Course Overview:

LTE Functionality Training – In-depth

This LTE Functionality Training course will undertake an in-depth study of the LTE air interface.  The LTE Functionality Training 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. We  conclude with a discussion of the LTE idle mode functionality and physical layer procedures with emphasis on the channel quality and random access techniques. Also connected mode — with emphasis on scheduler, power control and Link Adaptation — is further analyzed, and user mobility cases are explicitly presented with emphasis on parameter configuration and optimization.

Customize It:

• If you are familiar with some aspects of this LTE Functionality Training course, we can omit or shorten their discussion.
• We can adjust the emphasis placed on the various topics or build the course around the mix of technologies of interest to you (including technologies other than those included in this outline).
• If your background is nontechnical, we can exclude the more technical topics, include the topics that may be of special interest to you (e.g., as a manager or policy-maker), and present the course in manner understandable to lay audiences.

Audience / Target Group:

The target audience for this LTE Functionality Training course:

● Technical personnel with a good understanding of UMTS/WCDMA and some prior LTE background who wish to study LTE operations in depth.
