In a pure Wi-Fi Backhaul network:
All the Deco units are connected through the Wi-Fi backhaul connection. In this case, we recommend no more than 10 Deco units in the network to ensure Wi-Fi performance. Also, we recommend no more than three hops in the networks.
Note: A hop is a trip that a data packet that is transferred from one Deco unit to another Deco unit.
In an Ethernet Backhaul network:
All the Deco units are connected directly through Ethernet cables or a network switch. And all the Deco units will communicate through the Ethernet connection, without the Wi-Fi Backhaul connection.
In this case, you can add as many Deco units in the network.
In a Hybrid network:
Some Deco units are connected through Ethernet, while others are connected through Wi-Fi. In this case, we recommend no more than three consecutive Wi-Fi hops in the network.
