Five Disruptive Technology Directions for 5G

Understand

New research directions will lead to fundamental changes in the design of future 5th generation (5G) cellular networks.

• This paper describes five technologies that could lead to both architectural and component disruptive design changes: device-centric architectures, millimeter Wave, Massive-MIMO, smarter devices, and native support to machine-2-machine.
• The key ideas for each technology are described, along with their potential impact on 5G and the research challenges that remain.
