Den products use meshing to increase the coverage area. This means that not every device has to have a direct connection to the Hub.
You can increase the range of your network by using Den Socket Outlets. All devices need to be in range of either the Hub or a Den Socket Outlet.
Den products talk to each other using a custom wireless protocol built on IEEE 802.15.4. Your Hub connects to your home's Internet Router using a network cable and your phone communicates with the Hub through your home network. You can also use your phone's cellular data connection.
