ᐅ Installing Network Cables

Hello,

we are currently building an urban villa with a separate apartment, which my mother will move into. Since we don’t need a landline phone, we want to share an internet connection.

I have little to no knowledge about this matter.

However, I have already heard from someone that I should connect the main router in our house to the telecom connection, then run an Ethernet cable to the separate apartment. This way, the apartment would have its own Wi-Fi, and we would need a DECT phone connected to the main router in our house, if I understood correctly…

Additionally, I want to run an Ethernet cable to the TV to connect it, and I would like a central Wi-Fi setup in the house (we are building with an open gallery). Therefore, I think it will be enough to have a Wi-Fi repeater connected to the Fritzbox via Ethernet cable. Since this will be in the utility room, it probably won’t cover every corner of the house.

Can someone help me with the best way to set this up and what equipment I will need?

I already have Cat 7 cable, which is supposed to be more future-proof ‍♂. It is also clear that I will first install flush-mounted sockets with conduits wherever needed… and then

Thanks to "structured cabling," you can connect the outlet in the granny flat as an IP, S0, or a/b device to the "main router." The connection between the base and handset of the DECT (or cat.iq) phone then takes place wirelessly within the granny flat. I wouldn’t register the granny flat handset directly with the "main router," but rather connect it via the wired connection as you plan.

Nevertheless, I would definitely have a proper connection installed in the granny flat. You never know who might live there in the future...

Is the granny flat KfW-funded?

So the phone would then be connected to the router of the granny flat?

I had understood from an acquaintance that this is not possible, or maybe I misunderstood...

Is the granny flat KfW-subsidized?

No, it is not KfW-subsidized. The granny flat is actually intended to be rented out only in extreme emergencies; otherwise, it is meant as a living space for my mother, children, or eventually ourselves. It also does not have a separate electrical connection—everything will be supplied through our main house and then just redistributed.

Ok, that works for you then.

I still consider it suboptimal and would NOT do it myself, especially with regard to the (resale) value.
