The network traffic data cover 12,264 4G base stations and 2,159 5G base stations.

How much energy does a 5G base station use?

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.

What is the system boundary of 5G base station?

The system boundary of the CO 2 of 5G base station The civil construction of 5G base stations is typically carried out using the existing infrastructure of 4G base stations, resulting in less material input during the construction phase. The primary focus on carbon emission generation is during the use phase due to power consumption.
