The road to 5G wireless backhaul
Proprietary and Confidential
"We’re running out of spectrum – it’s too congested"
"We need to better control installation and provisioning costs"
"We need a partner who can build AND optimize our network“
"Our power-related expenses are too high"
"Any service interruption is damaging to the business"
"We need to handle capacity surge to the last mile (1-2Gbps)"

• Differentiation between different traffic classes (CoS)
• Services within the same traffic class are treated as a single aggregate with no isolation
• Limited per-service visibility and control
• Each service gets its own personalized treatment
