Gwinnett PD Goin' Digital

[N8IAA]

Is the Gwinnett P25 system part of what's being called GEWIN? Or is GEWIN just Cobb County? I ask because Atlanta and DeKalb are supposed to migrate to P25. And as I understand the whole point of spending tens of millions of dollars is so that people can talk to one another.
Same for Forsyth County...is this part of GEWIN?
So, if a Cobb County officer is in hot pursuit of a person who just shot five people, goes through Atlanta, then north on I-85 into Gwinnett then into Forsyth or Hall, will their radio work seamlessly? Or is the officer SOL?
I would think the P25 systems being built are all linked together somehow. Or is that another 50-million?
Please tell me GEWIN is not just Cobb County!

From what I got from a talk with a Gwinnett FF, that they can on their new radios talk to DeKalb(which didn't work on a recent fire they did mutual aid on). I was monitoring GCFD when getting that info. Forsyth, Gwinnett, DeKalb, and Atlanta are not a part of GEWIN. Hall has their own system, also.
So----SOL it is. Unless they can hook up by talking back and forth between the separate dispatchers. But, wait a minute, isn't that what interoperability was supposed to take care off?????????
