Rethinking in-building cellular connectivity for modern enterprise

In this session, CTO Mehmet Yavuz explores why current solutions like DAS and small cells fall short, and how emerging technologies are reshaping in-building mobile coverage.

Enterprises today face a paradox: as buildings become more energy efficient, they also become more resistant to wireless signals. Despite widespread 5G deployment, reliable mobile connectivity inside large buildings remains a challenge, particularly where mid-band 5G signals struggle to penetrate modern materials and where adding new macro cell towers is expensive and slow.

Across industries, from healthcare to manufacturing, IT teams report recurring pain points: dropped calls, inconsistent Wi-Fi calling, limited support for IoT devices, and no visibility into user experience. While solutions like repeaters, small cells, or traditional DAS have served as stopgaps, each comes with trade-offs in cost, complexity, scalability, and upgradeability.
