Low power wireless network
LoRaWANâ„¢ is a low power wireless network protocol that makes use a very efficient chirp modulation scheme.
Compared to other wireless technologies, LoRaWANâ„¢ provides a much higher coverage range,
a more robust error tolerance and smallest power consuption by the price of a quite limited bandwith.

Low frequencies - better pervasion
Depending on the region LoRaWAN uses frequencies around 800-950Mhz (868MHz in Europe, 915 un the U.S.) which is
a frequency band much less attenuated and reflected by obejcts like walls. This and the variable redundancy gives
LoRaWANâ„¢ an advantage of 100 to 1000 in terms of bidgable distance.
