When disasters strike – like the LA and Lahaina wildfires to Hurricanes Helene and Milton - the country's cellular networks and internet connections have often failed to deliver important safety alerts and information. When seconds count, reliable alerting solutions are needed. That's the AlertNow™ network.
AlertNow harnesses SpectraRep's proven datacasting technology to deliver critical alerts through TV broadcast signals that have served communities reliably for decades. By creating an independent pathway for emergency messages, AlertNow ensures warnings reach their destination, whether communities face approaching wildfires, tornado threats, or hurricane evacuations.
AlertNow keeps vital information flowing to both first responders and residents, providing an essential lifeline during disasters.
The U.S. has a diverse television network spanning 210 markets nationwide, with a mix of commercial and public TV stations. AlertNow systems and broadcasting equipment have been installed at more than 250 locations, including 130 main stations and 120 relay stations nationwide.
The AlertNow network currently reaches over 220 million people in the United States, delivering all-hazards alerting capabilities to both emergency management personnel and the general public.
