Course Overview

Course in a Nutshell

3GPP LTE is one of the two broadband mobile wireless technologies meeting all of the ITU IMT-Advanced 4G requirements. It provides a high-capacity, flat IP, mobile data network based on OFDMA/MIMO with low latency that is suitable for many forms of multimedia delivery. It has a flatter architecture, offering the network operators lower cost per byte. LTE interfaces with IMS to provide architecture, framework, and QoS mechanisms for applications/services including voice and video (conversational, streaming, and conferencing), gaming, and instant messaging. Consequently, LTE is becoming the de-facto worldwide standard for mobile broadband.

Since LTE provides a flexible platform for all types of 4G communications, it behooves us to examine its suitability for public safety applications. Public safety organizations require data communications paths that are reliable at all times, so that in the event of an emergency, e.g., a natural disaster or act of terrorism, all real-time and mission-critical data transmission in and out of the incident zone can be guaranteed timely reception, without suffering network congestion. As we will learn in this course, LTE can be deployed to meet these critical requirements, either using a public commercial network or a private network designed specifically to provide the types of services needed by public safety organizations.


Customize It!

We can customize this course to add or delete topics or adjust its “tech level” up or down to meet the needs of your group.


Audience / Prerequisites

Aimed At

This course is aimed at federal, state, and local public safety and law enforcement organizations, and companies who work with them, who wish to better understand how LTE may be leveraged for public safety communications.



Those wishing to take this course should have a working knowledge of wireless technologies through UMTS/HSPA either through job experience or prior training.
