[LTE_301] Mastering LTE Air Interface

Printer-friendly PDF version

Long Term Evolution (LTE) is a 4th generation (4G) wireless technology that delivers significantly higher data rates to users (up to 300 Mbps) while reducing the net cost-per-bit through a number of key enhancements, including OFDM, multiple antenna techniques, and all-IP networks. This course begins with a discussion of the LTE E-UTRAN architecture and the air interface protocols. It then provides an in-depth explanation of the LTE frame structure, channels, and multiple antenna techniques, and describes in detail how LTE devices synchronize with the network, establish connections and exchange data over the air. The impact of mobility on both idle and connected users is explained, showing how active sessions are maintained while the user moves through the network. The course wraps up with a brief summary of the enhancements offered by the next step in LTE technology, LTE-Advanced.

Learning Objectives

After completing this course, the student will be able to:
• Sketch the E-UTRAN network architecture and explain the roles of the important nodes and interfaces
• Describe the physical structure of the LTE air interface and explain the key underlying technologies
• Define the steps involved in setting up and managing a typical LTE data session in detail, including:
­ - System acquisition and access
­ - Registration and bearer establishment
­ - Uplink and downlink data transmissions
• Identify the mechanisms used to maximize performance and Quality of Service (QoS) over the air interface, including MIMO and CQI
• Explain how LTE tracks idle users and maintains active connections as the users move through the network

Intended Audience

This is a detailed technical course, primarily intended for a technical audience, including those in RF design, development, integration, deployment and systems engineering.
