6 FAQs about [Analysis of China s 5G base station energy-saving path]

How much energy does a 5G base station use?

China Mobile’s measurement report 9 indicates that the energy consumption of a 5G base station is 4.3 kWh, which is four times that of a 4G base station at 1.1 kWh. One 5G base station is estimated to produce 30 t of carbon emissions in one year of operation 10.

How can we improve the energy eficiency 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.

How much carbon does 5G emit in China in 2021?

The results indicate that, due to the high carbon emissions resulting from the new infrastructure, the carbon emissions of 5G base stations in China in 2021 amounted to 49.2 MtCO 2 eq.

Does China have a 5G network?

Given that China currently has the largest 5G network in the world (∼1.53 million base stations by the end of 2021, Table S1) and that base station number was projected by up to 6–8 million by 2030 (CCID Consulting, 2020), concerns are being expressed regarding 5G mobile networks' environmental effects and sustainability.

How does the 5G network affect carbon efficiency?

Carbon efficiency, the amount of network traffic that can be delivered for one unit of carbon emissions, decreased from 2.98 TB per tCO 2 to 2.08 TB per tCO 2 (Fig. 1c). After the launch of the 5G network, there was a large and rapid increase in carbon emissions.

Could 5G help achieve China's Carbon Peak target?

In the case of a 5G low power load (Fig. 5 b), the fraction reduces to 0.13 %, suggesting that power load from switching 4G to a 5G network could reduce about 6 % of CO 2 emission subject to the nation's carbon peak scenario. In light of this, replacing the 4G with a 5G network could help achieve China's carbon peak target.
