- Aimed At
-
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
-
- CDMA Technology and Its Evolution to cdma2000 (3 day(s), CDMA)
- UMTS-FDD: Network Architecture, Operation, and Design (3 day(s), UMTS-FDD)
- 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.
- Course in a Nutshell
-
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.
