Welcome to the

Chair of Communication Networks

The Chair of Com­mu­ni­ca­tion Networks (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.  We offer lectures on communication networks, mobile radio networks and the modelling and dimensioning of communication systems as well as entrepreneurial methods.  We kindly invite interested students 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.
