LoRa blocks
LoRaWAN is a media access control layer protocol for managing communication between LPWAN (Low-Power Wide-Area Network) gateways and end-node devices, maintained by the LoRa Alliance. Version 1.0 of the LoRaWAN specification was released in June 2015.
LoRaWAN defines the communication protocol and system architecture for the network while the LoRa physical layer enables the long-range communication link. LoRaWAN is also responsible managing the communication frequencies, data rate, and power for all devices. Devices in the network are asynchronous and transmit when they have data available to send. Data transmitted by an end-node device is received by multiple gateways, which forward the data packets to a centralized network server. The network server filters duplicate packets, performs security checks, and manages the network. Data is then forwarded to application servers.
