Industry Projects

Our projects are designed by experts in the industry to reflect industry standards. By working through our projects, Learners will gain a practical understanding of what they will take on at a larger-scale in the industry. In total, there are 2 Projects that are available in this program.

Customization of LTE-Sim

The LTE project is based on the customization of “LTE-Sim” an open-source framework to simulate LTE networks. The developed LTE-Sim encompasses several aspects of LTE networks, including both the Evolved Universal Terrestrial Radio Access (E-UTRAN) and the Evolved Packet System (EPS). It supports single and heterogeneous multi-cell environments, QoS management, multi-user environment, user mobility, handover procedures, and frequency reuse techniques.

Configuration of an LTE Network

The project is based on open5gs, an open-source EPC and 5G Core platform. This project can be used to configure your own LTE network. With this project you can create different scenarios, test them and analyse them. Open5GS implemented EPC using C-language.
