How does the CMAS system know what mobile handsets are in the alerting target area?

Does passive monitoring create a negative affect on the carriers' network?

No, Passive Monitoring by the CMAS system has no negative effects on the wireless carriers' networks.


Is mobile subscribers' privacy protected?

Yes, the CMAS system only collects the mobile handset number and the unique tower ID that the handset is currently operating on. The CMAS system has zero information about the alerting recipient, such as name or billing address.


Does the mobile user have to do anything to receive the alert?

Absolutely nothing; CMAS works with every type of handset in the market place and nothing is required of the individual prior to, or during the alert delivery.


When you say every mobile handset receives the alert, what about foreign visitors such as tourist or business travelers?

The system delivers the message to ALL handsets operating in the alerting target area. In fact, the CMAS system has the capability of recognizing a foreign number and actually delivering the alert in their native language.


What is meant by the term Persistent Alerting?

Persistent alerting is the CMAS system's capability of allowing the operator to choose a period of time that the alert will be in effect for the target area. This means that not only are all the mobile users in the target area immediately alerted, but any handsets that may travel into the target area during the prescribed time will also receive the alert.


What does multiple delivery methodologies mean?

CMAS utilizes the wireless carriers' present SMS system for primary delivery. For those handsets that are IP capable, the alert will be delivered over the IP network so as not to over burden the carrier network. As handset and network advances occur, the CMAS system will automatically shift more of the delivery process to the IP side of the network.


Why does CMAS employ message throttling?

The CMAS system works in concert with the wireless carriers' network capabilities and current traffic loads at the time of the alert. The throttling ensures that the CMAS system does not dominate the carrier network or over run its ability to deliver its present traffic demands.


What does CAP compliant mean?

CAP stands for Common Alerting Protocol, which is the global standard of a XML computer language for alert message dissemination.  The CMAS system is CAP compliant, which means it will interface with any existing EAS system that already may be in place.
