Show Notes
What happens when a tornado hits and the cell network is already jammed with panicked calls? How does your phone scream a warning even if you have no service, no SIM card, or a dead battery? We are peeling back the layers on Cell Broadcast, the "one-to-many" radio protocol that sits silently in your phone's control channel. We explore why it’s not a text message, how it uses the FM radio part of the network, and the geo-fencing magic of WEA 3.0 that knows exactly which side of the street you're on. It's the invisible infrastructure that keeps you alive when the grid fails.
