Ideal Platform for LTE Infrastructure

High Density • 2-10x advantage over legacy systems

High Speed • 10G and 40G bandwidth today, clear migration to 100G

High Performance, Heterogeneous Processing • Compute, Packet and Media processing • Switching & routing, Protocol engine, Deep Packet Inspection, Traffic shaping and

Management, Transcoding, …

Platform for Dataplane Transport *and* Services • Blurring the line for performance and ARPU enhancement • New network services - media-rich content processing and delivery

Flexible System Reconfiguration • Common platform for multiple elements • Evolution of requirements within a single element, shifting feature set and processing

needs

Commercial Considerations • Time to Market • Cost Competitiveness • Time in Market/Commercial Lifetime


ATCA LTE/EPC Value Proposition

Investment Protection & Scalability

Upgraded ePCs will need to get to market rapidly to deliver expected cost efficiencies

Increased sw content can help decrease TTM

Single Point Integration Centralized software

upgrades Centralized diagnostics Extensible framework for

TEMs to include their own customer sensors or watchdogs

System integration of Hub, Node and Chassis

Important with new high speed technologies

Redundancy is a pre-requisite for telecom environments
