Five disruptive technology directions for 5G

Abstract

New research directions will lead to fundamental changes in the design of future 5th generation (5G)/ncellular networks. This paper describes five technologies that could lead to both architectural and/ncomponent disruptive design changes: device-centric architectures, millimeter Wave, Massive-MIMO,/nsmarter devices, and native support to machine-2-machine. The key ideas for each technology are described,/nalong with their potential impact on 5G and the research challenges that remain.
