ᐅ How can I set up Wi-Fi and telephone services, as well as technical installations, in the basement?

Hello everyone,

Since I am a complete beginner in the IT field, I’m asking for your help.

We are currently building a semi-detached house. Because of the underfloor heating, I have planned a CAT7 connection on every floor.

Now I’m wondering how I can later provide Wi-Fi and telephony throughout the house.

The incoming service line is located in the basement.

How can I distribute the telephony and Wi-Fi in the house using a FritzBox? I was thinking of installing an access point at the CAT7 outlets on every floor where needed. But how do I get the LAN connection there? Is it enough to connect the FritzBox in the basement to the network ports that end at the CAT7 outlets and then set up access points?

Also, I need to know how to connect a telephone (which will be located on the ground floor) to the FritzBox that is in the basement. Maybe Wi-Fi telephony?

Sorry for my awkwardness and many thanks for your help!

I have already been involved in the full automation of a three-family house, whose PLC communicates via several 20-conductor telephone cables with a large collection of sensors and actuators, running trouble-free for over ten years. Professionally, I design telecommunications systems; I am not involved with HVAC, but I am happy to learn more.

Well then... that's why I’m asking (and still not quite sure). Sometimes trying to be funny can feel forced. But anyway. The original poster already considered during planning that Wi-Fi from the basement with underfloor heating might not reach the entire house and that access points would be necessary. Hence the connection between underfloor heating and Cat 7.

you actually meant, "I had network wiring installed on every floor to avoid accidentally drilling into the underfloor heating when making holes in the ceilings"? — well, that would explain my confusion about the supposed connection, and we agree that for the control of the underfloor heating itself, even doorbell wire is sufficient for the control signals, which are far below Btx baud rates, despite what was said in the April issue of c’t.
Well, that reassures me and I don’t have to fear that the world has suddenly gone crazy and I’m just finding out about it again hours late. The same goes for your worry that I’m really as humorous as I pretend to be.

Yes, this is naturally only about underfloor heating itself, which in some cases should not only be left unpunctured but, depending on how it was installed, can also be a significant source of interference for all kinds of wireless signals.

This is what I understand from the thread title...

Actually, I only have one CAT7 cable per floor. The guest WC, kitchen, bathroom, and bedroom do not have CAT7 outlets – I think they are not necessary there. I thought Wi-Fi would be enough (or not)? In the children's rooms, there are prepared empty conduits.

Regarding the underfloor heating, this means that due to the shielding effect of the water in the heating system, each floor was taken into account.

As I understand it, I can connect the FritzBox in the basement, then link all the CAT7 outlets to it (physically, we are still in the basement). On the ground floor, I will use another FritzBox for Wi-Fi and DECT telephone service. On the two upper floors, I plan to install access points (does anyone have product recommendations?). The empty conduits for the kids will remain unused for now. I wonder if the CAT7 outlets will still be usable by the time my daughter is old enough for the internet (she will be two). Is this setup sufficient for average household use (browsing, streaming, Amazon Echo, and my wife’s Thermomix)?
