C-RAN: Virtualizing the Radio for SDN/NFV

Purchase

C-RAN is new radio access network architecture that had been proposed by China Mobile Research Institute and Intel in 2010 to solve some of the problems related to traditional structure and allows better deployment for next generation mobile networks.

The first section of this report explains the concept of C-RAN by drawing a wider picture of the current challenges of the traditional RAN architecture and the motivations to adopt a new one. System architecture and components are then clarified. Finally, C-RAN enablers and expected advantages are listed.

The second section deals with the current market and ecosystem including major operators who currently deploying or trialing, vendors’ profiles, joint research, and industry collaborations.
