[aprssig] LoRa GPS tracking

I've done some experimenting with a GPS tracker (Dragino LGT-92)
fitted with an external mag-mount antenna. While this operates
in the 902-928MHz band, it falls under Part 15 unlicensed operation.
Transmit power on the LGT-92 is +20dBm (100mW).

In several test drives, I've found excellent coverage via Helium hotspots.
Yes, Helium costs money ($1 for 100,000 packets) but the infrastructure
is pretty amazing.

I appreciate the change here from licensed amateur radio operation
to unlicensed operation - but consider this makes it available to all.
With a bit of planning, this easily permits global coverage.

I also appreciate the LoRa radios are Semtech proprietary IP. They're cheap
enough and widely available.

LoRaWAN uses AES-128 encryption from edge devices, so there's
little eavesdropping that can be done. Note that encryption is not
an issue for Part 15 operation.

Has anyone proposed/implemented APRS functionality on LoRaWAN?
