Again, good points.

We are looking at the Harris radios with the WiFi as a way to address in building coverage. It's way easier for us to get funding to deploy more WiFI WAP's than it is to get money for public safety. Everyone wants more robust internet access, and they'll scream if they don't get it. Ask for money for a public safety radio system, and they'll ask "why?".

AT&T has already announced that they're going to be shutting down conditioned circuits for radio systems around 2020, and we'd better start looking for a solution. That solution -will- be IP.

The trouble we are running into with IP is that most network guys don't have a clue how public safety radio systems work. Where I work they are willing to provide bandwidth for our needs, but getting them to give us a high QOS isn't something they are eager to do. Add in the requirements for uptime (Five 9's) and they get really nervous.
Part of my job includes running the PBX, and we went VoIP back in 2008 for the backbone. That laid the groundwork to get the network core to 99.999% uptime, router pairs at each site, DC power plants, etc. It's worked well, and we'll make it work for radio, but there's still the average IT guy learning curve. Getting that level of service out to the network edge is an entirely different story. We still won't deploy VoIP phones at critical locations.
