Construction costs are currently skyrocketing

So who had WiFi or a mobile phone 20 years ago? Certainly very few.

20 years ago I was still a student and mobile phones were an important topic. The majority of students had one. And among the general population, it must have been over 50%. WiFi already existed, but was uninteresting to us students. Instead, people tended to discuss BNC vs Ethernet for the next LAN party.

Nobody could have imagined that there would one day be Magenta TV

When I started studying nearly 20 years ago, the full satellite TV program was streamed into the university network. Multicast, receivable on any PC with VLC, there were even a few test programs in Full HD. At that time DSL was just starting, but as a student you had 100MBit privately, even in upload! Back home one was always eagerly awaited with all the backup copies :D

If I have the choice, I always prefer solid wiring for bus systems and networks over wireless solutions.

I basically agree with you, but when I still see the permanently installed ISDN sockets in the desk in some hotels today, the USB sockets, etc., and of course also LAN sockets, I wonder what of that is made to last for the duration you normally spend in such a building in your lifetime. You can change a wireless standard more easily than sockets and wiring. We laid CAT 7 cables in almost all rooms three years ago, but hardly use them.

Please tell us what your WLAN concept looks like as a whole.

Indeed, we have an access point in the garden, not just for mobile devices. In the age of IoT, that is eventually indispensable.

The problem is as follows. Technological developments happen so fast that you can no longer plan 10 or even 20 years ahead today. So who had WLAN or mobile phones 20 years ago? Certainly very few. Nobody could have guessed that Magenta TV would exist one day.

I think it’s important today to install enough empty conduits for future applications. In floors, walls, and stories.

I absolutely agree with you, we have planned empty conduits in the house and garden, high-voltage power is connected in the garage, who knows what else will come. We didn’t even install a satellite dish; we also use Magenta TV, etc., everything only via the internet now.

Most comments reinforce my opinion that LAN will become unnecessary for me.

Not everyone can see the difference between HD and 4k on the TV from x meters away.

That depends very much on x and especially the size of the TV. ;) The resolution capacity of the human eye basically does not vary much from person to person, so you can calculate all of that well - if you want to. If you don’t care, of course, that’s the end of it.

:D Anyway, the demand strongly correlates with the acceptance of Wi-Fi for everything.

I wouldn’t even agree to that. I stream 4k movies via Wi-Fi without any problems. The bottlenecks are much more likely the connection to the house and the providers’ servers.

WiFi 6 will establish itself in the next few years. It offers data rates of up to 11 Gbit/s. Theoretically... but even the practical number will be so high that you will hardly overload your own house connection.

We take the middle way: on 150 sqm, 4-5 Ubiquiti APs well distributed to LAN sockets. The in-wall APs then also have 2 LAN sockets integrated, in case you need to connect something with a cable after all.

4-5 LAN sockets are reasonably inexpensive.

When I see photos where 10 sockets and 4 LAN sockets are stuck side by side on all walls, it shakes me internally. Always with the addition "in case you ever need it. I don’t like power strips." Absolutely not my taste. I’d rather cleverly put a power strip in the cabinet, don’t see it, and also don’t have to look at a sea of sockets where no piece of furniture stands.

But to each their own.

Most comments reinforce my opinion that LAN is becoming unnecessary for me.

If only WLAN anyway, then the implementation like at moHouse can only be recommended. Just one router for the whole house is a thing of the last millennium.
