Inside MPSCS


Beginning in mid-1990, the State of Michigan made a significant investment in its infrastructure that provides statewide radio communication for first responders. While Michigan’s Public Safety Communications System (MPSCS) was first implemented to serve the Michigan State Police, that scope expanded. In recent years, the Departments of Natural Resources and Transportation also have become reliant on the system.

MPSCS provides a stable, secure framework for interoperable communications among local, state, federal, tribal and private first responders. This standards-based public safety communication system supports first responders in their service to citizens. Through its employees, MPSCS handles the second-largest trunked communication system in the world, including administration of a statewide 800/700 MHz digital trunked radio communication network. As of January 2023, the system spans from the shores of Lake Superior to the borders of Ohio and Indiana, has over 300 radio towers and includes more than 146,000 radios.

The system is at the forefront of public safety communications. It provides rapid response and facilitates cooperation of emergency personnel through statewide coverage and advanced technology. It is a reliable, easy-to-use system that adheres to national standards. System operation is monitored 24 hours a day to ensure its readiness to assist Michigan’s first responders.

No single emergency communications system – no matter how large or how powerful – can meet its communications challenges alone. The Office of Michigan’s Public Safety Communications System (MPSCS) partners with local, state, federal, tribal, and private first responders in all eighty-three counties to provide the statewide public safety communications solution, a resource aiding the response to the residents of Michigan.
