Emergency Radio System

About the measures

The Allied Radio Matrix for Emergency Response (ARMER) is a statewide emergency radio system. ARMER was first built in the Twin Cities in 2001, then moved to St. Cloud and Rochester, and has expanded throughout the rest of the state. MnDOT measures the percentage of the ARMER buildout completed.

Recent trends

As of 2019, ARMER build out reached 100 percent. Over 94,000 radios registered and over 79,000 radios are active. ARMER build out is complete. The emphasis is now on transitioning from buildout to maintenance and improvements.

Where we want to go

MnDOT continues to operate and provide routine maintenance to ARMER including monthly reports, FCC licensing, and system improvements. ARMER is currently version 7.15 and is in a five-year transition period to version 7.19.
