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 thetransition 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
