Base station (or base radio station, BS) is – according to the International Telecommunication Union 's (ITU) Radio Regulations (RR) [1] – a " land station in the land mobile service. " A base station is called node B in 3G, eNB in LTE (4G), and gNB in 5G. Understanding how these stations function is essential for anyone engaged in the field of telecommunications or simply interested in the mechanics. . The idea of base stations is anchored in their function to provide coverage, capacity, and connectivity, hence allowing for extending the working capabilities of mobile phones and other radio gear.

Coordinating hydropower and wind power satisfies hourly operation requirement. Swedish government's target is to have 100% renewable electricity production by 2040. Currently, hydropower contributes the majority of renewable electricity generation of the country. The wind power capacity has increased significantly in the past decade.
In the recent decade, wind power capacity in Sweden has increased significantly. The electricity generation from wind power in 2009 was 2.5 TWh, which was 1.87% of the total electricity generation of the year. In 2019, it increased to 19.9 TWh, which is 12.1% of the total electricity generation.
The target wind power capacity 25,000 MW is around triple of current existing wind power capacity in Sweden. In other words, if the wind power capacity can be tripled from 2019, it is possible to reach a 100% renewable electricity generation system in Sweden.
Sweden has a wave power station outside Lysekil run by Uppsala University. The wave energy research group at Uppsala University study and develop all different aspects of wave energy, ranging from power systems and generators, to hydrodynamical modelling, and environmental impact of wave energy parks.

Therefore, low-carbon upgrades to communication base stations can effectively improve the economics of local energy use while reducing local environmental pollution and gaining public health benefits. For this research, we recommend further in-depth exploration in three areas for the future.
Strategies such as applying solar energy generation facilities in base stations to replace part of the grid electricity or implementing active deep sleep in communication base stations to optimize energy management 7,8,9,10 have been applied to reduce the use of grid-supplied energy and lower the operating costs of communication systems.

The power consumption of the base station is directly related to the power, and the size of the power consumption of the base station mainly depends on the transmit power of the base station, which in turn depends on the communication distance of the base station. Recognizing this, Mobile Network Operators are actively prioritizing EE for both network maintenance and environmental stewardship in future cellular networks. . The explosive growth of mobile data traffic has resulted in a significant increase in the energy consumption of 5G base stations (BSs).

Base stations represent the main contributor to the energy consumption of a mobile cellular network. Since traffic load in mobile networks significantly varies during a working or weekend day, it is important to quantify the influence of these variations on the base station power consumption.
The base station is the primary source of energy consumption in radio access network architecture, and hence the reduction of energy consumption of the base stations can improve the overall energy efficiency of the radio access network that has received much attention (e.g., , , ).
Is there a direct relationship between base station traffic load and power consumption?
The real data in terms of the power consumption and traffic load have been obtained from continuous measurements performed on a fully operated base station site. Measurements show the existence of a direct relationship between base station traffic load and power consumption.
So when the inter-cell distance is too large, it is necessary to increase the distance between cells, thus reducing the power consumption of the base station. In the actual network, in order to reduce the energy loss caused by frequent switching, the following two methods can usually be used: increase the distance between cells.
