Emerging 3G and 4G networks reflect two key fundamental changes in wireless networks. The first change is the trend toward an “all IP” network and the second change is a more efficient radio interface resulting in a huge growth in the volume of traffic supported by the air interface. Traditional backhaul using T1/E1 leased lines is no longer economical so new backhaul solutions are being deployed. This course describes the key issues leading to the need for new backhaul solutions and provides an overview of the various backhaul solutions and related technologies. It introduces the backhaul network architecture and reviews technologies such as ATM, DSL, Bonded T1/E1, DOCSIS, Microwave Radio, PON, Carrier Ethernet, MPLS/MPLS-TP and PBB-TE. A backhaul capacity planning and technology migration scenario is presented, and the course ends with an exercise to test the student’s comprehension of the topics covered.

This course is suitable for those looking for a high level conceptual overview of IP/Ethernet backhaul networks and an introduction to associated technologies.

After completing this course, the student will be able to:
• List the requirements for 3G/4G backhaul
• Describe the challenges for 3G/4G backhaul
• Differentiate between the access and aggregation networks
• Identify the networking options most likely deployed for Ethernet Backhaul (EBH)
• Discuss the role of various technologies in backhaul networks
• Explain benefits of Carrier Ethernet and list various services provided for backhaul
• List the key issues related to migrating to an Ethernet-based backhaul network
• Identify tools and techniques used to seamlessly migrate to EBH
• Compare different backhaul facilities and explain the pros and cons of the available solutions
• Explain where faults in the EBH network may occur, and how these faults are detected and isolated
• Identify the key challenges in sizing backhaul capacity links
• Sketch possible migration path from a T1/E1 based backhaul solution to tomorrow’s IP/Carrier Ethernet based backhaul solution
