Comparison of Power Consumption Models for 5G Cellular
Power consumption models for base stations are briefly discussed as part of the development of a model for life cycle assessment. An overview of relevant base station power
To improve the energy eficiency of 5G networks, it is imperative to develop sophisticated models that accurately reflect the influence of base station (BS) attributes and operational conditions on energy usage.
This restricts the potential use of the power models, as their validity and accuracy remain unclear. Future work includes the further development of the power consumption models to form a unified evaluation framework that enables the quantification and optimization of energy consumption and energy efficiency of 5G networks.
The simulation results show that 700 MHz and 26 GHz will play an important role in 5G deployment in the UK, which allow base stations to meet short-term and long-term data traffic demands respectively.
Nevertheless, the overall energy usage by 5G base stations needs to be reduced as it will account for approximately 2%−3% of total UK's energy consumption in 2030. Energy costs account for 19% - 23% of RAN OpEx, which will seriously affect MNOs' mainstream profits.
