WiMAX Traffic & Capacity Engineering

Introduction:

WiMAX Traffic and Capacity Engineering Training Course in a Nutshell

3G and 4G mobile networks are rapidly evolving to a mixed usage model where data will become increasingly more prevalent in the mix of traffic demanded by consumers. The increasingly diverse voice/data mix includes services such as VoIP, web-browsing, presence, online gaming, streaming, and IPTV. Wireless carriers must develop a good understanding of the user data patterns and apply sophisticated traffic/capacity and Quality of Service (QoS) management techniques to be able to offer a network that responds effectively to their subscriber needs.

Understanding of the varied traffic mixes, prediction of capacity requirements, impact to network policies, spectrum utilization and performance, buffers, quality of service and impacts of and to mobility management are some of the key factors in unlocking the potential of a WiMAX enabled network. In this WiMAX Traffic and Capacity Engineering Training course, we will undertake an in-depth study of these and related WiMAX packet traffic engineering issues.

Customize It:

● If you are familiar with some aspects of this course, we can omit or shorten their discussion.
● We can adjust the emphasis placed on the various topics or build the course around the mix of technologies of interest to you (including technologies other than those included in this outline).
● If your background is nontechnical, we can exclude the more technical topics, include the topics that may be of special interest to you (e.g., as a manager or policy-maker), and present the course in manner understandable to lay audiences.
