An investigation of energy efficiency in 5G wireless networks

In next generation wireless networks along with the overwhelming demand of high data rate and network capacity, the user demands ubiquitous connectivity with the network. In order to fulfill the demand of anywhere at any time data services, the network operators have to install more and more base stations that eventually leads towards high power consumption. For this, the potential solution is derived from 5G network that proposes a heterogeneous environment of wireless access networks. More particularly, deployment of Femto and Pico cell under the umbrella of Macro cell base stations (BS). Such networking strategy will result high network capacity and energy efficiency along with better network coverage. In this article, an analysis of energy efficiency has been carried out by using two-tier and three tier network configurations. The simulation results demonstrate that rational deployment of small cells improves the energy efficiency of wireless network.
