Abstract

Energy efficiency is an important issue in the proposed next-generation wireless communications as it severely affects human life on the earth. Two factors have mainly become an energy concern in the past decade: global warming due to CO2 emission and sea-level rise. Further, this issue has become a graver concern due to the ever increasing demand for data rates, spectral efficiency and quality of service combined with massive IoT communications. Therefore, there is a need for developing green mobile communications by 2020, which can ensure 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 as an energy-efficient green mobile communication (5G). The paper surveys various technologies for realization of green mobile communication. Various technologies proposed for the realization of 5G are simultaneous wireless power and information transfer, massive Multiple Input Multiple Output (MIMO), millimeter waves and beamforming. An analysis has also been carried out in the case of the proposed massive MIMO antennas and beamforming technique as a case study of energy-efficient architecture.


Description

Information and communication technology has experienced tremendous success in providing broadband wireless services. Till now, revolution in the wireless technologies focused on improving the network coverage and capacity, with good quality of service provided to the users. Today, mobile subscribers are almost more than half of the world population. Due to this, the energy consumption is increasing day by day, which will cause an increase in the carbon dioxide (CO2) emissions globally, and enforce more and more challenging tasks for network designers and operators. Energy Efficiency (EE) is one of the concerns in the wireless communication growth paradigm. This is the main motivation for investigating the techniques which will remarkably improve the EE of wireless communication systems, thereby minimizing the operational cost and environmental impact of broadband mobile services. Surveys indicate that the mobile information and communication technology would produce more than 350 million tons of greenhouse gases per year by 2020 (Etoh et al., 2008). The paper addresses energy issues in the present cellular communication and provides a survey of various technologies which will be adopted in the 5G networks to improve the EE; also, analysis has been carried out in the case of the proposed massive Multiple Input Multiple Output (MIMO) antennas and beamforming technique.
