Senza Fili new report “Charting the path to RAN virtualization: C-RAN, fronthaul and HetNets” discusses the market trends, operator requirements, and technology opportunities driving the transition to a virtualized RAN, through the deployment of C-RAN and fronthaul, and running in parallel to the densification enabled by small cells, DAS and, more generally, HetNets. 

Report topics:
- Where does RAN virtualization fit in?
- The emergence of a new RAN topology.  From distributed RAN to C-RAN and virtualized RAN
- From local to advanced C-RAN.  Multiple types of C-RAN to target different environments 
- Picking the right C-RAN architecture.  Assessment of multiple tradeoffs crucial to successful C-RAN deployments 
- The path to virtualization.  The role of the RAN within the NFV platform  
- Fronthaul, the great enabler of C-RAN and vRAN architectures.  A bottleneck or a requirement to meet?
- Fronthaul beyond CPRI.  CPRI alternatives attract operators’ attention
- Tradeoffs can ease the way to RAN virtualization.  Functional split options to facilitate or enable the transition to C-RAN 
- Drivers to a virtualized RAN: cost.  Cost dynamics in the short term and in the long term 
- Drivers to a virtualized RAN: mobility and interference management.  Toward a more efficient use of network resources in      densified networks 
- Drivers to a virtualized RAN: statistical multiplexing.  Leveraging uneven traffic distribution to optimize resource utilization 
- Implications: The death of the cell?  Moving baseband processing to the cloud erases RAN boundaries

This report also includes in depth interviews with Airvana, ASOCS, Fujitsu, Radisys, SOLiD, Oi, Orange, Softbank and Telefonica
