them as a technology to cover an area with a high bit rate connectivity. From the evaluation it is clear that sleep modes are imperative to maximise the energy efficiency of the mobile access network. We evaluate the power reduction and wake up time of different sleep modes and apply them to the model in order to evaluate the influence of the power consumption of the mobile access network. We demonstrate that fast wake up times and low power sleep modes are essential in order to make femtocells a viable technology for mobile access networks.
