CAS - Concept

• The Community Alerting System (CAS)
• Broadcasts emergency warning messages via
  wireless networks using designated zones/cell
  sites, while enhancing Emergency Operations
  Center (EOC) effectiveness without increasing EOC
  responsibility or impacting the wireless
  infrastructure.

CAS System Flow

• The typical CAS System Flow
• The EOC is notified by appropriate authority.
• The proper warning level is determined by the
  city/county EOC.
• The areas in immediate danger are located using a
  standard mapping software.
• Wireless zones in threatened area are selected by
  the EOC.
• Emergency warning triggers are sent to specific
  wireless switches which send commands to cell
  sites in the designated zone.
• Warning messages are received by all
  fixed/mounted and mobile receivers.
