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

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
