IPAWS-NOAA Gateway: This is used to deliver alerts to weather radios.
Government officials estimated that the alert would reach upwards of 225 million USA cellphones or around 75 percent of all phones. This will be a test of the country's wireless emergency alerting system. "No action is needed", it'll read.
FEMA estimates some 225 million devices, or about 75 percent of cellphone users in the US, will receive the alert. This is just a test, and it has been planned for some time.
The system test is for a high-level "presidential" alert that would be used only in a nationwide emergency.
Though this is the fourth nationwide test of the EAS, Wednesday marks the first time the federal government has ever tested out the WEA on a national level.
With the IPAWS system, messages from local officials during an emergency will go out to the public on smart devices in a single alert.

"FEMA and the nation's emergency management community remain committed to the life-saving activities occuring through parts of North Carolina and SC", a FEMA spokesperson explained. Of course, you're cutting off all communication for your phone so you won't get any calls or other messages.
All WEA alerts are given to FEMA by the president.
If you get an emergency alert on your phone Wednesday afternoon, don't be alarmed.
It will come through a system already integrated in Hamilton County.
"We're not going to put it out there unless it's an emergency, unless it's vitally important that someone see that information and maybe they can make a difference in protecting themselves or rescue somebody else", Dwight said.
"Whether it's a natural disaster or an act of terrorism or a man-made event that could affect the general public in Hamilton County", she said.
The WEA is only for cellphones which are capable of receiving the texts, within range of a cellphone tower, and are using a provider included in the test.
The system is run by the Federal Emergency Management Agency, which says all of the country's major cellphone carriers participate. You'll hear two tones, followed by a vibration. It's also possible that if you leave your phone off or have a call that lasts for more than 30 minutes, you might not receive the alert at all.
