End-devices are simple objects such as sensors, actuators, and are the “things” in the Internet of Things. An end-device communicates to the network server through one or more gateways. The gateway acts as a concentrator for the end-devices and relays the data between end-devices and the network server. The wireless connection between an end-device and the gateway is set up through a LoRa® wireless link. The gateways, network server, and application servers communicate over an IP backhaul linked using Ethernet, 3G, LTE, and so on.
