All-in-Cloud Radio Solution

Growing importance of 5G Cloud RAN solution @ Edge

© 2019 Nokia9

4 Reasons to go for Cloud based 5G RAN

Network Optimization

• Cloud provides more flexibility for RAN w.r.t distributed vs centralized topology

• Cloud based dynamic network optimization and traffic steering

Edge Computing

• New business models with Public & Hybrid cloud, Neutral hosting

• E2E Slicing for diverse use case requirements e.g. for Enterprise market

Market Disruption

• Significant TCO reduction by Simplification, Automation and Operational efficiency gains

• Time to Market for new services

Open Ecosystems

• Early engagement with vendors and partner ecosystem for co-creation.

• Example: Co-create ORAN Architecture with RIC (RAN Intelligent Controller), Akraino and ONAP for 5G

TCO Analysis - Cloud RAN can provide 10-40% less TCO in a 5 Year Period

(Greenfield Scenario with NAM cost assumptions)

HW utilization

Pooled SW architecture delivers trunking gains, allowing compute resources dimension to average rather than peak traffic loads.

Serviceability

Cloud BTS 2021+ target to have 30-40% more efficient services compared to classical BTS deployments with automation

Transport

Multiplexing brings significant transport saving (Assumed multiplexing gain of ~3x) for cloud solution while comparing centralized scenarios

Key assumptions• Over-deployment, Multi-tenancy,

server sharing considered• Configuration: 9000 cells

• 750 Radio Sites (12 cells/site) • 30 CRAN Sites (300 cells/site)

• Fiber cost 1200€/fiber/year• Static deployment, no upgrades

considered

Cloud is more than centralization; enabling multi-tenant Cloud infrastructure to host variety of applications
