Network installation single-family house: Roaming between APs

Hello everyone,

we have a single-family house (new build) and I am currently dealing with the proper installation for a decent Wi-Fi. The following key points initially:
Wiring: Cat7
Area per floor: 50 sqm
Basement: fiber optic connection, network cabinet, patch panel, Speedport router
Ground floor: 2 network sockets to choose from, for connecting an access point (PoE or power outlet)
Upper floor: network socket in the hallway for access point with PoE
Attic: network socket on the ceiling for access point with PoE

It is especially important to us that roaming between the APs works well.
Could I simply connect 3 Ubiquiti Lite, one per floor (basement is neglected)? Do they need to be specially configured?
Another question: can I simply connect a PoE switch for the PoE components after the patch panel?

Thanks in advance

Hello Hensgen,

you can actually answer all your questions with yes :)

Otherwise, for better understanding, you might want to take a look here, for example:

If you have further specific questions, you will certainly be helped here.

Better the NanoHD than the Lite because of the speed. When roaming, the client decides, not the access point. Usually works well per floor without detailed configuration. Important to set the APs to different channels. Be sure to provide a connection in the basement. Many devices today have Wifi or LAN.

And I always say: equip the garage too

And don't forget the garden either.
