The main research focus of the ComNets group at the University of Bremen is performance analysis of communication networks and their protocols. This includes the implementation of prototypes as well as performance studies by mathematical analysis and simulation. The main keywords are: mobility support, mobile communications, wireless communications, simulation technology, rare event simulation, teletraffic engineering. Research projects are mainly funded by national and international government institutions and direct industry collaborations. The group around C. Görg consists of one senior scientist and about 10 fully employed research assistants, a small technical and assisting team and many students working as student workers or doing their thesis.

Dr. Mathias Hoder, Detecon: Trends in wireless communications
The market of wireless communications is changing drastically. Saturated mobile markets change the whole value chain. With the fast evoution of technologies new players enter the market, mobile products are bundled with other consumer products and the incumbent operators suffer shrinking profit margins. Ideas for really new services are rare. On the other hand smart terminals enable terminal based services; they only require access to the Internet.
The presentation illustrates the new value chain. It furthermore summarizes important technological developments which in turn enable that market change. The position of the Internet / terminal based services and on the other hand the position of the incumbent operators are compared and discussed. Finally, an outlook on the organisational impact for the large operators will be given.
