LoRaWAN

 
 
LoRaWAN (Long Range Wide Area Network) is a specification for a telecommunication network suitable for long-distance communication with little power. The technology is used for machine-to-machine communication (Internet of Things).

The architecture consists of gateways, network servers and application servers. There are RF chips from Semtech used to transmit a spread spectrum.
