Number of RJ-45 sockets "network sockets" - What makes sense?

e.g. internet radio, TV in the wellness area,...

Depending on where your phone connection is. You can also transmit the signal over LAN cable, but it then needs to be a separate cable/socket, so for example 2 cables should run from the basement to the ground floor to allow distribution of the network in parallel.

Then only 100MBit is possible, which can be too little depending on data traffic or, for example, for a NAS. Theoretically, it only costs a few more meters of cable, technology, connections, and channels are already installed anyway.

Many current routers, e.g. also the one from Telekom, already have a DECT base integrated. The question of the connection socket hardly arises.

With double sockets, you have the advantage that, for example, your signal from the fiber optic modem can be patched to one socket, and the router "feeds" your network into the other socket. This way you can operate your router at any desired double socket in the house. Also: A network device rarely comes alone.

100 MBit in cable sharing is state of the art from 20 years ago. Today the only question should be whether your cabling can do 1 GBit or 10 GBit.

Last but not least: Our electrician charged the general contractor 95 euros net per double socket with cabling. I would have paid 200 too...

You might just not understand that jet now. In ten years you might see it differently, which is why a conduit should be installed there. Of course, it may be that you then understand it but still ultimately hold the opinion that you don’t need or want it. Then the conduit remains empty. That is better than having to break open a wall later. In ten years every milk carton will have an RFID 5.2 chip with its expiration date that the refrigerator can read. Only people whose refrigerator cannot communicate will still have sour milk.

Even over fiber optic, you could still use a rotary dial phone. TAE is simply a standard whose obsolescence is already foreseeable.

Sort of. Cable sharing dates from before gigabit. Back then both IT and telecommunications end devices only needed four wires and could therefore share eight wires amicably. An IP phone then only relies on 100 Mbit Ethernet, which is sufficient for it and if it is not supposed to switch a gigabit device, that does not matter. But the second cable can be laid beside it for little money without noticeable additional time = labor.

Personally, I nowadays also recommend “structured cabling” to private users but I admit that you can be happy with less as well.

My motto is, once the plaster is on, it should stay on. Although conduits are sufficient, you don’t have to overdo wiring for the next decade right now.

One more thought about the conduit. But you can also consider how easy it is to pull a cable later through a conduit, whether it is a green bus cable or a significantly thicker CAT 7 cable, if it makes more than one, let’s say even two 90-degree bends. Before I take the risk of ending up with a beautiful conduit under the plaster but not being able to install anything in it, I would have the cable laid right there if the bandwidth is needed for the refrigerator.

I am of the opinion that audio streams for background music in the shower with a Sonos, as little as a refrigerator, necessarily require a wired connection. WLAN is completely sufficient. Where it makes sense (multimedia, video streaming, workstation for image/video editing) I would definitely go with cables, for occasional use with little traffic (audio streaming, refrigerator, mobile devices) WLAN is enough.

The same applies to conduits, where it makes sense and where you can also get the cable out and back in again gladly, but certainly not when it’s about 25 corners... then the network cable will almost certainly no longer go through... if at all the pull wire [emoji4]

Thank you for the hint – I keep suppressing that the term empty conduit is popularly imagined as the most stingily dimensioned toy variant. The more you want to use this variant, the more important the junction boxes naturally become in an empty conduit system, which then become indispensable as crossing points. The thinner the tube, the more critically the bending radius must be considered, or respectively, an inspection opening must be available at direction changes.

For houses without a basement that may be true, but for all others the router is usually located exactly there and then there is no DECT from the router upstairs anymore. That is exactly the problem we currently have, after switching from microwave radio to VDSL and the router has moved from upstairs to the basement, but the telephone is supposed to remain in the living areas.
