Your mobile phone will emit a special tone and vibrate as it receives an emergency test message on September 20. But it won't be a political message or attack on one of his perceived enemies-or at least, it's not supposed to be.
If you can't remember this happening before-you're correct.
UCLA communications professor Tim Groeling agreed, writing via email, "broadcast-based emergency alert systems. have remained professional and impartial over decades".
The administration will also send a test alert via radio and television broadcasters two minutes after the cell phone alert, part of a system long in use for alerts on severe weather and other emergencies.
You don't need to take any action for the test.
Users will have the option to opt out of receiving alerts for imminent threats and AMBER alert categories but will not be able to opt out of Presidential alerts.
This is the fourth EAS nationwide test and the first national WEA test, according to FEMA.
Mobile alerts sent through the WEA system are now categorized as imminent threats about emergencies in an area, including extreme weather, AMBER alerts for missing children or "Presidential alerts about emergencies of national effect", FEMA said.
FEMA said those whose cell phones are switched on, within range of an active cell tower, and whose wireless provider participates in WEA [Wireless Emergency Alerts] should receive the message only once.
The WEA system is already used to warn the public about missing children, unsafe weather and other vital information, FEMA said. The systems allows the president the "communications capability to address the nation during a national emergency".
Conducted minutes before a similar alert is slated to be broadcast on radio and television, the inaugural coast-to-coast test of the Wireless Emergency Alerts (WEA) system will gauge the readiness of the infrastructure needed for notifying the public of dire warnings, including specifically those issued directly from the White House, FEMA said Thursday.
In its news release, FEMA said it could postpone the national test to October 3 if the agency is dealing with a major weather event, but it have yet to make that determination.
