  • Auf dem Weg zur KI-unterstützten Netzautomatisierung: Verkehrsprognose-basierte, lastadaptive Steuerung der optischen Linkkapazitäten

    Fraunhofer HHI – In diesem Blog Post wird eine Methode zur dynamischen Anpassung der Verbindungskapazität auf der Grundlage von ML-gestützten Verkehrsprognosen für optische Metro-Aggregationsnetze vorgestellt. Die Methode wird auch mit der traditionellen statischen Zuweisung von Verbindungskapazitäten verglichen. Es zeigt sich, dass die dynamische Anpassung der Verbindungskapazität die Kapazitätsüberversorgung deutlich reduzieren kann und damit Einsparungen bei…

  • Trend reversal in the demand for electricity in Germany’s ICT sector by 2033

    There are currently signs of a trend reversal in the demand for electricity in ICT. According to calculations carried out by Fraunhofer IZM, the annual demand for electricity in ICT is rising again since 2023, from around 50 TWh to over 72 TWh in 2033. In a recent study, Dr. phil. Lutz Stobbe and his team model the environmental impact of the production and use of information and communication technologies (ICT) in Germany over a period from 2013 to 2033. The ICT study was commissioned by the Federal Ministry of Education and Research (BMBF).

  • RISC-V Core "AIRISC" from Fraunhofer IMS: Hardware acceleration for energy-efficient AI on edge devices

    Fraunhofer IMS - In the future, smart sensor technology will be used to process the measured values locally with the help of AI or to adapt to changes in the environment. In the "Green ICT @ FMD" project, scientists at Fraunhofer IMS are working on the energy-efficient implementation of AI algorithms. The RISC-V processor AIRISC ( has therefore been enhanced with instruction set extensions and coprocessors for the extremely efficient calculation of neural networks.

  • III/V semiconductor layers on silicon substrate

    Fraunhofer IAF - As part of Green ICT @ FMD, IAF is working on the development of a process for the production of III/V semiconductor layers on Si substrates to minimize the arsenic content in components. For the qualification of the substrate transfer process, InGaAs amplifier ICs on silicon substrates with excellent maximum frequency properties could be realized.

  • mioty® - Wireless communication technology for energy-autonomous sensors

    Fraunhofer IIS - The increasing demand for wireless remote-readable sensors, such as in smart metering applications, requires a resource-efficient realization. In the Project Green ICT @ FMD, scientists at Fraunhofer IIS are working on energy-autonomous sensors. A key element here is radio communication. With measurements in the lab, Fraunhofer IIS scientists can determine the energy requirements of various radio technologies in different application scenarios and compare them to find the most energy-efficient solution. High energy efficiency and immunity to interference characterize the mioty® radio communication developed by Fraunhofer IIS.

  • GaN Power ICs - Components for more sustainable ICT power systems

    Fraunhofer IAF – Many low-voltage power electronic applications are transitioning to gallium nitride-based devices, which can increase the system's energy efficiency and power density. Within the Green ICT @ FMD project, scientists at Fraunhofer IAF investigate how gallium nitride can be used for more sustainable and resource-efficient ICT power supply systems.

  • Signal processing on the edge – µController-based radar back-end structure 

    Fraunhofer FHR – The FHR has developed a new back-end structure for its radar sensors, which can be switched off, extended, and reconfigured at runtime by their master/slave configuration. In addition, signal processing by interpolation has been adapted so that it can be performed directly "on the edge" on the µController.

  • Increasing the sustainability of semiconductor manufacturing processes

    Fraunhofer EMFT – Around 80 % of the CO2 footprint of average electronic components is already caused during production. A research team at the Fraunhofer EMFT is working on optimizing processes in semiconductor production in order to minimize the use of climate-damaging process gases. In the process, the scientists are also testing more climate-friendly alternatives to etching gases that have been used as standard to date.
