This article is based on session discussions from the Marconi Society Advanced Wireless Forum, with insights and post-event reflections contributed by Andrew Clegg, Chief Technology Officer, Valo Analytica

At the Marconi Society’s Advanced Wireless Forum, a panel of industry and academic leaders explored the evolving landscape of wireless infrastructure—focusing on how to integrate diverse technologies into a seamless, efficient, and economically viable network architecture.

The session, moderated by Vicente San Miguel of Open Vision Partners, brought together perspectives from across the ecosystem, including Andrew Clegg (Valo Analytica), Matti Latva-aho (University of Oulu), Greg Pelton (Iridium Communications), and Yago Tenorio (Verizon).

The Integration Challenge

Wireless connectivity today is inherently fragmented—Wi-Fi dominates indoors, cellular networks serve wide-area mobility, and satellite systems extend coverage to remote regions. The panel centered on a critical question: how do we unify these layers into a heterogeneous architecture that delivers a truly seamless user experience?

While technological pathways exist, panelists emphasized that integration is not just a technical problem—it is equally shaped by policy, economics, and deployment strategy.

Spectrum Policy and Economic Reality

A recurring theme was the growing tension around spectrum policy. Current approaches—particularly in the U.S.—were described as increasingly unsustainable, with a heavy reliance on clearing and auctioning spectrum at ever-higher frequencies.

Panelists noted that this strategy may be misaligned with real-world needs. Higher frequencies, while capable of delivering higher throughput, often result in weaker coverage—especially indoors, where the majority of usage occurs.

There was also skepticism around emerging models like direct-to-device satellite connectivity. While compelling in theory, questions remain about long-term return on investment, particularly for unmodified consumer devices.

From a European perspective, the traditional “generation-by-generation” investment cycle (e.g., 4G → 5G → 6G) was viewed as economically untenable. Instead, panelists stressed the need for deployment models that are financially viable from the outset—not dependent on speculative future use cases.

Coverage Over Throughput

Drawing from his post-event reflections, Andrew Clegg emphasized a fundamental shift in priorities: in developed markets, improving coverage—not peak data rates—should be the primary goal.

He highlighted the inefficiency of current indoor coverage models, where signals from outdoor base stations attempt to penetrate buildings, losing the vast majority of their energy in the process. A more effective approach, he suggested, would be greater use of indoor small cells that reuse existing spectrum—dramatically improving efficiency and user experience.

Hype vs. Practicality: ISAC, AI, and 6G

The panel also examined emerging industry trends:

• Integrated Sensing and Communications (ISAC): While widely discussed, questions remain about whether real-world applications will justify the current level of enthusiasm. 
• Artificial Intelligence in Networks: AI holds clear promise for improving network performance—particularly in modeling, monitoring, and predictive maintenance. However, its impact on driving new traffic demand is less certain. 
• 5G and 6G Evolution: There was a candid acknowledgment that next-generation technologies can sometimes feel like “solutions in search of a problem.” Panelists stressed the importance of aligning technological advancement with meaningful applications and developer ecosystems. 

A Key Takeaway – Bridging the Gap Between Engineers and Applications

A key takeaway was the need for stronger collaboration between those building wireless infrastructure and those creating the applications that run on it. Without this alignment, even the most advanced networks risk underutilization.

Future success, the panel suggested, will depend not just on better technology but on a more integrated approach across the entire innovation chain.
