From the Update Overview: "The National Emergency Communications Plan (NECP) is the Nation's strategic plan to strengthen and enhance emergency communications capabilities. The Cybersecurity and Infrastructure Security Agency (CISA) worked with over 3,500 Federal, state, local, tribal and territorial public safety agencies and organizations to develop the NECP. As a result, the updated NECP addresses the current gaps within emergency communications and promotes the innovation and integration of new technologies, while considering their associated risks. In addition, it provides guidance to drive the enhancements of the Nation's emergency communications capabilities."
