The 4th generation (4G) of wireless technologies promises a much higher air interface data rate (over 100 Mbps) to users. Delivering such high data rates requires a very fast and efficient backhaul network. The current T1/E1 backhaul cannot support such high data rate with reasonable costs. These broadband networks require all-IP and Ethernet based broadband backhaul solutions. The first two days of this course explore various technology options and architectures for Ethernet backhaul solutions, including MPLS, Metro Ethernet over fiber, copper and microwave radio deployments. The third day introduces various planning tools needed for multimedia network planning. This requires a management network capably of viewing the applications network as a system rather that a series of network elements. The course focuses on demonstrating methods for estimating the backhaul requirements based on the type of geography served, expected adoption of new networks and traffic models for key applications. This is demonstrated through a detailed capacity planning exercise using Excel spreadsheets provided to the participants. Required equipment: PC laptop supporting Microsoft Excel
Learning Objectives
After completing this course, the student will be able to: • List the requirements and challenges for 3G/4G backhaul and wireless network backhaul options along with comparing different backhaul facilities and explain the pros and cons of the available solutions • Discuss the role of these key technologies from a backhaul perspective, their operations and support: ATM, TDM, MPLS, Carrier Ethernet and IP • Sketch the 2G/3G/4G integrated IP/Ethernet backhaul deployment architecture with full redundancy • Compare key traditional and packet based timing and synchronization methods such as IEEE 1588 • Apply the end-to-end QoS concepts in IP and Ethernet integrated backhaul and their usage in SLA monitoring • Calculate protocol overhead for various backhaul options for voice, Web, video, etc. and overhead required for various backhaul options • Explain backhaul/Ethernet testing scenarios with RFC 2544 and Y.1731 in-network testing and illustrate methods of configuration and fault management using CFM, E-LMI and EFM • Demonstrate how reliability analysis is used to achieve network availability requirements (Download PDF for full list of learning objectives)
