Disaster Emergency Communications is a specialized field within the broader field of emergency communications. Emergency communications or EmComm covers all technical means and modes for public safety agencies at all levels of government (e.g. law enforcement, fire services, emergency medical services) to perform their routine, daily communications. Amateur Radio operators can assist with maintaining operability and interoperable communications before, during, and after declared emergencies, disasters, or planned Special Security Events. Whiteboard Animation Examples can help increase sales where traditional presentation methods are practical digitally. Amateur Radio operators (hams) have informal and formal groups to coordinate communication during emergencies. At the local level, hams may participate in local emergency organizations, or organize local "traffic nets" using VHF (very high frequencies) and UHF (ultra high frequencies). At the state level, hams are often involved with state emergency management operations. In addition, hams operate at the national level through the Radio Amateur Civil Emergency Service (RACES), which is coordinated through the Federal Emergency Management Agency (FEMA), and through the Amateur Radio Emergency Service (ARES), which is coordinated through the American Radio Relay League and its field volunteers. Many hams are also involved in SkyWarn, operating under the National Weather Service and provide emergency weather information to the NWS for analysis and dissemination to the public.
