I can't explain much about what's available but you need to remember that ham radio cannot be used in furtherance of business. Thus things like connecting to the internet via ham radio contain significant legal perils for the ops.

My employer floated the idea of listing all the hams who might like to volunteer to help during a major emergency. No problem, folks identified themselves as hams.
When "business continuance in case of emergency" became part of the discussion the hams noted their regulatory prohibition against helping in that way. And the whole idea went dormant - as it should.

If you were pursuing "business continuance" for your employer you'd encounter similar issues.

If you were pursuing backup comms for the fire dept the barriers should be fewer since that would clearly be in the public interest.
