- 5-10 day(s)
- Aimed At
-
This course is aimed at the special needs of those involved in the development of hardware or software for LTE systems. It will also be of interest to radio planners and other interested in a detailed treatment of the LTE air interface.
- Prerequisites
-
The participants should have an understanding of the LTE principles and familiarity with HSPA MAC layer scheduling issues.
- Course in a Nutshell
-
This course, suitable for software and hardware designers, radio planners, and others interested in the subject matter, presents an in-depth discussion of the principles of operation of the LTE technology including the LTE air interface and LTE functionality. Here you will learn about OFDM, MIMO, air interface functionality, and RRM/mobility principles in order to acquire a solid understanding of the LTE e-UTRAN functionality. The course will focus in great detail on the Scheduler, the heart of the LTE e-UTRAN operation. Having mastered the Scheduler functionality, you will have a better appreciation of the strengths and weaknesses of the LTE functionality as well as how to fine tune the Scheduler to achieve the highest possible bit rates.
- Customize It!
-
We can customize this course to your specific project requirements. If you would like to take this course but lack the requisite understanding of HSPA and LTE principles, we can augment the course with an up-front overview of the prerequisite material. Depending on the level of detail desired, the course can be completed in 5-10 days. Many clients begin with a 5-day “overview” version of the course to bring everyone up-to the same level of understanding. This is followed by a 5-day sequel covering in greater detail the select topics of particular relevance to their current requirements.
