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

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 Evolution
Industry 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
