First off - loved hunt the wumpus when I was little.
Second, I'd consider what's possible as well - as in mesh network solutions that would apply to a community.
You can get over a gig with a 24ghz point to point for around 50W max draw. For point to multi, you can do something like the prism station for only 10W or a simple AP for less noisy environments. You can then extend with mesh for another 10W max or so.
Its perfectly viable imo to get 100mbit or more on pretty low power. You could get more than 24hrs of backup off a wheelchair battery for even the point to point stuff which will require more power for the long distance transmission.
With a bit more money into equipment, speeds can go even higher, but even at the lower price point you can get quite a bit more than 10mbit with large scale mesh. More than enough for most use cases!
