News & Updates

IPAWS is pleased to announce the availability of IPAWS TSS 24 hours a day, 7 days per week, including holidays. The new toll-free number for the IPAWS Lab is 1-84-IPAWSLAB or 1-844-729-7522.

For several years, requests from Alerting Authorities have grown to include the availability of IPAWS Lab technical assistance after business hours. We have met the demand, and the IPAWS Lab will continue to provide a closed/safe environment for Alerting Authorities to improve alerting proficiency, assess operating procedures, train employees, and exercise processes.

IPAWS is pleased to announce that the Mandan, Hidatsa, and Arikara Nation, also known as the Three Affiliated Tribes, were brought on board as our newest of 8 Tribal Nations to become an authorized Alerting Authority! We applaud the efforts of everyone who has made this pivotal moment a reality!

As of today, there are 8 Tribal Nations authorized to use IPAWS:

  • Cocopah Indian Tribe
  • Navajo Nation
  • Hualapai Tribe
  • Rincon Band of Luiseno Indians
  • Eastern Band of Cherokee Indians
  • Ysleta del Sur Pueblo
  • Confederated Tribes of the Chehalis Reservation
  • The Mandan, Hidatsa, and Arikara Nation, also known as the Three Affiliated Tribes

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.

The Integrated Public Alert and Warning System (IPAWS) - Open Platform for Emergency Networks (OPEN) architecture diagram. Using a Common Alerting Protocol (CAP) compliant software tool, alerting authorities create a message and send to IPAWS - OPEN. IPAWS - OPEN then routes the message to private industry infrastructure for dissemination as a Wireless Emergency Alert (WEA), through the Emergency Alert System (EAS), through NOAA Weather Radio, through Internet Based Services, and Unique Alerting 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.
