Modelling the energy efficiency of Heterogeneous Cloud Radio Access Networks

Cellular network performance is measured by its spectral and energy efficiency, with power consumption an important key to success for the upcoming heterogeneous (HetNet) communication system generations. The proposed models presented in this paper, component, linear, and parameterized power models, analyse and evaluate the power consumption participants in both Cloud Radio Access Network (C-RAN) and the State of the art (SotA) Base stations i.e.(Macro, Pico, Femto) when all participants interface in the area of interest, collectively called Heterogeneous-Cloud Radio Access Network (H-CRAN), in a proposal to enhance both energy and spectral efficiencies. Results showed that a C-RAN network reduced the cooling power consumption to about 87%, which reduced the overall power consumption compared to MBS deployment. Finally, H-CRAN cooling and total power consumption is evaluated by integrating C-RAN and the SotA BSs power consumption models.
