6% of TV stations are operating in Puerto Rico
15% of radio stations are operating in Puerto Rico
Nationally, there are about 28,000 cable systems, radio and television
stations.
This test will not use the FEMA primary entry point system, so its only a
partial test of the national EAS.
Today's national test of the Emergency Alert System will be the same as
the 2016 national test. It is a partial test of the EAS, using the FEMA
IPAWS system over the internet (i.e. Akamai and Cloudfront are used as
CDNs) to the distribute the emergency test message. Cable, radio and TV
stations need a working Internet connection as well as radio receivers and
transmitters for IPAWS and EAS.
Although the national test was scheduled back in July, its still a good
test opportunity to see how the internet and EAS works in Puerto Rico and
the U.S. VI with so much damage to the infrastructure. The one minute
national test should not intefere with disaster recovery efforts in PR or
USVI.
