In an increasingly connected world, data demand is growing exponentially. To meet this challenge, the Glemoris project focuses on the development of reconfigurable intelligent surfaces (RIS) as a key technology for the next generation of wireless communications. This technology enables dynamic adaptation of signal transmission to significantly increase the efficiency and capacity of communication networks.

The main objective of the Glemoris project is to develop a novel, energy-efficient RF switch capable of meeting the signal transmission requirements of 6G networks. By using advanced CMOS technology and innovative design methods, we will maximize the energy efficiency of the components used while improving communication quality.

The project is being carried out in close cooperation between National Chung Cheng University (CCU) in Taiwan and the Fraunhofer Institutes IPMS and HHI in Germany. The partnership is intended not only to promote technological advances, but also to facilitate exchanges between students and researchers. These international experiences will strengthen the innovative power of the project partners and promote the exchange of knowledge.

Key objectives:

  1. Development of an energy-efficient RF switch: The aim is to reduce the switch's power consumption to less than 1 W while achieving high performance and fast switching times.
  2. Integration of RF switches into RIS elements: The development of control algorithms for dynamic adjustment of signal transmission will increase the efficiency and flexibility of the system.
  3. System testing and validation: Extensive testing in real-world scenarios will be conducted to demonstrate the performance of the developed technologies.

Collaboration and exchange

A central component of the project is the exchange of students and researchers between Taiwan and Germany. This exchange will not only expand technical knowledge, but also strengthen international cooperation and broaden the cultural perspective of the participants.

Project results and prospects

The expected results of the project include not only technological innovations in the field of RF communication, but also the development of new training formats and technologies that will be crucial for future applications in smart cities and IoT networks. The Glemoris project is thus positioning itself as a pioneer in the development of sustainable and powerful communication technologies for the future.

Fraunhofer IPMS in project GLEMORIS

Fraunhofer IPMS brings extensive expertise in the development and characterization of integrated circuits (ICs), particularly in the field of ultra-low power RF switches. As part of the Glemoris project, IPMS will take the lead in designing and implementing the ICs that are crucial for Reconfigurable Intelligent Surfaces (RIS). Research will focus on the development of CMOS switches that enable a significant reduction in energy consumption without compromising performance.

A key objective of IPMS is to design innovative circuits that are specifically optimized for the requirements of 6G networks. These switches will not only reduce energy consumption to less than 1 W, but also achieve a high switching speed of less than 1 µs for RF controls. These switches are characterized using state-of-the-art measurement methods in the in-house laboratories, which enable precise evaluation of performance parameters in realistic scenarios.

In addition, Fraunhofer IPMS will support the integration of the developed ICs into the RIS modules to ensure that the systems are optimally tailored to the respective communication requirements. Through close cooperation with partners in Taiwan and the implementation of system tests, IPMS will make a significant contribution to achieving the technological goals of the Glemoris project and laying the foundations for future applications in wireless communication.
