Sao Tome 5g base station manufacturer energy

The network traffic data were collected from China Mobile. We carried out a city-level measurement in Nanchang and collected fine-grained records on the network traffic of all 4G and 5G base stations for one week in May 2022. The network traffic data cover 12,264 4G base stations and 2,159 5G base stations.

China Mobile's measurement report9 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 operation10.

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 operation10. Thus, 5G networks in China are roughly estimated to produce over 60 Mt of carbon emissions annually at the national level11.

In contrast, the western provincial regions (such as Qinghai and Tibet) have fewer 5G base stations and produce fewer additional carbon emissions. The wealthier eastern provincial regions also have higher additional carbon emissions per unit area than the less developed western areas (Fig. 1f).

We reveal a carbon eficiency trap of 5G mobile networks leading to additional carbon emissions of 23.82 ± 1.07 Mt in China, caused by the spatiotemporal misalignment between cellular trafic and energy consumption in mobile networks.

This Technical Report explores how network energy saving technologies, such as carrier shutdown, channel shutdown, symbol shutdown etc., that have emerged since the 4G era, can be leveraged to mitigate 5G energy consumption.
