SaiaNet seems to be good fit for various public safety entities. AMR, Mercy Flight, E. Aurora, Lackawanna, W. Seneca, Lancaster, etc. They offer multiple talk-groups, dedicated Emergency channel, tracking, wide-area coverage, complete interoperability with outside agencies, integrated console solution, fault tolerant infrastructure, all the things Public Safety wants, but is very expensive to design, install, and maintain. It is simple to see that private can fill and maintain these systems, better, more cost effective, than the Public Safety entities can themselves.
Tonawanda, Kenmore, N. Ton, all with Kenwood 5300 series radios will work natively, seamlessly, on a soon to be offered DMR III system. This will offer complete Public Safety interoperability, including priority pre-emption. New Generation radios also offer Cellular integration, effectively allowing National Coverage. P25 is pushed by lobbyists, not because it's better, but because it puts a lock on agencies, and forces end users down an expensive path, making hundreds of millions for the lobbyists. If public monies were not handed out to buy P25 (Note: Many buy the P25 radios, but run them in other formats, mostly analog), the majority of the country would be buying lower tier radios, and be very happy with them.
Just an opinion ....
