Energy Efficient Green Mobile Communications in India by 2020

Energy efficiency is an important issue in the proposed next generation wireless communications by 2020 as it severely effects the human life on the earth surface mainly on two factors has become energy concern during the past decade. The two factors of concern are global warming due to CO2 emission and sea level raise. Further, this issue has become more concern due to the ever increasing demand of data rates, spectral efficiency and quality of service combining with massive IoT communications. Therefore there is need to develop a green mobile communications by 2020, which can give reduced energy consumption and increased battery life besides increased capacity to enable massive deployment of small cell base stations. The proposed wireless communication network with the above features is referred to an energy efficient green mobile communication (5G). In this paper a survey of various technologies that are proposed for realization of the green mobile communication have been discussed in brief. Various technologies proposed for the realization of 5G are simultaneous wireless power and information transfer, massive multiple input multiple output, millimeter waves and beamforming. Analysis has also been carried out in case of the proposed massive MIMO antennas and beamforming technique as a case study of energy efficient architecture.
