The PBS WARN Project
PBS WARN provides a diverse, redundant path between FEMA and cellular service providers. Using one-to-many satellite distribution and terrestrial broadcast, PBS WARN reaches cellular carriers over-the-air.
If a cybersecurity incident or internet disruption to a carrier facility breaks the primary connection to FEMA, the PBS WARN system provides an immediate alternate source of inbound WEA messages.
Going beyond industry-standard best practices for system design and operation, PBS WARN ensures Wireless Emergency Alerts (WEA) availability to any cellular service provider.
The WARN project is funded by a Department of Commerce grant through the National Telecommunications and Information Administration (NTIA).
