- Aimed At
-
This course is aimed at a technical audience and is suitable for personnel at all levels from technicians through managers who are or will be involved in deploying LTE or who wish to keep up with future generation network technologies.
- Prerequisites
-
Those wishing to take this course should have a basic knowledge of the radio access aspects 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. The radio access network and especially the air interface is the major focus of technology enhancements which enable the high bit rate broadband data transfers between the service platform and the mobile devices.
This course will provide you with a comprehensive understanding of the development, design, and capabilities of the LTE radio technologies and access network. The course will begin with a review of existing 3GPP and alternative technologies. The LTE access network is described in detail, and a brief description of the core network is provided. The LTE air interface is examined in detail from a technology viewpoint as well as a procedural viewpoint. The course finishes with a study of LTE operations and procedures and a look forward into the future to see what LTE Advanced promises.
- Customize It!
-
Let us know your reason for studying LTE so we can customize the course to your specific needs. The course is designed to focus on LTE radio aspects, but a brief study of core network elements is included so the audience will see how the radio access interacts with the core network. A longer course, combining both the radio and core network topics is also available.
