OETA and our infrastructure across the state plays a crucial role in protecting Oklahoma communities by ensuring uninterrupted distribution of Wireless Emergency Alerts (WEAs), including severe weather warnings and AMBER alerts to every corner of the state. This service is part of public television’s commitment to strengthening the safety of all our communities.

PBS WARN (Warning, Alert, Response Network) uses OETA’s unique reach, reliability, and local connections across the state of Oklahoma to provide a vital backup path for the WEA system, which allows local, state and national government agencies (like FEMA) to instantly send short message warnings from geo-targeted cell phone towers directly to a nearby user's mobile device.

If a cybersecurity incident or internet disruption to a carrier facility breaks its primary connection to FEMA, PBS WARN provides an immediate alternate source of inbound WEA messages.
