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.
