Another way of looking at the IoT structure here may help put this ecosystem in prospective. The edge nodes may have a connectivity component that usually connects the end device to the gateway, and must have some sort of sensor depending on the application and embedded processing to process this information. The edge node data is then passed from the gateways to the network. This core network could be cellular, ethernet or others. The function for this core network is to deliver this data next to an operation management median that delivers the data ultimately to an IoT cloud service.
