Day 1: A Dynamic Start with Exciting Innovations
The first day of MWC 2025 kicked off with a wealth of impressive technologies and inspiring keynotes. Felix highlighted the incredible diversity of innovations on display—from advanced networking solutions and artificial intelligence to new developments in the Internet of Things (IoT).
One standout feature was the strong presence of startups including xG-Incubator’s own MOXZ, airpuls and Massive Beams, bringing creative solutions to shape the future of the world of telecommunications.
Day 2: A Morning Bike Ride & Deep Dives into 5G Developments
Felix started his second day with a morning bike ride along Barcelona’s coast—a refreshing break before diving back into the exhibition halls. The rest of the day was devoted to exploring innovations from the UK, Switzerland, hubraum, and the Berlin-Brandenburg stand. He highlighted Matterway’s software for automating repetitive tasks, ideal for Germany’s e-file system, and met with IS-Wireless to discuss private 5G networks for industrial use. At the Swiss stand, Felix was impressed by INFRAVISTA’s remote network monitoring, nu glass for improved 5G signal, and Synthara AG’s high-performance computing.
He also enjoyed the Korean startup Pebblous’ AI-driven data quality improvement and attended a panel on satellite-based connectivity, including solutions from Ramon.Space and FOSSA Systems. Felix shared pitching tips and had insightful discussions on eSIM solutions and upcoming news from Cambridge Wireless Ltd.
Day 3: Networking and Showcasing Berlin’s Innovation Strength
Felix spent the third day at MWC 2025 focusing on the Berlin-Brandenburg stand, engaging in inspiring conversations with various exhibitors.
Highlights included TECTWIN’s scalable solutions for creating digital twins and simulating network coverage for 5G/6G environments, MOXZ’s technology for train communication and location tracking in Berlin’s subway, and AVOW’s success in app marketing. He also discussed m4 wireless GmbH’s breakthrough in metamaterials for antennas and Equative Solutions’ seamless ad integration technology.
Felix was excited about the visit from Galina Gorshkova, who generated new leads at the Open-Mic stage. He also explored Li-Fi technology with Fraunhofer HHI, which offers wireless connectivity in areas where traditional wave technologies aren’t ideal.
Day 4: Future Trends and a Look Ahead
Felix’ fourth and final day at MWC 2025 included insightful conversations with Dragos Vingarzan from Neat Path Networks about VoLTE solutions for private 5G networks, and Robert Elschner from Fraunhofer HHI about THz connections as alternatives to fiber. At the European Innovation Council booth, he discovered BeammWave’s digital beamforming for mm-wave technology, and was surprised to learn that Swisscom is the largest drone operator in Switzerland, with drones potentially becoming a new telecom business model.
Felix also revisited his optics background with NIL Technology’s diffractive lenses. In his conclusion, he praised the innovation at the Berlin-Brandenburg stand, highlighted Europe’s strengths in innovation, but emphasized the need for more focus on serial production and funding. He called for better networking among German innovators to unlock synergies:
“Innovation is strong in Europe, but serial production is lacking.
Financing remains a critical factor: EIC and programs like SPRIND—the Federal Agency for Disruptive Innovation—are crucial for follow-up financing and balancing the US VC market. This way, we prevent our hard-earned technologies (such as the DACs from InCirT) from leaving too early for the US.
More networking among German innovators could unlock significant synergies. I continue to advocate for us to get to know each other better and benefit from one another.”
Conclusion: MWC 2025 as a Platform for the Tech World
Once again, the Mobile World Congress 2025 provided a unique platform for discussing the future of telecommunications and digitalization. Topics like 5G, AI, IoT, and Open RAN dominated discussions, offering a glimpse into how the industry will evolve in the coming years.
For Felix Willems, the event was an inspiring experience - MWC 2025 has once again demonstrated that technological innovations don’t happen in isolation but in collaboration between research, startups, established companies, and investors.
