Working Principle
CMAS works by using a technology called Cell Broadcast, which transmits messages to all cell phones within the target area simultaneously. When a CMAS message is sent out, it is broadcast to all compatible devices that are on the same network with a certain geographic location within that defined by the U.S National Weather Service (NWS). No action is required from the user for a device to receive the message since Cell Broadcast does not use SMS messaging or require users to make any special configuration settings on their device. The message will be received regardless of whether or not their phone is active at that particular moment in time.
Benefits
The biggest advantage of CMAS is its speed; officials can quickly spread warnings and notifications across large populations in areas affected by emergencies and outbreaks in no time. These notifications can also reach people who might be off-grid since CMAS does not require users to have access to internet data or a Wi-Fi connection - as long as they are within range of an area with wireless coverage, they will receive these timely updates without fail. Additionally, this system eliminates language barriers since it broadcasts messages using both text-to-speech audio and visual displays that make it easy for everyone to understand whatever message they may receive.
