- duration
- 3 day(s)
- Aimed At
-
This course is aimed at technical professionals who are familiar with 2G, 3G, and/or other 4G (such as WiMAX) wireless technologies and desire a comprehensive overview of the LTE technology.
- Prerequisites
-
Familiarity with 2G/3G technologies or WiMAX.
- Course in a Nutshell
-
The course begins with a review of the digital modulation techniques, radio propagation characteristics, and the 3GPP WCDMA system. This is followed by a discussion of the principles of OFDM, multipath mitigation techniques, and the LTE system components. The course concludes with a comprehensive look at the various LTE system operation scenarios and a study of link budget and system capacity examples.
