Operator Views on NFV
C-RAN Market to grow to $11.31B in 2018 at a CAGR of
45.9%
Operators Looking forward to NFV Based Transformation
Source: Infonetics Research
By 2018, 62% of LTE operators will support the
NFV
Scale Services
Use SW for quick revenue
Use commercial servers
Operational Efficiencies
Multi Tenancy
Real Time network Optimization
Save Energy by consolidating
workload
VNFs from small players

RAN Evolution: Why?
HetNet Deployments are picking up but not without challenges
Cost and complexity of network planning
When it comes to capacity management, redirection alone is not sufficient
C-RAN promises improved network efficiency, with lowered TCO, to improve monetization of mobile broadband

Cloud RAN
Centralizes components of the RAN
Using generic hardware to host RAN functionalities
Simple software upgrade for new technologies
Efficient connection management and failover mechanism
Simplifying the network synchronization needs for features like CA and CoMP
Centralized SON leads to automated network planning/reorganization

Cloud RAN EvolutionIndustry participation
China Mobile and Alcatel-Lucent demonstrated an LTE RAN Baseband Unit (BBU) based on NFV principles at Mobile World Congress 2014
China Mobile publishes Whitepaper describing key benefits of C-RAN in 2013
ETSI is working to standardize NFV concepts. C-RAN proof-of-concept results and findings is expected during the summer of 2014
Small Cell Forum presents new virtualized/Cloud-ready Small Cell Architecture
