Long Term Evolution (LTE) is a radio technology 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 order to make use of such high speed data in public safety services, 3GPP initiated in release 12 to enhance LTE standard to meet public safety feature requirements and included Group Communication System Enablers (GCSE) and Proximity Services (ProSe). This course provides a high-level overview of LTE network architecture, air interface and procedures, and steps through the architectural enhancement for Group Communication System Enablers (GCSE), which is a key requirement for Public Safety Agencies, PS implementation models, dedicated bearer set up process and typical call flow scenarios.

This course provides a high level over view of LTE networks and a comprehensive overview of its enhancements to support public safety features. It is suitable for telecom professionals, operators and Public Safety engineers who want to understand how PS can be implemented through an LTE network

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 key concepts in the LTE air interface
• Explain network acquisition and EPS bearer setup
• Describe Group Communication System Enablers and Proximity Services supported in LTE networks
