- duration
- 4-5 day(s)
- Aimed At
-
Technical personnel who have a good understanding of UMTS/WCDMA and some prior exposure to LTE and who wish to study the LTE air interface in depth.
- Prerequisites
-
- LTE/SAE: A Technology Overview (3 day(s), LTE-TECH)
- UMTS-FDD: Network Architecture, Operation, and Design (3 day(s), UMTS-FDD)
The UMTS course, or equivalent knowledge/experience, is a required prerequisite for this course. LTE overview is a recommended prerequisite but not required.
- Course in a Nutshell
-
This course will undertake an in-depth study of the LTE air interface. The course will begin with a discussion of the radio channel environment and the related RF propagation issues to help you understand the problems that OFDM/MIMO solve. This is followed by a discussion of the modulation principles along with a detailed look at the LTE physical layer structure as it complements the modulation and MIMO channels. The transmitter and receiver parameters and techniques, based on the 3GPP specifications, are then presented. The course concludes with a discussion of the LTE idle mode functionality and physical layer procedures with emphasis on the channel quality and random access techniques.
- Customize It!
-
- If some of your participants lack the necessary WCDMA/LTE background, we can teach an extended five-day course that includes WCDMA principles, LTE overview, and LTE air interface techniques.
- Add a workshop day at the end of the course, for a total of five days, for a deeper dive into capacity planning and coverage calculations
