To the Communication Networks Institute

Welcome to the

Communication Networks Institute

The Com­mu­ni­ca­tion Networks Institute (CNI) focuses on the re­search and development as well as the quantitative analysis of cutting-edge com­mu­ni­cation services, network architecture and their protocols. CNI has been led by Prof. Dr.-Ing Christian Wietfeld since 2005. With our numerous collaborative research projects, we contribute to the evolution of future wireless communication systems, in particular 5G+ and 6G networks, which are suited to fullfill challenging requirements in application fields like rescue robotics, automotive, smart grids, and the internet of things. 

The result of our research is documented in a wide range of publications, which have received a number of international awards. The impact of our research strongly builts on the integration of most recent machine learning techniques derived from our participation in the Collaborative Research Centre SFB 876 as well as on our excellent lab environment, which includes a mobile lab for experiments in the field, an outdoor testing site on the roof-top of a university building as well as access to unique test fields, such as the German Rescue Robotics Centre located nearby. 

We offer lectures on communication networks, mobile radio networks and the modelling and dimensioning of communication systems as well as entrepreneurial methods  in the field of Information & Communication Technology (ICT). The course catalog is supplemented with numerous practical labs.  We kindly invite interested students to to built up in-depth expertise mobile communication networks by joining our team as student assistant and by working on their final theses with us.
