Estudo sobre a eficiência energética em redes 5G.

Abstract

The fifth generation (5G) of cellular mobile communication systems is currently in the final stages towards standardization. Once it is approved by ITU-R, 5G will be designated as IMT-2020 (International Mobile Telecommunications - 2020). Presently much is already known about how will 5G be, including the fact that 5G will represent not just another evolutive step as compared to the previous generations of mobile systems. What is required for 5G is the realization of a technological breakthrough much bigger than those achieved between previous generations of mobile systems. Several performance targets have been imposed on 5G. One of them: the energy efficiency for 5G must be 100 times that achieved by 4G systems. This work has investigated some aspects concerning how this target can be realized. An effort has been spent in order to quantify energy efficiency for 5G systems. It has become clear the important role of the RF PAs (power amplifiers) used in the radio base stations on the global energy efficiency of a 5G network.
