[DisasterRadio] GPS Maps, Chat, Mesh - thats AX.25 & APRS, no?

[Dean H (KC4KSU)]

There is definitely an overlap of functionality between APRS and DR’s goals.  The reason APRS works is because of the large volunteer army of hams.  I wouldn’t say APRS does “mesh”, but with the right path settings it does multihop to get to an igate and on to the internet.  APRS has a significant RF and internet infrastructure.  I would hope DR could be lighter weight than that.

I think that since DR's application layer is using TCP/IP, the NET and Link layers could be more akin to 6LoWPAN <https://en.wikipedia.org/wiki/6LoWPAN> and meshing via RPL <https://en.wikipedia.org/wiki/RPL_(IPv6_Routing_Protocol_for_LLNs)>.  Projects like RiotOS <https://www.riot-os.org/> or Thread <https://github.com/openthread/openthread> might provide a foundation.

But I kept thinking about an APRS node I made w a baofeng and an RPi3.  And how all of this was basically another way of doing what the APRS net and  AX.25 already do in the amateur radio slice of things.
