Can a 5G base station promote green development of mobile communication facilities?
However, a significant reduction of ca. 42.8% can be achieved by optimizing the power structure and base station layout strategy and reducing equipment power consumption. Overall, this study provides a clear approach to assess the environmental impact of the 5G base station and will promote the green development of mobile communication facilities.
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.
Are 5G base stations based on a 4G base station?
At present, most 5G base stations are upgraded or constructed based on 4G base stations in China and ca. 97% of the towers are constructed based on existing site resources (Meng, ). The installation of AAU adopts poles or towers according to a certain proportion.
What is 5G base station equipment architecture?
The 5G base station equipment architecture mainly adopts the BBU + AAU method. The BBU is the baseband part and can be further divided into two logical network elements, CU and DU. The CU handles the protocol stack functions above the PDCP layer of the wireless network, while the DU handles radio protocol functions below the PDCP layer.
How does a 5G base station consume energy?
In terms of energy consumption, 5G base stations require continuous operation and stability, which leads to significant electricity consumption (Guo et al., 2022a). This power is mainly supplied by transmission equipment and auxiliary equipment, such as transformers, UPS power supplies, and cooling equipment.
How many 5G base stations are built in China?
Emission reduction potential and model sharing In , China began to build 5G base stations and has built over 113,000. Construction of 5G base stations accelerated in and a total of 718,800 base stations were built, resulting in a sharp increase in carbon emissions.
