MARCS (Multi-Agency Radio Communication System) is an 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 800 MHZ digital trunked technology
• Mobile Data – allowing data transmissions, LEADS inquiries, reformatting of data from Mobile Data Terminals (MDT)
• Computer Aided Dispatch - providing GPS-based auto vehicle location, resource recommendation and GGM display 

There are currently over 23,000 voice units and over 1,700 mobile data units on the MARCS system with over 500 public safety/public service agencies statewide.  This includes local, state and federal agencies.
