| Course Abstract: |
This course introduces participants to the next generation of mobile broadband technology, Long Term Evolution (LTE). LTE represents an evolution from existing 3rd generation (3G) technologies to 4th generation (4G) mobile broadband technologies. LTE delivers increased peak data rates, improved spectrum efficiencies, reduction of air interface latency as well as other benefits. LTE provides a platform for bandwidth intensive mobile broadband applications such as video conferencing, mobile, online gaming and many other social and business applications. LTE is also optimized for IP traffic, allowing for additional benefits in terms of speed, integration and scalability.
The course examines the market forces behind the creation of LTE, LTE’s core components and architecture, air interface, protocol stacks and control and user planes. The course traces a data call from an LTE enabled device or user equipment (UE) through the architecture out to the Internet and back to the UE. The course details the workings of the UE from powerup to network acquisition as well as tracking and handover procedures for the mobile UE. Quality of Service (QoS), a key feature of LTE is discussed in all its aspects, from the radio network, through to the core network. The course also overviews key technologies and concepts associated with LTE including the IP Multimedia System (IMS) Multi Protocol Label Switching (MPLS), IPv6 and advanced antenna technologies such as MIMO. The course concludes with a discussion of how LTE integrates with existing 2G and 3G networks and architectures.
