Everyone who thinks that the FDNY (or any other agency in NYC) is going to go high-tech with their radio systems are forgetting one, big important thing: NYC is BROKE.
They already did, FDNY spent 89 Million 12 years ago to replace all the portables with APX8000s and mobiles.
NYPD has spent over 200 Million for radios and infrastructure upgrades and is now Moving to all P25 encrypted comms
DOITT or whatever they are called now has spent over 300 million upgrading the 2 Trunk systems to P25, adding sites, buying mobiles and portables, building out mesh networks, and on and on
So NYC is very high tech and they are now buying APX-Next radios so they can use them on RF & other networks
Just a different budget or line item or whatever they do to make it happen. Public safety and public services in any big city are always broke
