TTN (The Things Network) has announced the LoRaWAN technology by offering a free LoRaWAN network server that is accessible to everyone. The principle is to build an open LoRaWAN network with international coverage. It is a community where all members agree that their own infrastructure (LoRaWAN gateways) can be used by everyone. It is a free service provided that all data from all available sensors in the vicinity can use your gateways to communicate with third-party applications. There is no guarantee for the availability of different nodes of the network, except for the LoRaWAN gateways that you add yourself. Thingsdata offers standard integration with The Things Network.
