To this day, I can still drive less than an hour out of a major city, lose cell service and let my finger wander to the site button on my radio only to see a 100+ RSSI level display.

LMR is going to IP base and for the most part, all digital capable equipment in current production supports IPv4 at a minimum. Away with the channel banks and having the ability to phase T1/T3's out for more direct IP based mediums.

Adapt to further enhance the quality of communications. That's where the industry is going.
I see DMR and IP site connect as positive evidence of LMR/IP convergence. One thing to remember is that those T1/T3's had "5 nines" of design target for redundancy, while IP has always been "best effort".
