lora wan  - -long range wan by Semtech

low power 

1 msg every two minutes (2 secs to transmit a message, standard/legally specifies you should keep ther free for 99% of the time...)

TO VERIFY : 12 byte header - 50 byte payload
maximum packet length is 256 bytes (from Semtech FAQ)

encryption : 2 layers
MAC key
PAYLOAD key


868.1 
868.3 
868.5


semtech RF chips -- http://www.semtech.com/wireless-rf/lora.html
libellium has some fpga based 


high - low - high toggle on pin 12: start semtech transmitter
nwkskey : network key 'mac key'
