#  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](/healthcare) to [manufacturing](/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.
