Module Overview

Contact School for details.

Module Aims

The aims of the module are

  • to equip the students with the knowledge of mobile/personal communications engineering fundamentals
  • present the problems and possible solutions
  • to familiarise them with the currently operational digital mobile communication systems in Europe, North America, Japan and the rest of the world and their comparisons, as well as the standardisation activities on future systems.
Learning Outcomes

By the end of the module, students will be able to

  • leave the MSc course with the knowledge and ability to take on jobs within the mobile communications industry and quickly perform a useful role in analysing, designing or managing mobile communication systems,
  • or to enter an advanced research programme on this topic
