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

7

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

9

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


10

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
