What is a green base station?

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.

Can a green base station reduce energy consumption?

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.

Are cellular base stations sustainable?

Multiple requests from the same IP address are counted as one view. Energy efficiency and renewable energy are the main pillars of sustainability and environmental compatibility. This study presents an overview of sustainable and green cellular base stations (BSs), which account for most of the energy consumed in cellular networks.

Should base stations always be connected to the power grid?

Several strategies have been mentioned in the literature to overcome this issue. Such as, for continuous energy supply, base stations should always remain connected to the power grid. However, this strategy is not environmentally friendly and could also result in higher energy costs.

How do cellular base stations reshape non-uniform energy supplies and energy demands?

These strategies use bidirectional energy flow to reshape the non-uniform energy supplies and energy demands over mobile networks. A joint spectrum and energy sharing method is presented in Guo et al. (2014b) between cellular base stations to minimize the OPEX.

Why is the energy consumption of a base station different at different times?

Since the energy consumption of the base station relies on the traffic load, therefore, it may be different at different time instants. The renewable energy utilization is optimized by balancing power consumption between base stations with the availability of RE to support the traffic demand from all users.
