How much longer do you think COIRS will exist? I figured MARCS woudl have swallowed them up by now just like most of the other alternative radio systems in Ohio.
I don't figure they're ever going to go away. In my opinion it's primarily based on a question of system governance; COIRS is governed by a Council of Governments (COG) in which each stakeholder (Delaware County, Upper Arlington, Norwich Twp/Hilliard, Washington Twp/Dublin, Worthington) has an equal vote in the operation of the system. MARCS is governed by a steering committee made up of state agency representatives.
As long as I can remember, Franklin, Delaware and Pickaway counties have had a pretty strong sense of maintaining local control; several other areas in the state with their own systems are much the same. When everybody in Franklin County was joining the City of Columbus and Franklin County systems in the pre-P25 days, there were some pretty pointed discussions about how to configure COCAC (Central Ohio Communications Advisory Committee) so that everybody would have a voice in system governance, but it got done and has worked pretty well. COCAC carried over to the process of joining MARCS as Tier 4 partners.
And to be fair, there is a Local Government representative on the MARCS Steering Committee now, and over time I think the Steering Committee will become more representative of the overall user base. And MARCS does listen and respond to user concerns.
As for COIRS, there is a really strong sense of individuality there and I don't think they'll ever give up their own system; the most I would expect to see would be limited connectivity via ISSI for interoperability.
Just my opinion.....
(PS being an old Liberty Township guy, you might be interested to know that they're running automatic response with Columbus FD quite a bit these days....)
