The group's major teaching activities are in the area of mobile and wireless systems. We offer a comprehensive set of lectures, exercises, seminars, and a lab in this area. The courses are attended by students of "information technology" and "informatics" mainly at the graduate level. Furthermore, we offer an undergraduate course on electricity and magnetism and a lab on sensor networks.
Students interested in focusing on mobile and wireless systems should consider the recommendation outlined below:

| Mobile and Wireless Communication Systems |
| Available | Winter and Summer |
| Contact | Christian Bettstetter (VK MWC, VK MWN); Nikolaj Marchenko(KU MWC) |
| Description | The two lectures "Mobile and Wireless Communications" and "Mobile and Wireless Networking" give a bottom-up introduction to the area of mobile and wireless communication systems. The main goal is to give a fundamental understanding of the principles behind wireless transmission and networking. Current technologies, such as UMTS and IEEE 802.11, are used as examples to explain these principles. Moreover, a whole chapter is dedicated to ad hoc networks. The lectures are complemented by five group projects, whose results are discussed in class. A tutorial course with exercises is offered for the winter lecture.

| Network Simulation Lab |
| Contact | Wilfried Elmenreich |
| Description | The goal of this lab is to give an introduction to the simulation of mobile and wireless communication networks using the OPNET modeler. Students simulate wireless LANs based on IEEE 802.11 and mobile ad hoc networks. Thus they are learning how to use a network simulation tool and are also getting deeper insights in how wireless nets are working. Additionally, some more sophisticated areas like network coding, etc. are discussed in this lab. |

| Research Seminar in Mobile and Wireless Systems |
| Contact | Christian Bettstetter |
| Description | This series of seminars covers topics in the field of mobile and wireless communication systems. Based on scientific publications on selected topics students work out technical talks and reports which are discussed in class. Each semester there is an umbrella-topic. While the "Seminar in Mobile and Wireless Systems" addresses state-of-the-art technologies, the "Research Seminar in Mobile and Wireless Systems" addresses latest research trends and requires students to reflect on possible research trends in this area.

| Selected Topics in Network Theory |
| Available | Summer 2009 |
| Contact | Christian Bettstetter, Udo Schilcher |
| Description | In this course the students learn how to theoretically describe, understand and model communication networks. Different tools and models as well as algorithms and phenomenons get discussed. The basic knowledge for understanding the topics tought in this course are presented by the lecturers during the first units. Then the students will prepare selected topics and discuss them in the course units.

| Einführung in das Studium Informationstechnik und aktuelle Fallstudien aus der Praxis |
| Contact | Christian Bettstetter |
| Description | Ziel der Lehrveranstaltung ist, den Studierenden im ersten Semester eine Reflexion der Studienwahl und eine Sensibilisierung für die berufliche Zukunft zu ermöglichen. Ein wesentlicher Bestandteil der Lehrveranstaltung sind fünf Referate durch Experten, die im Bereich der Informationstechnik arbeiten. Diese referieren über aktuelle Fragestellungen in ihrem Fachgebiet. Dadurch soll den Studierenden u.a. vermittelt werden: Welche Fragestellungen gibt es im Bereich der Informationstechnik? Welche Aufgaben nehmen Ingenieurinnen und Ingenieure der Informationstechnik wahr?
Ergänzt wird die Lehrveranstaltung durch eine Einführung in das Studium Informationstechnik, in der der Aufbau des Studiums erklärt wird und ein kurzer Abriss über deren Inhalte gegeben wird. Schließlich werden zu ausgewählten Themen Gruppenarbeiten vergeben, die gegen Ende des Semesters in der Vorlesung vorgestellt werden.
