LoRawan defines the communication protocol and system architecture, while LoRa defines the physical layer. LoRaWAN uses a remote star architecture. Wherein the gateway is used to relay messages between the terminal devices and the central core network. In a LoRaWAN network, nodes are not associated with a particular gateway. Instead, data sent by a node is typically received by multiple gateways. Each gateway forwards the received data packets from the end node to the cloud-based network server over some backhaul (cellular, ethernet, satellite or Wi-Fi). The end devices (i.e. sensors and applications) communicate with one or more gateways through single hop LoRa communication, while all gateways are connected to the core network server through standard IP connections.
