This course provides specialized information related to long term evolution (LTE) radio access network (RAN) optimization from a non-vendor perspective, providing an overview of all the aspects of the radio access network for LTE with respect to performance and optimization.
Conventionally a wireless technology course details and lists the important problems a technology solves, describes solution architecture, how it operates and specific use cases. However, this course is different than a standard technology course. This course focuses on the optimization techniques and areas to target when it comes to 4G LTE Optimization and Performance.
4G LTE is a purely packet switched network technology and it comes with its own set of optimizing challenges such coverage, interference, mobility, capacity and quality. In this course we will address how the above-mentioned performance challenges can be solved in 4G LTE Optimization.
LTE Optimization mainly refers to the pre-optimization and the continuous optimization before and after the network is launched. This course covers RAN aspects of 4G LTE Optimization starting with the six different types of key performance indicators (KPIs) defined in third generation partnership project (3GPP) standard, including topics such as how each one of these KPIs are computed, what parameters and configuration affect these KPIs, and how these KPIs can be optimized. This course also covers the practical aspects of these KPIs and how it will affect the end consumer experience.
Optimization in 4G LTE is different than 2G and 3G technology, therefore conventional optimization techniques are not applicable for 4G LTE, hence a dedicated course for LTE Optimization is more helpful to answer your 4G LTE specific questions.
Course participants will be provided with starting points to consider and to investigate whenever they are faced with a throughput optimization problem in LTE. The instructor provides practical industry wisdom on how to think and apply the knowledge in everyday optimization scenarios.
Who Should Attend
The course is intended for RF engineers, performance engineers, research scientists, PhD students, service and network engineers or anyone looking to learn about LTE RF optimization. The level of instruction for this course is advanced.
The pre-requisites for the course include a firm understanding of the following:
- LTE Architecture
- LTE Air Interface in the Downlink LTE Air Interface in the Uplink
- LTE Configuration and parameters
Upon completion of this course participants will be able to:
- Investigate practically what factors to look for when improving poor throughput in LTE
- Learn five practical ways to start Optimizing LTE network immediately
- Understand how to look at LTE architecture strategically from performance and optimization perspective
- The hierarchical dependence of Key Performance indicators (KPIs) on parameters and performance indicators and how to relate them
- Understand what statistics are collected in LTE network to monitor its performance
- Understand voice over LTE (VoLTE) Delay computation, VoLTE Optimization and user KPIs
The course begins with an introduction to LTE performance management which leads into the anatomy of LTE optimization. In-depth coverage of KPI Analysis for LTE Accessibility, LTE Retainability, LTE Integrity, LTE Mobility, and LTE Utilization are provided as the core of this course’s content. The course concludes with a discussion on LTE System Level Optimization followed by VoLTE Optimization and user KPIs.
