[LTE_209] LTE Technology Overview with Public Safety Features

Printer-friendly PDF version

Long Term Evolution (LTE) is based on OFDM and MIMO technologies and provides much higher data rates (over 100 Mbps) to users while reducing the cost-per-bit for service providers. This is very exciting to wireless operators who are eager to deploy multimedia rich Internet content over a wireless medium with seamless access anywhere at any time. In Release 12, 3GPP initiated special features to enable Public Safety operators/users to LTE networks and included special features like Group Communication System Enablers (GCSE) and Proximity Services (ProSe). This course describes the simplified architecture of LTE, enhancements to support public safety features, and moves on to the air interface, frames and channels on the air interface, and resource management and scheduling considerations at the MAC layer.

Learning Objectives

After completing this course, the student will be able to:
• List the requirements and capabilities of LTE
• List the requirements of public safety features in LTE
• Explain the network architecture of E-UTRAN and EPC
• Sketch the LTE architecture enhancements to support public safety features
• Describe the use of OFDM and multiple antenna techniques in LTE
• Describe the frame structure and channels in the LTE air interface
• List steps for network acquisition (Initial Attach) and EPS bearer setup
• Describe the traffic operation in DL and UL
• Describe Group Communications in LTE networks
• Describe Proximity Services in LTE networks
• Describe implementation models for Public Safety
• Describe the concept of MCPTT and IOPS in LTE networks
