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
