Welcome to the Chair of Communication Networks

Prof. W. Kellerer

Communication networks provide a cross cutting function across many disciplines in todays information society. Research and teaching of the Chair of Communication Networks (in German: Lehrstuhl für Kommunikationsnetze, LKN) focus on methods and systems for mobile and fixed communication networks as an infrastructure for future Internet communication. Our core competences are architectural concepts, control and management mechanisms, self-organization principles, methods for optimization and performance evaluation as well as techno-economic analysis.  

On our website, we present an overview of our current research activities and selected results. More details can be found on the individual home page of each researcher.

LKN is a member of the compentence centers COMMUNICATION, ROBOTICS and POWER SYSTEMS.


To address the dynamic change in communication networks regarding strongly increasing bandwidth requirements, extremely low latencies and high resilience (keywords include here: "5G" and "Tactile Internet"), novel methods and algorithms as well as concepts for protocols and network architectures are required.

Current research areas include

  • Flexible, dynamic networking based on Software Defined Networking and Network Virtualization
  • Resource management in wireless networks: Device-to-Device Communication, machine-type communication, wireless sensor networks
  • Network planning and techno-economic analysis of converged networks

Please see details on our research page.




We offer the following courses:

  • 2 B.Sc. lectures: Communication Networks, Internet communications (in German)
  • 7 M.Sc. lectures: Broadband Communication Networks, Optical Networks, Network Planning, Techno-Economic Analysis of Telecommunication Networks, Analysis, Modeling and Simulation of Communication Networks, Communication Network Reliability
  • 5 lab courses: Communication Networks, Wireless Sensor Networks, Industrie 4.0, Tactile Internet Lab, Software Defined Networking Lab
  • 4 seminars

We offer several Bachelor and Master Thesis projects in each semester, as well as projects for "Ingenieurspraxis" and "Forschungspraxis". If you are interested, please see our topics list contact a member of the research staff or Prof. Kellerer.



Together with the Chair of Media Technology (Prof. Dr.-Ing. Eckehard Steinbach), we form a research and teaching unit.
