Point well taken, and my apologies for airing dirty laundry. Thank you, however, for adding the citation to your site.
In short, GEWIN (Georgia Emergency Wireless Interoperability Network) is poised to be a pure P25 statewide interoperability radio system. Right now, there are a couple of networked simulcast sites: One in Atlanta, and another in Cobb County. Cobb County is the only municipality using the system full time. All, or most all, of Cobb County police has migrated to the system, and much of the rest of Cobb County's and many Cobb municipalities' agencies intend to migrate to the system.
What I've been told, however, is that the system isn't actually intended for everyone to hop on board and use it as their primary radio system. It really is more for interoperability when agencies need to talk to one another, not when they need to talk amongst themselves. Cobb is the guinea pig, which is why they are fully migrating to the system. I'm not sure what to make of this supposition, however. I personally think that if you're going to invest in a statewide system, then use the darn thing to it's fullest potential.
My role is simple...Here's the article that explains it all:
