IPAWS-OPENEdit
Integrated Public Alert & Warning System Open Platform for Emergency Networks (IPAWS-OPEN) is a IP based network that has integrated the different emergency alert systems of the United States. Its purpose is to connect alert originators to a server which then aggregates and disseminates alerts to the proper systems. IPAWS-OPEN uses CAP.[6]
ProgressEdit
In December 2009, the DHS reached agreement with the Federal Communications Commission (FCC) and the two main telecommunication industry bodies Alliance for Telecommunications Industry Solutions and Telecommunications Industry Association to establish a specification for the interface between CMAS and commercial mobile carriers.[7] Under this agreement, the industry was given a 28-month period to develop, test and deploy a system to allow CMAS alerts to be disseminated to mobile devices. Specifically, the system will allow 90-character SMS to be pushed to all cellphones and pagers in a geographical area, warning of imminent dangers to life or property.[7] The first such gateway was expected to open in early 2011.
In January 2010, the first live code testing of the EAS was conducted in Alaska. The first ever nationwide test of the system took place on November 9, 2011.
In September 2010, FEMA announced IPAWS would be utilizing Open Platform for Emergency Networks (OPEN) to move standards-based alert and information messages between alert and warning systems.[5]
