How many 5G base stations are built in China?

As 5G serves as the foundation for the construction of new infrastructure, China, as the world leader in 5G base station construction, has already built over 1.4 million 5G base stations in 2021 alone. In the same year, 5G base stations in China produced approximately 49.2 million tons of CO 2 eq.

Do 5G base stations need more base stations?

Consequently, deploying more base stations is necessary for 5G base stations to cover the same area. Macro and micro base stations are currently being deployed for 5G network. The base station is categorized into micro base station, macro base station, and sub-system based on the coverage range.

How can wireless access networks reduce energy consumption?

The wireless access network incurs the most significant energy loss, with base station loss being the largest contributor. Consequently, energy-saving and emission reduction measures should primarily focus on reducing the resource demand of base stations (Liu, 2018).

How much power does a micro base station use?

The power consumption of a single macro base station is approximately 5 kW, whereas a Pico Cell requires only about 10 W (Bolla et al., 2012; Deruyck et al., 2014; Hu & Yi, 2014). Deploying multiple micro base stations to cover the blind spots of a macro base station will reduce power consumption during operation, thereby reducing carbon emissions.
