Proprietary and Confidential

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

21

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
