While the 5G technology of cellular communications promises great capacity and coverage to access information anywhere and anytime, it is feared to have huge power consumption. Significant research been has been directed towards solving this problem which exists both on the subscribers side as well as the operators side. There have been efforts like predicting traffic, modifying the physical layer etc. towards making the 5G technology more energy efficient. The aim of this study is to see the technology enablers for 5G from an energy efficiency perspective. Efforts will be made to point out specific areas in 5G cellular where improvements or modifications could make 5G cellular more energy efficient.
