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 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.
Are solar-powered BSS a cost-effective option for cellular network operators?
Therefore, the use of solar-powered BSs is a cost-effective option for cellular network operators. In June , the LG Uplus operator tested a solar-powered LTE BS with an energy storage system (batteries) that could operate between 24 h and 48 h even on cloudy days.
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.
What is a green cellular network?
Most studies on green cellular networks have adopted ideal models. As its name implies, the green communication initiative aims to make cellular networks “greener” by reducing their power consumption using the aforementioned approaches.
Can solar power be used for off-grid telecommunications?
The potential of using renewable energy was explored in [ 115 ], which found that solar power is the most suitable alternative power source for off-grid telecommunications systems and for grid areas that frequently experience power failure. A feasibility study conducted on a solar PV system in grid-connected BS sites was presented in [ 116 ].
