Involvement in projects
Since August 1992 Mr. Wietfeld has been member of the Institute's working group 'Dedicated
Short-Range Communications (DSRC) for Road Transport and Traffic Telematics', which is
dealing with the development and performance evaluation of mobile communication systems
for traffic management systems. Mr. Wietfeld has been engaged in the development, formal
specification and performance evaluation of an ISO-OSI conformant communication
architecture for standardized DSRC systems.
Since 1995 he is responsible for technical as well as management tasks within
the European research program 
VASCO (Validation of Dedicated Short-Range Communications).
Mr. Wietfeld is actively involved in the standardization of communication protocols and
application interfaces for the DSRC within CEN TC 278 (European Standardization Body for
Road Transport Informatics) and its corresponding national standardization groups in
Germany. He is the liaison officer for the cooperation between CEN TC 278 WG 9 (DSRC) and
WG 1 (AFC-Automatic Fee Collection). In 1994 he was the member of two EU-funded CEN
project teams dealing with the specification of the DSRC Data Link Layer standard and an
application interface standard for the DSRC link. In 1996, he was member of a CEN project
team defining conformance and interoperability test procedures for DSRC equipment. Since
June 1996, he is the project team leader of a project team defining an application
interface for DSRC-based AFC applications.
Research Interests
His main research interests are the performance evaluations of mobile telecommunication
systems using stochastic simulation techniques and analytical methods. He is also
interested in propagation modelling and antenna synthesis techniques as well as in the
development of run-time efficient road traffic models and formal specification techniques.
Lectures/Courses at
Communication Networks, RWTH Aachen
Mr. Wietfeld was responsible for the exercises of the
lecture on Mobile Communication Networks. He was also involved in the development
of a Multi-media course on the GSM system (Global System for Mobile Communications).
Curriculum Vitae
Mr. Wietfeld was born in Essen, Germany, on January 21, 1966. From October 1986 to July
1992 , he studied electrical engineering at the University of Technology in Aachen. During
his studies he specialized in digital communications and telecommunications. His diploma
thesis deals with the development of optimized code-synthesis techniques for digital
communication systems. He received his diploma in July 1992. In October 1993 he joined the
IEEE Vehicular Technology Society. Dr. Wietfeld is with Siemens now. His address is
