QoS and QoE of LTE and 5G Networks

Teacher

Christine Chua

Category:

Network Planning & Optimization

Communication network powered by LTE and 5G networks

Target Audience

Regulators and telecommunications personnel who require a strong knowledge of LTE, LTE-A, VoLTE, VoIP, IMS, 5G technologies and mechanisms
Personnel in charge of telecoms regulation and the configuration and monitoring of a 4G or 5G network
Operations and maintenance personnel who are required to understand LTE and how 4G and 5G function
All regulators, engineers, technicians and managers working with LTE 4G, 5G, GSM, UMTS, Wi-Fi, LTE technology

Course Objectives

At the end of the course, participants will learn and understand:

What is QoS (inward looking, network oriented) and QoE (outward looking, customer focused)
How to measure QoS and QoE in mobile networks
How QoS is based on technical and lower layer parameters in RF, signaling, and IP
How QoE often uses events on application layer or above
QoS parameters that allow users to efficiently spot technical problems and bottlenecks in the network
How QoE provides an end-to-end view and is often based on perceptual feedback given by a user

Duration & Training Format
