Abstract:
Cellular base stations consume a lot of energy since it requires a 24-h continuous power supply which results in an increased operational expenditure (OPEX) and environmental pollution. This OPEX and harmful effects should be decreased to achieve sustainable and profitable businesses for mobile operators. In this case, a hybrid renewable energy solution like solar energy and wind power is proposed which will be used to power these cellular base stations. Solar energy can power daytime and wind power can power both day and nighttime. Thus, together they can supply power efficiently. When a particular base station fails, or its workload is high then its workload can be transferred to another base station for a certain amount of period. Sometimes a base station’s workload can be transferred to another idle base station. Base stations can be switched to sleep mode when data traffic is low. This can help to save a lot of electric energy. The final result will be a sustainable cellular base station. Most of the goals can be achieved by our proposed method like less energy consumption, carbon-free service, and less radio frequency (RF). This paper proposes a new solution like hybrid renewable energy along with sleep mode. Mobile operators can be benefitted from this paper to make their business sustainable and more cost-effective.
