4. Summary

EVOLUTION OF BACKHAULCHANGE IS INEVITABLE

• Traffic mix is changing

- Voice is becoming a minor part of total traffic- Video and content consumption is booming

• Traditional backhaul is not sustainable

- Legacy TDM and ATM no longer meet backhaul requirements and must co-exist with new solutions


5

with new solutions- Wireless traffic growth forecast to double

every year through 2015; legacy equipment cannot scale

• Ethernet and IP dominate

- Evolution to IP/Ethernet to support LTE- Microwave backhaul has moved to packet- Introduction of heterogeneous networks

OVERCOMING THE BARRIERS

Any G support?

Getting to the cell site?

Network scalability, flexibility, reliability?

Operational impact?

WHAT IS PACKET MICROWAVE?

One Product Family – All Microwave ApplicationsMinimize sparing & operations costs by using common radios across tail, point-to-point, nodal, full-outdoor and long-haul applications

Native Packet Networking SupportEnable legacy to packet transformation while capitalizing on the benefits of native packet transport

High-Capacity and High-Availability


10

Flexible NetworkingFacilitate transition to higher-capacity, lower TCO MW network architectures using Ethernet, MPLS-TP, or IP/MPLS

High-Capacity and High-AvailabilityAddress growing bandwidth demand while improving customerQuality of Experience

End-to-end Service-Aware ManagementLower OPEX through simplified provisioning, assurance and maintenance
