It is cool! The barrier to entry is relatively low. The only thing to really worry about is:

  1. What band/frequency is appropriate for you country.
  2. Are there others around to which you can connect?

If there’s not a lot of people around it’s not the end of the world. Nodes can connect over the Internet via MQTT servers. Yes, this defeats the purpose of having an offline/decentralized communication platform, but it is a good stop gap until more nodes are put up.

Here’s a sample of what I can see in a somewhat large-ish Midwest City in the US (there’s about 63 nodes I can reach by hopping through relays).
