MnDOT owns, builds, operates and maintains the ARMER backbone. ARMER is Minnesota’s shared public safety radio communication system.
The system backbone is a network of radio towers, equipment shelters and radio transmission equipment. This backbone is shared by network users throughout the state, as identified in the Statewide Radio Communication Plan maintained by the Statewide Radio Board.
The ARMER backbone is used by MnDOT, the State Patrol, the Department of Natural Resources, and other state agencies for voice and data communications. The backbone is shared with local governments and other emergency response organizations so that all emergency responders can have interoperable communications with each other.
