Multi-Agency Radio Communication System

MARCS Mission

MARCS (Multi-Agency Radio Communication System) is dedicated to providing Ohio's first responders and public safety providers with state-of-the-art wireless digital communications, and to promote interoperability, in order to save lives and maximize effectiveness in both normal operations and emergency situations.

MARCS Facts

MARCS is a 700/800 MHz radio and data network that utilizes state-of-the art trunked technology to provide statewide interoperability in digital clarity to its subscribers throughout Ohio and a 10 mile radius outside of Ohio.  The MARCS system provides statewide, secure, reliable public service wireless communication for public safety and first responders.

The MARCS development contract required 97.5% mobile voice and data in street coverage.  99.71% aggregate voice coverage was realized and 98.13% aggregate data coverage was achieved.  This allows maximum statewide interoperability and enhanced safety and protection for public safety service providers through secure digital transmissions.

The MARCS network operates on three system components:

  • Mobile Voice - operating on the 700/800 MHz digital trunked technology
  • Computer Aided Dispatch (CAD) - providing GPS-based vehicle location, resource recommendation and GGM display
  • Mobile Data - CAD updates, Records Management, GPS-Based vehicle location, LEADS inquiries

There are currently over 140,000 voice units and over 1,800 mobile data units on the MARCS system with more than 3,000 public safety/public service agencies statewide.  This includes local, state and federal agencies.

Information and Resources

Tower on Wheels

MARCS has three (3) Tower on Wheels (TOWs) that can be requested for incidents within Ohio requiring interoperable communications.  The TOWs are used to supplement coverage and/or to add capacity to an area where an emergency or event is occurring.  The MARCS TOWs are deployed to your request by MARCS staff and are self-sufficient for 48 to 72 hours.

Included in the deployment is at least two members of the MARCS staff, a towing vehicle, 109 gallons of diesel fuel, and related equipment including the TOW itself.  The TOW includes an 80 foot tower, grounding, 20KW three phase diesel generator, electrical cables for direct wiring, cache radios, extra radio batteries, and bank chargers. MARCS also has a towable generator that is normally dispatched as a backup for the generator on the TOW.  Once the TOW arrives on your incident, usually within 30 minutes to one hour the TOW is operational and ready for use.  The TOWs are deployed on a first come first served basis.  The TOWs can be used for large events, exercises, or any emergency situation.  A TOW can be requested by calling the MARCS Helpdesk 24/7 at 866-646-2727.

Demonstrations are also welcomed.  Any questions or concerns can be directed to Dick Miller at dick.miller@das.ohio.gov, Field Operations Manager for MARCS.
