The power consumption of mobile devices (MDs) has been increasing dramatically since more functions and bigger screens are adopted in the latest MDs. To extend the usage time of MDs and improve customer satisfaction levels, this research study, for the first time, studies the influence of different deployment strategies of a few low-power base stations (BSs) to reduce the power consumption of a large number of MDs. For both microcell and picocell scenarios, the authors’ analyse the power reductions at the MD side with the deployment of a low-power BS. The optimum low-power cell radius is derived for achieving the maximum MDs power reduction. The tradeoff relationships between MD power reduction and the key parameters of low-power BSs are investigated and discussed. It is shown that authors’ proposed method can achieve about 18% power reduction for microcell MDs.
