Great!! I am getting it!
Just a curiosity.. About the network in Amsterdam, who pays for the gateways internet access? Is the TTN company? The city?
Another question. Let's suppose I have a node that is travelling fast (inside a drone for example). Imagine this node send a message to one gateway. The packet goes all the way to the app and comes back to the gateway that sent the packet in the first place.. but now the node is not within that gateway radius anymore, It is now within another gateway coverage. In that case is impossible for the node to receive the feedback signal? Or is there some way the node can tell the gateway something like "send the feedback message to the next gateway"? Or can the node, when within the coverage of the next gateway, send a message like "you, new gateway, feedback the message to me"?
I don't know, just thinking about the possibilities. I am currently working with drones and I thought about this network as a good air traffic management!
