Wireless Internet: Systems and Applications

The activities of the departments System Design and Circuit Design are focused on this research program.

This program investigates and develops complex systems for wireless communication as prototypes and applications with the objective to find solutions for Hardware / Software systems on highly integrated single chips. The vertical research approach is also reflected in the architecture of the addressed systems. Basically inter-layer interaction is optimized and a vertical migration of semantic elements is performed.

The three major directions of research are systems with high performance, systems with low power consumption and middleware for context sensitive wireless internet applications.

The goal for high-performance wireless systems is to integrate all functionalities of a wireless PDA on a single chip. The targets are to achieve a data rate exceeding 2 Gbps at carrier frequencies of up to 60 GHz. Continuing activities towards data rates up to 100 Gbps will be made in the basic area of this research program.

The research on systems with low energy consumption is directed towards sensor networks based on highly integrated chips. Typical applications are body-area networks for health care or wellness. In this context new network architectures, distributed low resource middleware concepts, new energy efficient protocols for medium access as well as energy efficient transceivers are investigated and realised. UWB transceivers are particularly well suited for short range applications and applications requiring high spatial resolution.

Research in context-sensitive middleware systems addresses especially privacy and security questions in using mobile devices. Moreover the symmetrical and asymmetrical resource distribution between client and server parts of the overall system is investigated.
