Standardized by the LoRa Alliance, the LoRaWAN specification allows low bit rate communication between connected objects in a wide area network (WAN).
Long Range Wide Area Network (LoRaWAN) is a low power wireless networking protocol designed for low-cost secure two-way communication in the IoT. LoRaWANs use of sub-GHz ISM bands also means the network can penetrate the core of large structures and subsurface deployments within a range of 2km. The technology utilized in a LoRaWAN network is designed to connect low-cost, battery-operated sensors over long distances in harsh environments that were previously too challenging or cost prohibitive to connect. With its unique penetration capability, a LoRa gateway deployed on a building or tower can connect to sensors more than 10 miles away or to water meters deployed underground or in basements.
