How big is the battery of the green communication base station

What is a green base station?

The Green Base Station which is introduced is equipped with the regenerative energy sources wind power and photo-voltaic energy to reduce the power consumption taken out of the public grid to a minimum, whenever sunlight or wind is present.

Are green cellular base stations sustainable?

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.

How many green cellular Bs are there?

GSMA predicted that the number of green BSs would increase to 389,800 by 2020 [ 8 ], which reflects the growing awareness of cellular network operators about the significant economic and ecological influence of their networks in the coming years. Figure 10. Worldwide deployment of green cellular BSs [ 107 ].

Are cellular network operators moving towards green cellular BS?

Figure 10 reveals that many cellular network operators in the world have still not shifted toward green cellular BS. Most of these operators are located in developing countries with limited electricity supply and unreliable electric grids. The financial issues in these countries must be investigated further. 4.5.

How much does a PV/electrical grid cost for GSM BS?

Hossam et al. [ 132] designed four hybrid RESs for GSM BSs in Cairo, Egypt and proposed the use of a PV/electrical grid in urban areas; PV, PV/DG, and PV/DG in remote areas; and DG on cloudy days. The energy costs of PV/electrical grid, PV/DG (on cloudy days), PV, and PV/DG reach as low as $ 0.1, $ 0.21, $ 0.29 and $ 0.31/kWh, respectively.

How do cellular network operators shift to green practices?

Cellular network operators attempt to shift toward green practices using two main approaches. The first approach uses energy-efficient hardware to reduce the energy consumption of BSs at the equipment level and adopts economic power sources to feed these stations.
