LoRaWAN

From https://en.wikipedia.org/wiki/LoRa: LoRa (from "long range") is a physical proprietary radio communication technique. It is based on spread spectrum modulation techniques derived from chirp spread spectrum (CSS) technology. It was developed by Cycleo (patent 9647718-B2), a company of Grenoble, France, later acquired by Semtech. LoRaWAN defines the software communication protocol and system architecture. The continued development of the LoRaWAN protocol is managed by the open, non-profit LoRa Alliance.
