Agenda
• Understanding capacity requirements and expected traffic patterns in
the Asian market
• Redefining Asian mobile operator's expectations from the backhaul
segment of their networks
• Making Mobile Broadband accessible in Asia with backhaul solutions
that meet mobile broadband growth, capacity and coverage
requirements
• Discovering how to deliver more capacity gain in an HSPA+/LTE
environment

3 simple steps for successful wireless transport design
Making 3G/4G Broadband Profitable
1. Squeeze maximum capacity from available spectrum
2. Focus on Quality of Experience
3. Choose a modular risk-free approach
- Maximize return on investment
- Differentiated services for differentiated revenues
- Keep revenue generating services

3G backhaul capacity upgrade
Capacity Requirements• 7 ring sites:
• 3xE1 for 3G (Ethernet)
• 2xE1 for 2G
• 7 spur sites:
• 3xE1 for 3G (Ethernet)
• 1xE1 for 2G
• Overall ring supports:
• 21xE1
• Ethernet capacity of 84MBps.
• Site F is the aggregation site

F
• 3G is all packet, launched in 2010
• 2G is the bread and butter, all TDM
• Backhaul is based mainly on microwave radio
• Limited and expensive backhaul spectrum
Upgrade capacity in an impossible environment

Implementing more capacity
Increase capacity by applying all 3 techniques
1. ABR: Adaptive Bandwidth Recovery
2. Asymmetrical: Bandwidth planning and delivery
3. Compression: Multi layer header compression
