As enterprises deploy a mix of in-building connectivity solutions such as private wireless, CBRS, DAS, and Wi-Fi, understanding the role of Wi-Fi calling is becoming essential. This session examines how Wi-Fi calling complements or competes with other indoor technologies in complex venues including hospitals, campuses, and commercial properties. Panelists will discuss interoperability, handoff behavior, QoS, and security, and explore how owners and integrators can balance cost, control, and user experience while maintaining reliable voice continuity.
