Some of the coordination stuff might help you run multiple APs, but with strong attenuation from walls, you might not have much overlap anyway.
Wifi 7 (6ghz) barely penetrates a single “drywall” wall (in U.S.). It will have a very hard time penetrating thick concrete / brick walls.
in your case if you wanted good wifi 7 signal in all rooms you’d probably need to run wired backhaul and install an access point per room. Probably not worth it. It might make sense to have wifi 7 in your living / dining space though. Especially if you have an open kitchen.
The 6ghz band has poor range but this can be a benefit actually. It means your neighbors 6ghz signal can’t flood your home like their 2.4ghz and 5ghz can. So there’s very little interference on the 6ghz band. This also means a more stable connection and a little lower latency.
If your wifi works well today i wouldn’t bother upgrading. Unless it’s a fun hobby purchase.
The best of both worlds would be to install 6 GHz access points in each room, and run a wired connection between them.
i added the “” because i wasn’t sure if everyone would be familiar with the slang, especially those living outside the US.
AFAIK modern building materials are better for environment, insulation, repairs, build time and cost.
Source: dad was a builder and inspector for 50 years in eastern europe. I’ve grown up in german house from 1890. He’s helping to work on my “cardboard” house in NZ now. Big aspect of course is - houses are built to the local conditions and market, but he loathes block/concrete houses back home. They are being replaced by cardboard homes too.
Drywall doesn't deserve the hate, it's fantastic. Flame resistant, cheap to repair and replace, easy to cut and penetrate to install drops run wires. Wiring my whole house with ethernet was a single day affair because of it.
