I will say this. AREDN, the Amateur Radio Emergency Data Network concept is something that needs to be considered.
And although this has been posted before, it's still relevant and would actually be something that would positively contribute.
If you can provide video feeds and date transfer from site to site YOu have something valuable.
Walking into an EOC on a small regional disaster and wanting to spin up HF radios and all that crap is pointless.
Who are you going to talk to that is 300 miles away that is going to assist the situation you are having right there? Answer is no one.
There is a time and a place for that level of communications, and you SHOULD be able to provide it when needed. But if that's all you bring to the table, then you serve no purpose typically.
Sure you can pass health and welfare traffic out for private citizens that they are OK to family members, but that's NOT EMCOMM. That's public service function, it doesn't fall under Homeland Security, EMA or ant other emergency service. It's a Red Cross function, not public safety.
Those folks don't give a rip if someones mother is informed 3 states away their son-in-law broke his leg but the family pet and everyone else in the house is OK. You need situational awareness. If you can bring in video and data.. That's usable stuff. How many people are in a certain shelter, the fact they are running low on toilet paper, or whatever, don't care. Bigger fish to fry. Pictures of damage in inaccessible area's, data connections between the EOC, police and fire dispatch, other EOC's in other neighboring counties. An IP phone system that operates across microwave that is not reliant on the telco's or cell towers, gonna say that might be useful as well.
Being able to talk to Florida when you are in Ohio. Not real useful in many situations.
