The Things Network Stack for LoRaWAN is an open source LoRaWAN network stack suitable for large, global and geo-distributed public and private networks as well as smaller networks. The architecture follows the LoRaWAN Network Reference Model for standards compliancy and interoperability. This project is actively maintained by The Things Industries. LoRaWAN is a protocol for low-power wide area networks. It allows for large scale Internet of Things deployments where low-powered devices efficiently communicate with Internet-connected applications over long range wireless connections.
