It works in Europe too. It uses LoRa (A Long Range radio protocol) to be able to send messages out to other nodes, which can bounce them out to further nodes. A node can be configured to relay through the Internet to reach people in other areas.
I ordered the radio shown below from a kit on Amazon (it’s a Heltec v4 and came with a battery that isn’t pictured) and it took about 5 minutes to setup. Attaching the antenna to the board was the hardest part.



Or else, what?
And I’m sure they will argue that since it says ‘shall’ and not ‘must’ then it’s just a suggestion.
