This course is designed to qualify radio network engineers to effectively perform the dimensioning and tuning of LTE network capacity. It covers aspects of design, dimensioning, monitoring and fine-tuning the network. Throughout this course, various use-case examples are analysed, as well as hands-on exercises, in order to improve knowledge retention. 

Who should attend

This advanced technical course is better suited for telecom professionals working on LTE radio network performance, planning and optimization. System integrators and solution managers can also benefit of getting in touch of common problems found in real networks and ways to minimize/solve them.

Prerequisites

Solid background of LTE/EPS concepts, architecture, terminology and E-UTRAN implementation is required prior to this course. Although it’s a deep technical course, participants are also provided with relevant theory \aspects required to better appreciate the course. It’s recommend, but not essential, to have attended before other courses such as: Planning the LTE Radio, Optimizing the LTE Radio and LTE Radio Network Performance and Optimization.

LTE is around for long time now and one major problem operators faced currently is the network capacity. With the advent of flat rates and mobile apps, users’ demanded traffic has increased tremendously over the past few years, including more and more use of VoLTE. Networks have to deal with this huge traffic demand without compromising QoS requirements.
