Course Overview

Course in a Nutshell

LTE is a 4G wireless 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 studied in detail, and methods for implementing the logical interfaces are discussed as well. The air interface is examined from a technology viewpoint as well as a procedural perspective. 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.

  • "Liked the step-by-step approach starting with an overview on day one, the instructor’s humor, and the summary and notes contained in the course book. I’d recommend it to anyone, interested in getting an understanding of the full scope of LTE, such as a carrier would need to know." – JD, Director, Technology Services, Leading US Wireless Equipment Manufacturer
  • “Very solid, simple to understand with rich graphical examples. Instructor – as in all courses – very knowledgeable about the course topics.” - Benjamin Magana Salazar, RF-OPS Coordinator, Nextel
