From the Document: "To do their jobs effectively, public safety responders depend on sophisticated communications systems to relay mission-critical information in real time. Today's wireless communications systems must support an ever expanding set of missions, such as responses to domestic terrorism and weapons of mass destruction, requiring coordinated participation from agencies at all levels of government. Interoperability, or the ability for emergency responders to communicate among jurisdictions, disciplines, and levels of government, using a variety of frequency bands as needed and as authorized, is crucial to responders. The Statewide Interoperability Coordinator (SWIC) assists in facilitating communications among responders during emergencies and is an important asset when responding to planned and unplanned events." This document goes on to discuss SWIC's state level role, SWIC'S state level role in supporting governance, SWIC's national level role, supporting a full-time position in your state, and concludes with frequently asked questions.
