A Study of Densification Management Using Energy Efficient Femto-Cloud Based 5G Mobile Network

摘要

Energy efficiency in wireless communication becomes essential. Power optimization of mobile radio systems has gained attention of network operators because energy costs make up a huge part of operational expenditure. In this regard, deployments of low power small cell base stations considerably raise the challenge of energy-efficient cellular networks. Network densification refers to densification over space, for example dense small cell deployment like picocell, femtocell, and frequency utilization of larger segments of radio spectrum in dissimilar bands. In this article we have illustrated the cause factors of densification and described its effects. The deployment layouts of different base stations are studied and compared with conventional macro-femtocell systems from the perspective of area power consumption and signal-to-interference-plus-noise-ratio.
