Building Resilient Public Safety Connectivity

In this session, Mark will draw on his leadership of the WBA’s Mission Critical & Emergency Services Program to explore how Wi-Fi 6/7 and OpenRoaming can extend resilient, standards-based emergency communications into indoor venues, dense public spaces, and other environments where cellular alone falls short. The talk will address emergency calling over Wi-Fi, National Security and Emergency Preparedness (NSEP) services, and the framework the WBA has developed to help network operators, first responders, and public safety agencies rely on Wi-Fi alongside cellular when it matters most.
