The fifth-generation (5G) of mobile communications networks is emerging as a revolutionary technology that will accelerate the development of smart cities and the realization of the information society. This paper aims to provide an introduction to 5G for non-specialists, and a survey of this new technology for those already familiar with mobile communications, covering the conceptualization and the core technologies underpinning 5G networks. The paper also discusses the status of the commercial roll-out of 5G until 2020 from a worldwide perspective and gives a future view of mobile communications beyond 5G.
