Hello everyone,
I think my question might be a bit silly, but I haven’t found an answer yet, and I might be searching in the wrong way, so I wanted to explain my situation.
In our house, we have installed Cat 7 cables on 4 floors with the corresponding network outlets (RJ45). All these Cat 7 cables lead to the connection room in the basement, where the main telecom connection will also be located.
Now, the internet/telephone/TV service from the telecom provider enters the connection room.
Here is my actual question: I assume the Cat 7 cables will be connected to the "internet" in the connection room. However, we want to place our Wi-Fi router on the ground floor, so NOT in the connection room. Is this even possible?
On the ground floor, where we want to place the Wi-Fi router, the following connections are available:
1 x network outlet (Cat 7)
1 x telephone
Sorry if this is probably the most basic question ever, but I really don’t have enough knowledge about this.
Thank you very much.
Best regards,
benkler1401

Of course they will... why should a house inhabited by two people, with a tablet, a PC, and two iPhones, and where the lights are controlled by a light switch, need something like that? Karsten If that works for you, then of course that is legitimate. However, generally, you shouldn’t advise someone who is building new to do that.
It is hardly understandable that the electrician doesn’t want to install a duplex outlet here and then only does the absolute minimum.

The fact that the electrician doesn’t want to install a duplex outlet here and then only does the bare minimum is hardly understandable.To you as well: what should one advise or not advise the homeowner?
I don’t understand this at all!
Does the house work without it, or how, or what exactly is meant?

The recommendation:
Each room should have a double network outlet. The cables should end in the technical room or a similar location on a patch panel. This allows you to decide what is connected to each cable. This does not have to be limited to computer networks, as this type of wiring is quite versatile and can replace other types of cabling.
All stationary devices (computer, TV, gaming console, heating system, kitchen radio) and workstations (connection at the desk for a laptop) should be connected via cable. Wi-Fi should be reserved for mobile devices (smartphone, tablet, laptop).
Why?
Wi-Fi is a shared medium. This means all devices share the bandwidth (the speed). So, if two devices use Wi-Fi at the same time, each effectively gets only half. You also have to consider neighboring Wi-Fi networks, even if their signals are very weak. They interfere with the home Wi-Fi and reduce its bandwidth.
Wi-Fi only reaches the stated speeds under ideal lab conditions. In reality, you usually get only a fraction of the possible bandwidth.
For the same reason, repeaters are a bad idea because they cut the bandwidth in half. Instead, an access point should be used if necessary.
A concrete example from just yesterday:
Mom is watching Netflix while scrolling Instagram on her phone. Dad is on his laptop surfing the internet. Son is watching Netflix and has Skype running with friends. Meanwhile, videos keep streaming in on Snapchat. And they all complain that the internet is slow and the Netflix stream keeps buffering. A quick check showed a 100Mbit internet connection not even close to maxed out. The Wi-Fi, however, was overloaded. Plus, five other neighbors’ Wi-Fi networks were on the same channel. The solution: Connect the TV via cable, and everyone is happy.
Furthermore, other wiring can be eliminated: telephone sockets become unnecessary as you can distribute telephone service over this network cabling. Most people already use cordless DECT phones anyway. Current telephony runs over VoIP. You can already connect a phone via VoIP over the network, for example, using a relatively recent Fritzbox.
You can even do without traditional TV cabling and instead rely on IP-based technology, such as Telekom Entertain or Zatoo. Or where available, DVB-T. Satellite would also be an option, though I would currently only recommend this to technically experienced users.
The trend is clearly moving towards streaming and away from traditional TV and radio. I often hear people say they don’t watch TV anymore because they have Netflix. And when cleaning, Spotify plays cleaning music, while relaxing music plays in the bathtub.
Finally, the network can also make it easier to retrofit sensors for an alarm system.
Of course, a house can function without network cabling—just as it can without TV cabling, with only one power outlet per room, and a single fixed-line phone in the hallway. But that is no longer considered state of the art.

Since you have two solid conductors side by side, you can only run them along one axis, behaving like a ribbon cable. Instead, it’s better to pull two individual cables through an empty conduit and install them that way. But the point remains: One outlet is never enough. Always use double outlets.

Wi-Fi should only be an option in exceptional cases, as mentioned above. In all other situations, wired connections should be used whenever possible. This is especially important in new builds.
