4-hop route
A remote device sends a unicast transmission to a concentrator that is 4-hops away. The concentrator
emits a route record that can be stored for use in a
prior to sending data back to the remote.
The route looks like this:
Destination (concentrator) <> Router A <> Router B <> Router C <> Source (remote)
