Emergency Communication Networks

A Division of the Minnesota Department of Public Safety


ARMER was first built in the Twin Cities in 2004, then moved to St. Cloud and Rochester, and has since migrated throughout the rest of Minnesota. ARMER currently serves as the primary communications tool for the majority of state, county and local public safety entities in Minnesota. 
The Minnesota Department of Transportation owns the core infrastructure providing the ARMER backbone and 95-percent mobile coverage.  Many local units of government own local enhancements providing improved local and in-building coverage. 
For the more technically minded:
  • ARMER is a P25, Motorola, SmartZone, 800 MHz, phase 1, trunked radio system utilizing six zone controllers.
  • ARMER is currently version 7.15 and is in a five-year transition period to version 7.19. 
  • ARMER possesses over 7,200 assigned and over 6,200 active talkgroups. 
  • Over 96,000 radios are registered and over 81,000 radios are active. 
ARMER is now essentially complete. The emphasis now is on transitioning from buildout to maintenance and improvements.
