Yesterday Johan announced The Things Network's new open source LoRaWAN network server.
"The last years of being at the center of LoRaWAN activity globally we gained a large amount of knowledge on how to operate LoRaWAN. Our new network server allows to be deployed in a wide range of deployment configurations. Ranging from building private closed networks with a backend on a Raspberry Pi to operating a global LoRaWAN internet service provider. It is compliant with the latest LoRaWAN 1.1 standard and has a wide range of scalability and end to end security features that allow you to get full control of the security and reliability of your sensor network. All with opt-in to the global collaborative LoRaWAN network of The Things Network."
