The Wireless Broadband Alliance has released three technical reports proposing how Wi‑Fi, Passpoint and its OpenRoaming federation could be used to support emergency calling and priority communications in indoor, dense public and other challenging environments.
The reports, produced by the WBA’s Mission Critical & Emergency Services Program, set out frameworks and practical guidance for emergency services, public safety agencies, mobile operators, device makers and network providers.
They argue Wi‑Fi can extend traditional mobile services — providing credential‑free emergency calling, SIM‑based VoWi‑Fi extensions via OpenRoaming, and priority lanes for first responders — and improving coverage in dead spots or crowded venues where cellular capacity or signal is limited.
One paper defines an end‑to‑end approach for emergency calling over Wi‑Fi, including network discovery, secure connection and standards‑based location handling so calls can be routed to the correct public safety answering point. A second examines how mobile operators can use OpenRoaming to deliver roaming‑friendly Voice over Wi‑Fi (VoWi-Fi) with sufficient quality of service for emergency calls. The third focuses on national security and emergency preparedness use cases, describing priority, resilience and quality‑of‑service measures for government and emergency agency networks and the role of IoT in critical operations.
Across the three reports the WBA highlights six priorities: treating Wi‑Fi as mission‑critical infrastructure, enabling emergency access regardless of mobile subscription, providing priority access for NS/EP users, integrating OpenRoaming/Passpoint for seamless secure access, improving location accuracy with existing standards, and aligning legal and regulatory frameworks with 3GPP, IEEE and national regulators.
WBA leadership and industry partners framed the work as an effort to make Wi‑Fi a dependable complement to cellular in emergencies. The reports are available from the WBA for agencies and companies considering how to incorporate Wi‑Fi into emergency communications planning.
