Introduction:

As the implementation of UMTS gathers momentum worldwide, there’s increasing interest in the TDD mode of UMTS. This course addresses the need for a good, strong course on UMTS-TDD. In this course, you will build on your existing knowledge of UMTS-FDD networks by learning the structures added by TDD. The relationships between the logical channels, transport channels, and physical channels build on the corresponding relationships of the FDD mode, but they do bring in some added complexity, along with the added capabilities. We will discuss how to exploit these capabilities to come up with good network designs, trouble shoot performance problems, and identify solution approaches. This will help you do a better job of designing and optimizing UMTS-TDD networks as well interface more effectively with the equipment vendors.

Audience:

Those with some UMTS-FDD background who wish to learn more about UMTS-TDD. The standard presentation of this course assumes a bachelor of science in Electrical Engineering, Mathematics, Physics, or a related subject along with an appropriate background in communications engineering.

Prerequisites:

Knowledge of the wireless network structure and operation, RF propagation and fading issues, and link budget analysis. At least two years experience in the design and optimization of a wireless network using any major technology.

Customize it:

This 2-3-day UMTS course will be customized to your needs and specifications. Enowireless will assist you in identifying those needs and specifications. A word to the wise, there are many vendors of wireless training. They will typically have a broad and general course, one size fits all, already developed and just put your organization’s name on the title slide. This minimizes their effort and time investment. At Enowireless, every course is made to your exact and exacting specifications. We help you ensure what you are getting is what you really need even if at the beginning you weren’t too sure of what that was. We fit the class to your needs. We never fit you into our “standard”, one size fits all, class.
