Network Cat 7 - What is it?

If the OP wishes, I will gladly do that. Otherwise, I am actually pretty indifferent about it.

You probably mean Cat5e, right?

What works easily on a small scale with Cat5e unfortunately is not always possible on a large scale in home wiring. Please don't take it the wrong way, but I have to draw the line somewhere between free advice and paid service. Therefore, here is only a superficial short version. In home wiring, even with perfect cabling, a considerable cable length accumulates quickly. On top of that, there are various sources of interference.

Fortunately, no advice is needed here anymore ;-)

Please don't take it amiss, but somewhere I have to draw the line between free advice and paid service.

I think you are in the wrong place here!

On the topic: I also believe that using Cat 7 is like shooting sparrows with cannons, but if it's included anyway, then everything is fine.

I wasn't concerned about what is better. As I said, Cat 7 is included.

What my question was:
Where it makes sense and what you can do with it, since I have never dealt with it.

But thanks for all the answers.

So I will have, besides the intended outlets (children's room, office), one installed in the living room and maybe one more in the dining room.

Only with the patch panel, I will come back to one or the other.

My goal is to network the house so that the children (someday there will be some) can print downstairs later and that I can access my hard drive in the office via network cable with my AV receiver in the living room. (It has a network input)

An additional WLAN router will still be used. For laptop, phone, etc...

What kind of patch panel do I need then?

5 outlets, 3 PCs, 1 AVR, 1 WLAN router

The number of ports on the patch panel is solely determined by the number of outlets. One outlet has 2 "connection points," so you need 2 ports on the patch panel per double outlet. 5 double outlets = 10 ports

So can I plug two things into each socket? For example, a laptop and a PC in the office? I always thought that was input and output! :(

You then need 2 cables per double socket (or you split the 8 cores across both connections, but then you no longer have gigabit). Input (RX) and output (TX) are at least up to 100mbit the cores 1,2 and 3,6 I only know patch panels (19") with at least 16 ports
