Rheinisch-Westfälische Technische Hochschule Aachen

The Chair for Theoretical Information Technology (TI) is headed by Univ.-Prof. Dr. rer. nat. Rudolf Mathar. There are 30 full time employees, including 24 scientists. The areas of research comprise information theory, design, optimization and control of mobile networks and sensor systems, interference management for wireless systems as well as applied statistical methods in information and communication technology.

Methodically emphasis is laid on mathematical modeling and analysis of information and communication systems. The expertise of TI consists of developing sufficiently precise models, appropriate for describing reality and allowing for solutions of underlying optimization problems either analytically, by efficient algorithms or with powerful heuristics, which approximate the optimal solution. Applications include developing solutions for SON (self-organizing networks) and planning mobile networks from 2G to 5G. For this purpose, accurate radio wave propagation tools have been developed based on ray optical models and combining stochastic channel models with concrete environmental data.

In the BIC-IRAP project, the RWTH tests, validates and calibrates 3D-dispersion models. Moreover, the RWTH is part of the development of the small-cell compounds, in which she, e.g., tests decentral SON control procedures.
