So we are grant dependent. See this website that lists many that you are aware of already — if you are chasing money like I do: How to fund FirstNet implementation in your agency.
Don't let the title above fool you — this is not just about FirstNet, but it is an element that can be included in the funding, if you make that choice.
There are other grants sources that you may not be familiar with and could explore. I also think that community foundations are another source that we typically are not examining.
Until there is another national calamity, we can only expect available grant funds to continue to decrease. Learn to live with less or go find new sources of funding.
