Objectives

Upon successful completion of this module, students are able to
1. Describe the evolution of mobile communication standards.
2. Explain the functions of enabling technologies such as MIMO and SDN in mobile networks.
3. Apply knowledge of 5G architecture to identify the structural and functional interplay between the Radio Access Network and Core Network elements.
4. Analyze mobility management and security mechanisms in mobile communication systems.
5. Evaluate emerging trends in next generation mobile networks.

Description

This course has been designed to serve as an introduction to mobile communication technologies with a focus on 5G architecture and enabling technologies. In detail, the following topics are covered:
• Basic concepts of mobile networks
• Technology enablers of mobile networks
• 5G architecture - Radio Access Network (RAN)
• 5G architecture - Core Network
• Mobility management in mobile networks
• Security in mobile networks
• Future aspects of 6G networks

Prerequisites

Basic knowledge of wireless networks
Principles of OSI layers

Teaching and learning methods

The module combines various teaching and learning methods to support a structured and student-centered learning experience. Each session begins with short quizzes using polling tools to recall previous lessons. Core content is delivered through teacher-centered lectures that introduce key concepts in mobile communications. Students work on exercises independently before class and based on their results, they complete a quiz on Moodle assessing their understanding. In class, the quiz answers are discussed collaboratively to address misconceptions and deepen comprehension. Think-pair-share activities are used to encourage reflection on the day’s concepts. Hands-on exercises provide practical experience with mobile network technologies. To connect theory with future developments, students read selected scientific papers on emerging applications in mobile networking.

Examination

The module examination consists of a graded written exam of 90 minutes conducted at the end of the semester and graded homework exercises (8-9 sets) completed throughout the course.

In the written exam, students demonstrate their understanding of the theoretical concepts of mobile communication networks by solving problems and answering open questions that require both conceptual clarity and analytical reasoning.

In the homework exercises, students demonstrate their practical skills by completing self-study assignments followed by quizzes on Moodle. These exercises allow the students to show their ability to apply course concepts in various formats, including written problem-solving and software-based analysis using tools such as Wireshark. This continuous assessment approach supports progressive learning and reduces exam pressure.

The final grade is composed of the following components:
• 60% from final exam
• 40% from homework exercises
