Why don't construction prices go down?

I am already sure that the expensively paid (170 EUR net each) data outlets in every room are never used, at most the ones in the study to extend the Wi-Fi upstairs.

170 is a bargain, in my memory it would have been 80 for the empty conduit & outlet plus 220 for the LAN cable, duplex outlet, wiring at the outlet and wiring at the patch panel. I then did that myself as an after-work project and now have 120 ports in the single-family house plus (currently unused) fiber optic lines, satellite, speakers and a separate electrical circuit.

Of course, only a few of the 120 ports are used – but time and again I realize: Hey, I’d really like a Wi-Fi/Zigbee/whatever repeater right here or would like to game or whatever. When school was closed due to corona, I simply put a laptop for the junior on his desk, patched the LAN cable, done. There is currently no Wi-Fi in the bedrooms.

So the investment in network infrastructure is never bad. Ask the people who built a house a few years ago and only have a telephone line as their sole data connection. In property valuation, "network infrastructure" is now an important value criterion. So well-invested money, especially at that price.

They let Telekom install fiber for 899 EUR, if possible. And if it's not possible, even 120 ports won’t help you.

The investment is complete nonsense, especially in 120 ports. My company recently built new, and do you know how many of the hundreds of network ports at the workstations are still connected? 2 in our office, because we have special software that we can't get into the company network via Wi-Fi. The entire rest of the building is only connected via Wi-Fi, all LAN ports are dead.

So much for your good investment.

We will see – currently I have not regretted a single Ethernet port. I did the wiring for the lifespan of the house and not just for the first two years. Of course, I also pre-installed fiber optics. And a mesh Wi-Fi throughout the whole house/garage/garden, plus Zigbee. I am quite aware of the advantages and disadvantages of the systems.

I can only laugh heartily at a blanket statement like "nowadays everything is done over Wi-Fi." In the private sector, yes, and even more so in the commercial sector. At work, we are rather considering laying fiber optics to every workstation.

120 ports in a (large) single-family house is certainly extreme, sure, many of them are not fully patched but only at the patch panel and the other end is hidden under plaster. So the investment was marginal.

If you are annoyed about your investment – well, sorry for you. I enjoy mine every day and have had it confirmed in black and white during the house appraisal. In the law firm, we recently had some clients with watery eyes because their properties were devalued due to missing network infrastructure – not by us.

Enjoy your Wi-Fi, I enjoy my LAN/Wi-Fi/Zigbee.

ein Mesh-WLAN

120 network ports and then Wi-Fi as mesh?
I don't understand that...

Glasfaser an jeden Arbeitsplatz zu legen.

Have you ever seen an end device with a fiber optic connection?

Freu Du Dich über Dein WLAN, ich freu mich über mein LAN/WLAN/Zigbee

I agree with that!

At the moment I have eight Wi-Fi APs here as a mesh so that I can (which I actually do quite often) move through the house during video conferences. The different networks are separated at the access point via VLAN.

For the housewife in the three-room apartment, pure Wi-Fi might be fun and you can build a little something with powerline etc. Professionals just need a bit more hardware in the basement and for various reasons one also prefers not to send some things over radio.

As soon as you use PoE, Wi-Fi really becomes quite difficult ;)

*Eyes opened* yep, I’m writing from one. At the university, desktop devices already had fiber cards inside 20 years ago. It’s not rocket science.

But that’s not the point. The point is that during the construction phase you can easily install many things inside the walls that you can’t later. I also laid a power cable in every bathroom (and we have four) without any connection in case I ever buy a luxury toilet. Investment? 15-25m of cable (depending on the floor). On the terrace, only the Ethernet cable sticks out of the wall and if I ever connect a PoE PTZ camera, it’ll simply be patched in. Many things turned out differently after moving in; for example, I swapped the positions of the “dining table” and “TV corner” in the living room. I was pretty glad about that because I had laid the necessary cabling at both possible positions.

At the latest when using PoE, WLAN really gets difficult ;)

But that’s not what it’s about. It’s about the fact that during the construction phase, you can easily put many things into the wall that you can’t do later. I also laid a power cable into every bathroom (and we have four) without any connection in case I ever buy a luxury toilet. Investment? 15-25m cable (depending on the floor).

We are usually two people working from home and sit in video conferences all day. My wife works on the second computer simultaneously via VPN on the company server and processes very large files there. Meanwhile, Alexa plays music quietly in the background, the kitchen machine cheerfully fetches recipes from the internet, and surely a TV box with 4K from the night before is still on because we forgot to turn it off. At the same time, we use WLAN telephony on the phone because there is poor mobile reception in parts of our apartment. All this works over WLAN without additional LAN sockets or other cables.
