Course in a Nutshell
Good traffic engineering is not only an essential element of a network’s initial design but also critical to its smooth, ongoing operation. The job of the engineer responsible for traffic on a mobile network has recently become more important as well as more complex. Traffic is growing faster on mobile networks than on traditional, land line, fixed infrastructure networks. This growth in mobility traffic is paralleled by the increasing growth and diversity of mobility based data applications and services along with a continuously changing subscribers’ services profile. And, of course, any analysis of traffic over radio channels must also account for the radio related impacts to capacity which can be dynamic in nature.
In this course, you will study traffic engineering from multiple angles including an overview of the various RF modulation techniques popular in commercial networks today, and how those modulation techniques impact available capacity. Emphasis is placed on understanding the correct methodology to use for a particular service and achieving the highest level of utilization and efficiency without sacrificing the quality of service. The course will not only arm you with a good understanding of when to employ the appropriate Erlang or other traffic model, it will also give you a new level of sophistication in ensuring the quality of service (QoS) for your subscribers while maximizing the utility of your network.
Customize It!
For little to no added cost, we can tailor this course to the topics and challenges that are pertinent to your job. For instance:
- If you are a network engineer with a mobile or fixed wireless operator, we can focus on the areas of interest to you, whether planning, growth, capital budgeting, operations, or other.
- If you are you an RF engineer who would like to “fill in the holes” in your knowledge of networks, we can present an overview of the state-of-the-art of mobility networks and how traffic engineering plays a key role in the evolution towards policy based networks.
- If you are in marketing and interested in value-added services, we can highlight the types of new services that are enabled by 2.5G and 3G/3G+ and how capacity and quality-of-service (QoS) tradeoffs become key in developing a marketing and applications strategy.
- If you are a manager or executive concerned with technology and migration strategy, we can emphasize the economic impact of the evolving technologies as related to traffic and capacity management.
Learn How To
- Effectively apply Erlang B, Extended Erlang B, and Erlang C to the solution of mobile traffic engineering problems.
- List the key differences and impacts to capacity of fractional frequency reuse systems versus CDMA or WCDMA systems and how those differences affect traffic engineering.
- Describe the major components of the mobile network architecture, including signaling, and how they work together.
- Describe how different services place different impacts on the network and utilization of resources.
Aimed At
