Course Overview:

LTE RF Network Design Training Course Description

This LTE RF Network Design Training workshop seeks to equip you with an in-depth understanding of the technical aspects of LTE/SAE necessary for the design, analysis and deployment of this exciting new radio technology.

The initial portion of this LTE RF Network Design Training course presents an overview of basic core network and air interface standards including system components, reference points, protocol stacks and fundamental concepts that form the basis for the rest of the course. Each module of this LTE RF Network Design Training course builds upon the previous modules, culminating in the use of a propagation modeling tool to estimate the performance of an LTE network, based on equipment specifications, system configuration and environmental variables. This how-to course, emphasizing calculator exercises and detailed analysis using the spreadsheets included in the LTE RF Network Design Training course, will help you learn practical techniques that you can put to immediate use on your job.

Customize It:

• If you are familiar with some aspects of this LTE RF Network Design 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.
