Work Package 5 (WP5) of the COREnext project focuses on improving the reliability and performance of communication links through the development of analogue components. By leveraging hardware imperfections and advancing ultra-high-speed interconnect technologies, WP5 aims to provide secure and energy-efficient solutions for next-generation communication systems.
Enhancing Radio Link Trustworthiness
A significant focus of WP5 is the development of Radio Frequency Fingerprinting (RFF) technology. This method uses inherent hardware imperfections to enhance the reliability and security of radio links. Necessary training to validate RFF concepts data are obtained from software and hardware platforms covering different frequency bands, namely a sub-6GHz software-defined-radio, a sub-10GHz transmitter testbench and a sub-THz multiuser MIMO simulation platform. The latter one is furthermore designed to evaluate link robustness to imperfections and security threats such as eavesdropping in the challenging D-band.
Advancing Ultra-High-Speed Interconnects
WP5 is making progress in developing short-range, high-speed data communication using Plastic Microwave Fibres (PMFs). These fibres offer a practical alternative to traditional interconnects due to their low cost, reduced energy consumption, and adaptability to high-frequency ranges such as the H-, Y-, and D-bands. Recent achievements include the design and prototyping of integrated transmitters and receivers using advanced BiCMOS processes. Measurements have shown data transmission rates of up to 102 Gbps in the D-band and 30 Gbps in the Y-band. Additional work has focused on developing packaging solutions, including 3D-printed PMF holders and low-k material designs, to enhance integration and efficiency.
Sustainability and Industry Impact
WP5 also aligns with sustainability objectives by proposing means to reduce energy consumption and adopting environmentally friendly materials. For instance, the use of PFAs-free materials in PMFs addresses environmental and health concerns associated with traditional materials. Furthermore, a patent application has been submitted for the RF Fingerprinting authentication method, which highlights its potential to contribute to industry standards and practices. The work undertaken in WP5 supports an increase in technology readiness levels (TRLs) and creates opportunities for applications in secure and efficient communication hardware.
WP5’s developments in analogue components contribute to improving the trustworthiness and performance of communication systems. By addressing both security and operational efficiency, the results of this work support the foundation for reliable and energy-conscious networks in the 6G era.
