How does the Emergency Alert System (EAS) differ from the Wireless Emergency Alerts (WEA) system in terms of communication channels?
EAS broadcasts alerts via cable, satellite, and traditional radio and TV, while WEA sends alerts directly to mobile phones.
EAS sends alerts only to mobile phones, whereas WEA uses radio and television broadcasts.
EAS and WEA are the same system and use identical communication channels for alerts.
