Emergency Alert System for Private Wireless Networks Demo
Why Early Warning Matters
Early warning systems save lives by enabling people to take timely action when notified of impending threats from meteorological, geophysical, fire, or other hazards. Cellular networks deliver warnings to most users, but in deep indoor areas where public cellular coverage is weak, many remain unreachable.
In these cases, users depend on private Wi-Fi or local 4G/5G networks for connectivity. This demonstration service shows how emergency alerts can be extended into such private networks, ensuring users in hard-to-reach areas are still protected.
How This Service Works
This demonstration service enables scalable delivery of emergency warnings. This demonstration system enables private networks to subscribe to receive emergency warning notifications. Using open standards such as Wi-Fi and 3GPP alerting capabilities, networks that opt in can deliver alerts to connected users during emergencies.
This demonstration service is hosted on Amazon Web Services, using dynamoDB to scale the service registrations, and serverless Lambda functions to scale the delivery of notifications.
In the demonstration, an authorized user, likely to be a federal employee in the real world deployment, can POST a JSON object containing a OASIS CAPv1.2 emergency alert message to the service which then triggers the notifications sent to every subscribed private network.
Terms & Conditions
This service is a demonstration system only. It is intended to showcase capabilities for regulators and technology partners. The operator of this service accepts no liability for any issue arising from the transmission or failure to transmit test or simulated emergency alerts. Alerts distributed by this system are not real and should never be relied upon for public safety.
