Hello!
Our construction started about 2.5 weeks ago, and we are currently planning the electrical system. We are wondering how to install internet in the house.
About the house:
The house is built using solid construction methods from Viebrockhaus. Radio waves barely pass through the ceiling between the ground floor (GF) and the upper floor (UF). On the UF, the interior walls are drywall with metal elements, which also blocks radio waves significantly.
For the ground floor:
We want to set up Wi-Fi with the router located in the utility room. This should provide coverage throughout the entire ground floor and help reduce electromagnetic pollution to some extent.
For the upper floor:
This question is more complex. We lean toward a LAN solution to minimize electromagnetic pollution.
Option 1: Run LAN cables through the empty conduits from the utility room to each room on the upper floor.
Option 2: Use powerline adapters (network over the electrical wiring).
-> We tend to choose the second option because there are more power outlets than LAN ports in each room. It is also somewhat cheaper, though the price difference is minor in a project of this scale.
What do you think? Will this solution work without problems, or are there limitations? Have you had any experience with this?
Thank you very much for your input.

I'm not an expert either, but the more data that needs to pass through, the better it has to be shielded and installed. In my opinion, Cat5 is quite unproblematic, Cat7 is more demanding. I was actually referring more to how the cable is handled; I should have phrased that better, sorry. I had to replace a CAT 7 cable at my own expense because I temporarily fixed it on the wall side with a screwdriver (just moved it aside, of course not damaged) so I could press a heating pipe. It took less than 2 minutes, but after that the cable refused to work properly.

A quick off-topic question from a beginner: Are CAT cables really so sensitive that special care must be taken during installation?
Regards, BauexperteYou shouldn’t sharply bend them, but that applies equally to satellite cables or fiber optic cables as well.
Regarding current usage, would it really make much difference if the cable provided 850 Mbit/s instead of the specified 1 Gbit/s because of a bend?
Since I routed everything through the grey conduit, sharp bends aren’t possible anyway, and it’s also somewhat protected against crushing.

I don’t think it works that way. If the cable is faulty and does not meet the specified limits, the connected hardware will either switch to 100 Mbps mode or there will be transmission errors.
The minimum bending radius for twisted pair cables is usually around 3cm (1.2 inches), and we often use such cables in industrial installations for bus systems. That is actually quite tight. If the cable is not sharply bent around corners (for example, this can sometimes be seen when cables are retrofitted on surface-mounted conduit), it should be fine. It is important that it is not moved afterwards, because typically a solid conductor is used rather than flexible stranded wire.

Peanuts7424 Oct 2016 11:23This probably always has to be considered on an individual basis. For example, there is usually a maximum length allowed for the cable. If you approach this limit, the cable installation must be done “perfectly.” If you only have 10m (33 feet) of cable, you might be able to afford a bend or similar minor imperfection...

I had to manually set the network card down to 10 Mbps. In automatic mode, it detected 100 Mbps, but there were so many errors that loading any pages was impossible.
