At 2:18 PM and Wednesday, most of the phones exploded with a surprisingly loud sound and a message saying, "THIS IS A TEST of the National Wireless Emergency Alert System. No action is necessary. "
Some people did not do it. And the government does not know exactly why.
Obviously, some phones have been turned off or out of reach of mobile phones. And if you were in the middle of a long phone conversation, it would probably have spared you the alert. But even then, many people offering good service, sitting next to people whose phones have been alerted, have never had it.
The alert was broadcast for 30 minutes and, according to FEMA (Federal Emergency Management Agency), which sent the test, it should have gone to "compatible mobile phones turned on, within reach of an active cell tower provider participating in WEA should be able to receive the test message. "
There does not seem to be a common link between those who received the text and those who did not receive it. Some Android users did not understand it, others. Some people with AT & T say they have not received the message. But some did it. The story is the same with Sprint and Verizon.
Here are some of the reasons why FEMA is interested in explaining this gap:
- The firmware of the new phones reacted unexpectedly with the system of alert
- Latency issues with radio access nodes
- Protocols used by cell phone companies
FEMA plans to report on the successes and failures of the test in the coming months. In the meantime, he is asking the public to send his comments to [email protected].
If you have not received the alert, the agency asks you to include information about the device that you are using, your mobile phone provider, if you were using their phone when the phone number was higher. 39; alert has been issued and if people nearby have received it.
