Note this system appears to be in the process of being replaced; see PACMERS 2CF for the new system.

 "The Pacific Mobile Emergency Radio System (PACMERS) is the program directed by the United States Pacific Command (USPACOM) that establishes a Land Mobile Radio (LMR) system in Hawaii. PACMERS is a system borne out of a requirement to save lives. This system allows emergency medical service providers, fire and police to communicate using interoperable radios. During accidents and disasters emergency personnel in Hawaii will need enhanced interoperable communications in order to provide a rapid response."

"The PACMERS wide-area trunking system is a fully integrated interoperable radio system that meets the National Telecommunications Information Agency (NTIA) mandate for narrow band operation for military/federal agencies. PACMERS also provides a Project 25 Standard for Voice and Data Interoperable Radio Communication solution for migrating federal, state and local government agencies which allows systems to interoperate, regardless of manufacturer."

"The PACMERS LMR system has been in operation in Hawaii since October 10, 2002. There are currently 2629 radio users on the network, representing the Army, Air Force, Navy, Marine Corps, National Guard and other government units. PACMERS began with four RF sites on Oahu and one on the Island of Hawaii. In early 2005 two new Oahu sites were added and more sites are planned for the future on the Big Island of Hawaii."
