Information on FirstNet the new Federally funded digital network for first responders is starting to become more available. While the funding is "top down" there is a great deal of work to be done by each state to position themselves to participate.
I had the opportunity to do a Disaster Zone TV show with Bill Schrier, Washington State's point of contact for the implementation of FirstNet. While the discussions center on what is being done here in the Pacific Northwest much of the information is applicable to other states. If you don't know anything about what is being proposed this is a good place to start. And, there is information here that you won't find in any printed fact sheet on the program.
