Bill,
Here is an unrestricted older briefing on FirstNet: http://telecom-digest.org/FirstNet/FirstNet_overview.pptx
Also interesting when State of Florida rebid their Public Safety radio network they required the radios to be LTE interoperable. In the
event of a hurricane that takes out their P25 infrastructure, or a
massive local need that exceeds bandwidth, they can switch radios over
to LTE (presumingly FirstNet)
Having said that you don't see a lot of "walkie talkie" users on first
net. It's mostly cell phones, tablets, Mobile routers, EKGs, MDTs,
Liscense Plate readers, etc.
FAA has put a few weather sensors on FirstNet (as TDM transport
becomes obsolete, and they don't need a 3 Mbps carrier Ethernet
circuit for ~200 bps of data).
There is an app called Tango Tango that simulcasts Land Mobile Radio
over LTE- basically allows public safety command staff and volunteer firefighter to monitor a frequency without having to lug a radio
with them. They obviously advertise it's not safety critical, the
idea is when they respond they will switch over to a standard radio,
but they can maintain situational awareness or be contacted through
the app. I've played with it - and it appears to work well in either
use.

Kudos to Florida: I just hope that the hurricane/flood/whatever
doesn't take down the FirstNet sites at the same time it's destroying ordinary cell towers.

Whoa! Have mercy! I'm an analog tech in a digital world!
What are "EKGs?" What are "MDTs?"

At that rate, the Morse keys and sounders in the Gamewell boxes might still come in handy! ;-)
