- 5 day(s)
- Aimed At
-
This course is aimed at technical audiences who have prior understanding of WCDMA and some exposure to LTE who need a workshop-style course on the LTE radio network design issues.
- Prerequisites
-
- LTE/SAE: A Technology Overview (3 day(s), LTE-TECH)
- UMTS-FDD: Network Architecture, Operation, and Design (3 day(s), UMTS-FDD)
The LTE overview course is strongly recommended, though not required.
- Course in a Nutshell
-
This 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 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 rest of the course. Each module of this 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 course, will help you learn practical techniques that you can put to immediate use on your job.
- Customize It!
-
If you would like to take this course but don’t have the requisite understanding of WCDMA/LTE, we can extend the course to include an up-front overview of WCDMA/LTE. The course may also be customized to your project requirements or operational environment.
