Core 5G and beyond

Individual course

Welcome to learn about the future of 5G on the Core 5G and Beyond MOOC!

On this course you will learn the fundamental concepts behind mobile networks, focusing particularly on 5G and the envisioned future 6G networks. The design, deployment, and management of a mobile network are herculean tasks involving numerous techniques and elements. We aim to present the essential principles and elements to provide understanding and insight into how modern and near-future mobile networks work.

Course contents

  • Chapter 1: Mobile networks. We give an overview of the structure of mobile networks, their creation and standardisation, and key services provided by mobile networks.
  • Chapter 2: 4G networks. To fully understand 5G and beyond, we revisit the 4G architecture that exemplifies crucial design principles and patterns in mobile networks. Many of the mechanisms introduced in 4G can be found in 5G.
  • Chapter 3: 5G networks. We present the key principles and design factors for 5G and illustrate how the 5G networks work.
  • Chapter 4: Towards 6G networks. After investigating 4G and 5G networks, we discuss the design and standardisation of the next mobile network architecture: 6G. This chapter concludes the course.
