Final draft of deliverable D.WG3-02-Smart Energy Saving of
While 5G offers much faster speed, massive connections and much lower latency, and would enable a much bigger variety of new applications for both people''s lives and vertical industries,
Several techniques have been deployed to reduce the energy consumption of the base station in what is called a green base station. This paper presents an insight into these approaches and highlights key challenges and potential research directions.
This proliferation of BSs has resulted in consequential increase in energy consumption and Green House Gases (GHGs) emission. Several techniques have been deployed to reduce the energy consumption of the base station in what is called a green base station.
This study presents an overview of sustainable and green cellular base stations (BSs), which account for most of the energy consumed in cellular networks. We review the architecture of the BS and the power consumption model, and then summarize the trends in green cellular network research over the past decade.
There are two main methods of base station energy saving, including hardware and software.

In 2011, it was estimated that there were about 4 million base stations globally, each consuming an average of 25 MWh per year [3]. Base station sites are the most energy-hungry parts

Energy Consumption The cellular Radio Base Station (RBS) is the most energy–intensive component in a 3G mobile network. A typical 3G RBS consumes about 500 W with
Base station equipment accounts for 50% of the total energy consumption, followed by air conditioning equipment, which consumes 40%.
How much energy can be saved by upgrading base station equipment? Upgrades to modern, energy-efficient base station hardware can save between 20% and 40% of total energy
The impact of the Base Stations comes from the combination of the power consumption of the equipment itself (up to 1500 Watts for a nowadays macro base station) multiplied by the
We review the architecture of the BS and the power consumption model, and then summarize the trends in green cellular network research over the past decade.
Through these interventions, China Mobile added 467,000 5G base stations while achieving a 2% reduction in overall base station energy consumption in 2024, demonstrating the
In the 5G era, the maximum energy consumption of a 64T64R active antenna unit (AAU) will be an estimated 1 to 1.4 kW to 2 kW for a baseband unit (BBU). Base stations with multiple
