This presentation shows the relative importance of microwave as an access technology. Packet microwave is the enabler to move backhaul networks, where microwave is dominant, from legacy connectivity to all packet. Packet microwave enables the presence of a end-to-end networking layer, be it L2, L3 or mixed, coupled with the microwave transmission layer, flexibly adapting to the topologies currently emerging in backhauling

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
