Engaged in Dialogue: BI at Numerous Conferences in the Third Quarter of 2025
Our researchers present their work at conferences to make it accessible to an international expert audience, to receive feedback, and gain new insights through scientific exchange. In the third quarter of 2025, they were once again active at numerous conferences.
Two examples of BI’s international activities in the third quarter of 2025 are the 6G Conference and the OSDI Conference.
6G Conference
At the 6G Conference in Berlin (July 1–3, 2025), BI researchers presented a wide range of demonstrators, talks, and workshops.
Dr.-Ing. Muhammad Umar and Dr. Sajjad Ahmad from the RF Design Enablement research group showcased our Joint Communication and Sensing demonstrator. The underlying technology is based on BI’s long-standing expertise in chip design, PCB packaging, antenna technology, and baseband processing – developed with the support of our open-source simulator HermesPy.
Dr.-Ing. Stefan Köpsell led two workshops: “Trustworthiness of and by AI/ML for 6G” and “Trustworthiness of Joint Communication & Sensing (JCAS).” He also took part in the panel “From Research to Reality: Implementing Trustworthiness in 6G Networks.” The focus was on technical solutions and the needs of future users – with the aim of embedding trust as a core element of 6G systems. Participants gained valuable insights and practical strategies for implementing 6G.
The Trustworthy Data Processing research group presented three demonstrators: The “CampuSens AGV Rollercoaster” used Lego® roller coasters to simulate Automated Guided Vehicles (AGVs), illustrating post-quantum secure Digital Twins and Asset Shells. “Post-Quantum Secure Communication for Cooperative Radars”, a joint project with NXP, showed how radar data can be protected in a privacy-preserving way without limiting safety-critical functions such as geofencing. “Ready for Critical Use?!”, developed within the 6G-ReS project, demonstrated the reliability of 5G/6G systems even in crisis situations – even when components from untrusted manufacturers were used.
As co-leader of the 6G Platform’s Science Communication working group, Carolin Fischer organized both a session and a booth. The session “Let’s Talk 6G: Trust, Transparency, and Science Communication” featured contributions from Christian Raupach of the Federal Office for Radiation Protection and Flavia Maragno of the 6G4Society project. The discussion centered on what constitutes “good” public outreach for complex topics such as mobile communications. At the information booth, ideas and materials were provided to inspire and support researchers in designing and implementing their own communication projects.
Prof. Gerhard Fettweis, Scientific Director and Managing Director of the BI, discussed the topic “6G technologies in the context of healthcare.” He also chaired the two sessions “Extreme MIMO in 6G – Challenges and Opportunities” and “Plenary Keynote Session.”
19th USENIX Symposium on Operating Systems Design and Implementation (OSDI)
At the 19th USENIX Symposium on Operating Systems Design and Implementation (OSDI) in Boston, MA, USA (July 7–9, 2025), our researcher Dipl.-Inf. Till Miemietz presented the paper “MettEagle: Costs and Benefits of Implementing Containers on Microkernels.”
The paper compares how secure and efficient containers run on different operating systems. On conventional systems like Linux, many additional mechanisms are required to isolate applications from one another, which makes the kernel, the central core of the operating system, more complex and more vulnerable to attacks. Microkernel systems do not require these additional mechanisms because they are fundamentally different – by design. With the prototype MettEagle, the researchers demonstrate that containers on a microkernel (L4Re) can run just as fast or even faster than on Linux – while providing greater security at the same time.
