Last Updated: 2026-02-05 15:13:56
Abstract
The term wireless communications merges a large number of very different systems. This lecture allows a broad overview over current and future wireless communication systems and the implementation of fundamental principles of wireless communications. In parallel, market analyses shall help to measure the state of the art of these systems with respect to production, development and research.
