Thus, the LoRa network can be easily deployed over several kilometers and serve customers with minimal investment and maintenance costs. 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. The web server has the intelligence required to filter duplicate packets from different gateways, check security, send ACKs to the gateways, and send the packets to a particular application server. Since the network can select the best quality information among the information transmitted by the different gateways, no handover is required. If the node is mobile, no handover is required from gateway to gateway, which is a key feature of enabling asset tracking applications, which are the main target application of the vertical internet of things. By using a mesh network, the system can increase the communication range of the network at the expense of device battery life.
