Alien Mesh - No Dedicated Backhaul?

Frank Here

Please advise :
If I use Multiple Alien routers ( 2) to form a Mesh network, It is my understanding the routers ( then) talking to each other DO NOT create/have their own dedicated backhaul communication between them. Then the routers would I assume create a separate virtual network on the Wi-Fi 6 band...this would SHARE the bandwidth of the main network - doing two jobs at the same time.

The communication between both Routers
the general communication of all the devices using the network.

If this is correct , it seems, there will be a performance hit as the routers are doing two jobs ( without the dedicated back haul line of communication between each of them)
Can you inform me if :
a. this is accurate ?
b. is there another setting to have a dedicated backhaul between the two ?
c. What Am I missing? Is there some technology that is occurring that minimizes/eliminates any of the signal loss that will/can occur?

Please advise,

thank you!!!

@frank-here Yes it can do a backhaul.

Hi @UI-Brett - does the Alien support MU-MIMO Uplink, either WiFi-6 or AmpliFi propriety?
Is it then possible to have a simultaneous 4x4 5GHz wireless backhaul along with client access?
Thanks
