Hmmm, pricing is conspicuously missing. Let us know if you get the prices. I'm guessing $200 per node for the "private" and $1000 for the "public safety".
Then there will be the cost of the special ethernet boxes to drive them since they get power over ethernet.
And you will still have to hardwire powered ethernet cable to the nodes.
So, burried cable permits, lightning, safety, possibly FCC liscences?
This is not a cheap job.
