 It's been on my mind recently with the two hurricanes that just hit the southeast United States back to back and did lots of damage, especially in North Carolina. I've also been an amateur radio operator for several years and this just looks like a more modern version of amateur radio. If I'm understanding correctly, this thing has a 3-hop maximum, and that sounds very similar to APRS on 2 meters 144.390mhz.

 3 hops is default, but it can be moved up to 7 I believe. 

This is with the default 3.

 Okay, so the receiver point and the final broadcast point in this picture do not show numbers where I believe APRS on amateur radio. The first node that receives it automatically decrements it to the number two before sending it on. So it would not go as far, at least if I understand correctly.
