- Aimed At
-
This course is aimed at a technical audience and is suitable for personnel at all levels from technician through manager who are involved in implementing LTE/SAE or who wish to keep up with future generation network technologies.
- Prerequisites
-
Those wishing to take this course should have a basic knowledge of UMTS and HSPA.
- Course in a Nutshell
-
LTE is a fourth generation mobile communication technology standardized by the 3GPP which enables support for broadband connectivity to mobile devices, permitting the delivery of demanding multimedia information to any device, anywhere, anytime. In support of this, changes to the core network are also defined as System Architecture Evolution (SAE), providing an all-IP bearer platform for delivery of services.
This course will provide you with a comprehensive understanding of the development, design, and capabilities of LTE/SAE. The course will begin with a review of existing 3GPP and alternative technologies. The LTE access and core network elements are described in detail, and methods for implementing the logical interfaces are discussed. The air interface is examined from a technology viewpoint as well as a procedural viewpoint. The course finishes with a study of signaling, interworking with non-3GPP networks and the security capabilities of LTE/SAE.
- Customize It!
-
This course is designed to put LTE/SAE into perspective and includes a review of both its radio access and core network aspects. However, if we can customize it to emphasize certain topics of interest to you or to include additional topics from the Related Courses (see that section), please let us know. All reasonable customization is included at no added cost.
