5G infrastructure power supply design
Discover the factors that telecoms organizations need to consider for 5G infrastructure power design in the network core and cloud.
As core components, 5G base station chips must meet the following key technical requirements: 1.High Spectrum Efficiency and Large Bandwidth Support 5G networks use a broader range of spectrum resources, particularly the millimeter-wave bands (24 GHz and above).
From the trends and challenges mentioned above, we can derive three key general requirements for the 5G infrastructure: • High efficiency. Achieving high efficiency is the best way to reduce heat dissipation (due to high power consumption compared to 4G) and operational expenses (OPEX). • Re-use of existing infrastructure.
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.
The goal of 5G networks is to achieve ultra-low latency (as low as 1 ms) and large-scale device connections (up to a million devices per square kilometer). Base station chips must support high-density small cell deployments, meet the massive device access demand, and emphasize high processing speeds and scheduling capability.
