IPQ participates in Open6GHub Germany

Reliable and high-performance communication networks are of great importance for our society. 6G is envisioned to serve as the infrastructure for future mobile applications based on artificial intelligence (AI).

In the Open6GHub Germany, 17 partners, including the Karlsruhe Institute of Technology (KIT), are working on the development and implementation of intelligent communication networks and the next generation of mobile communication networks. The German Federal Ministry of Education and Research (Bundesministerium für Bildung und Forschung - BMBF) is funding the project with nearly 67 million euros.

The research group led by Prof. Randel will set up an ultrabroadband modem for Terahertz communications. In this context, system concepts for terahertz data transmission with holistic optimization of digital and analog parts will be studied. An essential part of this work is the investigation of novel digital signal processing algorithms and the hardware design of real-time capable algorithms on FPGA platforms. Finally, the THz-modem will be demonstrated in field experiments. In addition, the group will study radio-over-fiber networks in the context of a 26-GHz MIMO-antenna test field.

The research group of Prof. Koos participates in the hub with its extensive expertise in the field of integrated photonics for the direct fiber-optic connection of terahertz access points to the fiber-optic network. Optical components such as tunable external cavity lasers, photonic multiplexers, electro-optic modulators for the direct THz-to-optical signal conversion and 3D-printed THz-structures are investigated and developed. Finally, the components are integrated into hybrid multi-chip transmitter and receiver modules using sophisticated 3D-printing techniques and are validated in system demonstrations.
