A spring-like Poznań was the setting for the EuCNC & 6G Summit 2025, celebrated this year in the Polish city from the 3rd to the 6th of June, under the theme: ‘Towards the 6G World’. A “world” to which we, at 6G-REFERENCE, could not avoid travelling, to introduce our preliminary research results with a poster and a scientific publication presentation, while joining discussions on several 6G-related topics with the stakeholders of our ecosystem.
Our innovators are developing 6G hardware enablers for cell free coherent communications and sensing, because we envision a future where urban areas are equipped with sustainable solutions that can cope with the ever-increasing traffic demands and population densification, while providing disruptive capabilities like the materialization of the internet of sense.
We spent most of our time at the event in the Poster Booth 2, or PB2, where our coordinator Centre Tecnològic de Telecomunications de Catalunya (CTTC) was located, represented by the researchers Ignacio Llamas and Zabdiel Brito-Brito. Our booth was our little hub to speak about how we are developing integrated circuit and antenna component solutions, including dynamic frequency filtering and modulated radiation, to enable efficient spectrum coexistence schemes, while also deploying practical hardware enablers in terms of low complexity, cost and power consumption that could end up constituting a reference design for future 6G-distributed radios. It was also a meeting point where we could explain our project activities and network with our partners.
CTTC was joined by the University of Twente, represented by our Technical Manager, Eric Klumperink, and Viswesh Kendae Ramkumar, Doctoral Student, together with Jessica Carneiro and Laura Argilés, from our partner responsible for our Communication and Dissemination activities, AUSTRALO.
We also visited the booth of Smart Networks and Services Joint Undertaking (SNS JU) to get a printed copy of the recently published SNS JU Journal 2025, where you can discover more about the 6G-REFERENCE project in the pages 148 and 149.
The 6G-REFERENCE Radio Frequency Low-Cost Temperature Sensor
“Radio Frequency Low-Cost Temperature Sensor” was the title of our poster presented on Wednesday, the 4th of June, at 12:30h during the lunch break, in the Poster Session I. Zabdiel Brito-Brito, from CTTC, explained that, in this work, preliminary results regarding a radio frequency planar low-cost temperature sensor, with potential for sensing and communications integration, are described. The sensor is based on a ring resonator onto which a layer of PDMS is added as the sensor active layer, allowing resonant frequency shift according to varying temperature since the permittivity of the PDMS changes when exposed to different temperatures.
Poster sessions were a moment in the busy program of EuCNC & 6G Summit to share our 6G projects’ research and results in a more relaxed atmosphere, in this case, during the lunch break.
Besides Zabdiel, our poster was co-authored by Jesús Salvador Velázquez-González, Fermin Mira and Ignacio Llamas (CTTC); and Yi Wang (University of Birmingham).
The 6G-REFERENCE Time Modulated Array and Time Variant Filter Techniques
After Zabdiel explained our research related to radio frequency low-cost temperature sensor, it was the time for our Doctoral Student from the University of Twente, Viswesh Kendae Ramkumar, to get on stage on Thursday, the 5th of June 2025, in the Room 1.E of the EuCNC 2025 to present his scientific article: “Time Modulated Array and Time Variant Filter Techniques to Reduce Receiver Hardware Complexity and Power Consumption“.
His presentation was part of the ‘Session PHY-4: Transceiver Models and Performance’, with a total of six speakers from several universities moderated by Ana García Armada, Professor at Universidad Carlos III de Madrid.
The paper is a collaborative work that also involved Harijot Singh Bindra and Eric Klumperink (University of Twente); and Basem Abdelaziz Abdelmagid and Hua Wang (ETH Zürich), besides Viswesh.
EuCNC & 6G Summit 2025: Towards the 6G World
The 2025 EuCNC & 6G Summit builds on putting together two successful conferences in the area of telecommunications: EuCNC (European Conference on Networks and Communications), supported by the European Commission, and the 6G Summit, originated from the 6G Flagship programme in Finland, one of the very first in its area.
The conference is sponsored by the IEEE Communications Society (ComSoc), the European Association for Signal Processing (EURASIP) and the European Association on Antennas and Propagation (EurAAP), and focuses on all aspects of telecommunications ranging from 5G deployment and mobile IoT to 6G exploration and future communications systems and networks, including experimentation and testbeds, and applications and services. It brings together cutting-edge research and world-renown industries and businesses, globally attracting in the last years more than 1000 delegates from more than 40 countries all over the world, to present and discuss the latest results, and an exhibition with more than 50 exhibitors, for demonstrating the technology developed in the area, namely within research projects from EU R&I programmes.
