Connection of additional telephone sockets for internet throughout the house

Thank you very much for your assessment.

I wonder what the electrician intended with that. The house is less than two years old. What purpose could that serve?

Ultimately, I am not necessarily dependent on it. The Wi-Fi coverage in the house is not bad. Since the cables are positioned as if they should or could be connected, I had assumed that a short-term improvement might be possible there.

Honestly, you have to ask your developer. I think the electrician only did what the developer wanted.

You write that on one side the WLAN is OK, but you want to have something improved. What improvement are you thinking of?

In general, I wonder with the pictures and the parallel post whether the developers are stuck in the last century.

Oh, they probably just order a certain density of sockets per floor and that's it. Then the lighting current electrician, who has no clue about ITK, has read something about Cat.7 and just lays it on a/b of TAE sockets – as socket wiring, of course.

To be honest, you have to ask your developer. I think the electrician only did what the developer wanted.

Well, I have a WLAN connection in all parts of the house. However, the signal decreases upstairs and out into the garden. Therefore, I thought that this multitude of cables must be good for something and thought that I could create a LAN connection in other rooms via the sockets if the cables are just connected. However, if that would involve complex measures, such as pulling new cables or similar, I probably wouldn't do (or have done) that at the moment. I have already been able to achieve improved signal performance via powerline. Under these circumstances, there is therefore no urgent need for action.

From my lay assumption, it looked as if the cables "only" needed to be connected and had a concrete use.

From my layman's assumption, it looked like the cables "only" required one connection and had a concrete use.

That is not a layman's assumption, that is the pure truth. Each of these cables creates a connectionMöglichkeit. But firstly, one does not want to use all possibilities, secondly, the installer does not know which one will be chosen, and thirdly, a "to what" is also needed for the connection.

This is not an amateur assumption, this is the absolute truth. Each of these cables provides a connectionpossibility. But first of all, you don't want to use all possibilities, secondly the installer doesn't know which one will be chosen, and thirdly you need something to connect it to.

It may be true that the installer doesn't know what will be done with it later, but choosing a JYSTY cable instead of a CAT cable still isn't logical.

What does a CAT cable cost more? At most probably 0.5€/m or even less.

The work was even done to wire rooms in a star topology, which is enough for a minimal LAN setup. Unfortunately, cables from the last millennium were used. I also don't understand the BT not pushing harder on this. You could sell it as future-proof.
