Can Green Telecommunication Base Stations Be Connected to the Internet and Are They Safe

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.

Why should telcos use green networks?

The main aim of green networks is to minimise energy consumption while maximising efficiency and optimisation. While the introduction of green networks certainly has an ethical imperative, energy costs currently account for approximately 20-40% telco opex.

What should a base station do in a wireless communications network?

In a wireless communications network, the base station should maintain high-quality coverage. It should also have the potential for upgrade or evolution. As network traffic increases, power consumption increases proportionally to the number of base stations. However, reducing the number of base stations may degrade network quality.

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.

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.

Why do we need green mobile networks?

Curtailing these costs through the deployment of green mobile networks is as much of an ethnical imperative as a business one. Green networks are also those which minimse the embodied carbon involved in the manufacture, supply and construction of the networks themselves.
