Integrated Public Alert & Warning System

The Integrated Public Alert & Warning System (IPAWS) is FEMA's national system for local alerting that provides authenticated emergency and life-saving information to the public through mobile phones using Wireless Emergency Alerts, to radio and television via the Emergency Alert System, and on the National Oceanic and Atmospheric Administration's Weather Radio.

How IPAWS Sends Alerts

IPAWS allows Alerting Authorities to write their own message using commercially available software that is Common Alerting Protocol (CAP) compliant. The message is then delivered to the Integrated Public Alert and Warning System, Open Platform for Emergency Networks (IPAWS OPEN), where it is authenticated and then delivered simultaneously through multiple communication pathways. Through IPAWS, one message is created to reach as many people as possible to save lives and protect property.

Utilizing multiple pathways for public alerts increases the likelihood that the message will successfully reach the public. IPAWS is structured to facilitate this functionality.

Diagram shows Alerting Authorities consisting of local agencies, state-wide agencies, tribal governments, territorial agencies, and federal agencies initiating requests through IPAWS OPEN to send alerts, warnings, and notifications via the Emergency Alert System, Wireless Emergency Alerts, NOAA Weather Radio, Internet-Based Services & unique state and local alert systems.

Communication Pathways

The Emergency Alert System (EAS) delivers alerts via AM, FM and satellite radio, as well as broadcast, cable and satellite TV.

Cell phones and mobile devices receive Wireless Emergency Alerts based on location, even if cellular networks are overloaded and can no longer support calls, text and emails.

The National Oceanic and Atmospheric Administration (NOAA) delivers alerts through NOAA Weather Radio.

Alerts are also available from internet service providers and unique system developers.

State, local, territorial, and tribal alerting systems such as emergency telephone networks, giant voice sirens, and digital road signs may also receive alerts from IPAWS-OPEN, and future alerting technologies and systems can easily be integrated into IPAWS.
