Financing land and house? Taking out a mortgage? Construction costs?

LAN is so last decade, you can just put it in the living room and study or one per floor, otherwise it’s simply unnecessary. Everything runs over WLAN and that’s completely sufficient.

I see it differently. More and more electronic devices, more and more sources of interference. If it’s so last decade, then why go through all the trouble with KNX with cables and not over WLAN? Maybe there’s a reason behind it?

100% daccord, I also don’t think it’s very healthy to have Wi-Fi 1000 times over

The bandwidth of wireless technology keeps up with the requirements of normal users (excluding computer gamers). This also applies to the prediction of further development, because over time we will integrate more and more bandwidth into our daily lives. Wireless technology is easy to adapt, and thus one can easily keep up if they want to use new innovations. If you already lay LAN everywhere, you might as well use fiber optics.

I didn’t want to write anything more here since the main reason of the original poster is actually different. However, I cannot leave the post as it is.

Why are the WLAN subforums in computer forums usually full of messages like: WLAN keeps dropping, slow WLAN, TV streaming via WLAN stutters, WLAN repeater can’t find router, ... There are many normal users looking for help, not only power users.

For a large number of normal users, WLAN will be sufficient, but only if it is available throughout the entire house. Unfortunately, a WLAN router in the house usually does not reach the last corner of the house; often the floor ceiling is already the main problem. Additionally, the 2.4GHz network is now as crowded as never before, and the faster 5GHz network simply does not have the range. WIFI 6 will also not be a panacea. Therefore, WLAN access points are installed to properly get WLAN throughout the entire house. How do you connect the access points to the router? Of course via LAN!

Fiber optics is of course a great technology, but for a normal single-family house there is still no real hardware available and what exists is expensive! From my point of view, LAN will still be the technology over which everything runs for the next decades. At the same time, the LAN components needed are very inexpensive. All stationary devices in my opinion should be connected directly to LAN and thus not take bandwidth away from mobile devices.

Who wants a fast internet connection and the house distribution is the limiting factor!

KNX is still a big oddity, not only because of the costs. For ordinary stuff you don’t need it, that works very well and stable over WLAN.

Very few single-family homes need industrial LAN cabling or KNX.

Thanks to MESH, WLAN is even faster and more stable throughout the whole house.

And there is nothing against a few LAN sockets, as said minimum one per floor. But LAN is very expensive with electricians and therefore offers good saving potential!

Everything runs over Wi-Fi

But Wi-Fi is not "infinitely available." Several devices from 4 people have to share it here, and that is usually not enough.

Thank you very much for the many, mostly constructive responses! Sometimes it just takes a little input from completely uninvolved people to clear your head. In any case, we now know what we will do
