5. EVOLUTION OF BACKHAUL
CHANGE 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
- 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
