LPWAN
Overview
Create a low power widely distributed network to support sensors in remote areas. Sensors might include rain gauges (low data) or critter cams (high data).
Once the network is in place we can find other applications, for example it could be used for text messaging when in the field. It could be used to track critters wearing rf collars .. if the WAN is big enough might not need any GPS / data logger to support this, just a transponder.

AX25, RadioHead compiled under Atmel studio 7; I stripped out both the 'GPS' in the AX25 dir,
and everything in RadioHead but the 'RHSerial' driver ...
now, gotta ponder how best to bolt up the init() and loop() functions in AX25.cpp with that Serial driver... and utilities to store one's call sign, etc in EEPROM, etc ..
also, this is kinda interesting... http://forum.arduino.cc/index.php?topic=240624.0
came across this too... getting the whole Bertos code to compile is a pain... http://slepp.ca/projects/ax25-modem/
The RadioHead stuff does indeed just drop into an Arduino sketch, and looks very active from their mailing list ...
speaking of NiceRF, this look extremely interesting too (!) and all "spelled out" on Arduino .. that would eliminate all A/D and codec, although it wouldn't have 5W of power from a handset... but a whole lot cheaper!

supposedly this library works on it too: http://www.airspayce.com/mikem/arduino/RadioHead/
"..RH_RF95 Works with Semtech SX1276/77/78/79, Modtronix inAir4 and inAir9, and HopeRF RFM95/96/97/98 and other similar LoRa capable radios. Supports Long Range (LoRa) with spread spectrum frequency hopping, large payloads etc"
Going to try to download, compile Radiohead now...
