Wireless Broadband Training - Course 1:

Exploring IP / Ethernet Backhaul

Instructor Led | Duration: 2 Days


The 4th generation (4G) of wireless technologies promises a much higher air interface data rate (over 100 Mbps) to users while reducing the cost per bit for wireless service providers. The current T1/E1 backhaul will not be able to support the high data rate with reasonable costs. The backhaul is already becoming the bottleneck in the existing 3G networks and will continue to be a challenge for emerging 4G networks. These networks require IP based broadband backhaul solutions. This course provides the background and solutions for IP backhaul planning for 3G/4G radio networks, starting with a review of the trends in 3G/4G wireless data services and related backhaul challenges. An overview of IP/MPLS is given since it is seen as an emerging technology for backhaul operation. Finally, deployment considerations and a backhaul migration path are discussed along with an exercise to calculate the backhaul requirements.

Course 1 Outline: Exploring IP / Ethernet Backhaul

Intended Audience
This course is designed for those involved in planning, design and engineering of 3G/4G backhaul systems. It is suitable for backhaul network engineers and managers involved in deployment and operation of 3G/4G networks.

Learning Objectives
After completing this course, the student will be able to:

  • List the requirements for 3G/4G backhaul
  • Describe the challenges for 3G/4G backhaul
  • List wireless network backhaul options
  • Discuss the role of IP in cellular networks
  • Explain ATM/TDM benefits, operations and QoS support
  • Explain IP/MPLS benefits, operations and QoS support
  • Explain Carrier/Metro Ethernet benefits, operations and QoS support
  • Describe benefits, challenges and applications of wireless backhaul
    solutions such as microwave and WiMAX
  • Compare different backhaul facilities and explain the pros and cons of the available solutions
  • Apply the QoS concepts in IP backhaul
  • Sketch the 3G/4G IP backhaul deployment architecture
  • Apply traffic models to forecast backhaul requirements and calculate link bandwidths
  • Calculate protocol overhead for various backhaul options for voice,
    Web, video etc.
