What are the power delivery challenges with 5G to
It''s been estimated that base station resources are generally unused 75 – 90% of the time, even on high-load networks. The base
However, this technological leap comes with a substantial increase in energy consumption. Compared to its predecessor, the fourth-generation (4G) network, the energy consumption of the 5G network is approximately three times higher .
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.
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.
The further completion of the map of power models (Fig. 2) and systematization of their features as well as the comparison is also part of the future work. Lastly, the aspects of computing (network function virtualization) and functional split options of the RAN need to be considered for 5G networks as well.
