LAN network single-family house procedure

Hello everyone,

We are planning to start building a new 160m² single-family house without a basement using timber frame construction in the middle of next year. To save costs, I would like to take on part of the electrical installation myself (connecting sockets and pulling cables) and am therefore currently dealing with the topic of home networking. I am actually a layman in this field but am trying to familiarize myself with it as best as possible and understand the whole thing. I have the following idea but am very open to suggestions and constructive criticism:

The goal is to install a WLAN router, telephone, and video intercom in the hallway (central point in the house). The WLAN router should mainly be used for mobile devices. In all other rooms, I would like to install one or more LAN sockets (a total of about 14). In my opinion, connecting devices via LAN is much more stable, future-oriented, and should result in significantly less radiation in the house in the end.

That’s what I imagine. As I said, I am very open to other opinions. Now it’s about how to implement the whole thing... Below is a list of how I would approach it, with a request for you to chime in or correct at the relevant points.

[*]The network operator installs an APL in our utility/technical room and from there the first TAE


[*]Lay network cables (Cat 7) from each network socket in the various rooms (for double sockets --> 2 cables) into the utility room


[*]Place the cables that come together in the utility room on a patch panel


[*]Now connect the patch panel to a switch with patch cables


[*]Now connect the switch to a DSL router with a patch cable. Are there recommendations which routers are suitable?


[*]Now the router is connected to the first TAE.


[*]The WLAN router, which is to be located in the hallway, is now connected via a LAN cable


[*]The telephone is connected to the WLAN router

Does all this work that way? My first question is already about the two routers...? Are two really necessary? Wouldn't I then have two WLAN networks? Or are there also routers that “only” establish the connection and do not broadcast WLAN?

I am very curious about your answers and comments ☺

Thank you very much and best regards

Dennis

Does all that work like this?

Yes, it does.

TAE1 => Modem => Switch => Patch panel => LAN socket

My first question is already about the 2 routers...? Are two really necessary? Don’t I then have two WLAN networks? Or are there routers that "only" establish the connection and don’t broadcast WLAN?

You have to differentiate here a bit. Modem/Router/Access point etc.

The important thing is at TAE1 you need a modem that establishes the internet connection; there are ones without WLAN (etc.) or you can disable the WLAN.

The WLAN router in the hallway - should be your access to the WLAN - here the question is pure Access Point (WLAN only) or also DHCP, telephone system, telephone connection (TAE/DECT), etc.

My plan will probably look like this:
Modem-Only => for the internet
Firewall (Unifi USG) => DHCP, etc.
Switch (Unifi)
Patch panel
Hallway: Access Point (Unifi)

Note: I haven’t thought through the telephone system point yet. (e.g.: telephone system (FritzBox with only telephone activated (no modem, WIFI, etc.)) In case of emergency modem/telephone system FritzBox and the Unifi USG in the exposed host and then I only have to distribute DECT on ground floor/upper floor. Or I install a FritzBox on the ground floor with only DECT and a pure modem in the tech room.

The general approach is quite good.

If I were to do it, I would do it like this:
- Fritzbox in the utility room for LAN and telephone.
- a central access point (Unifi) on the ceiling for each floor, possibly only one in the house is enough. In any case, provide a LAN connection for an access point on each floor. Power supply via POE from the utility room.
- Which phones should be integrated? Hardwired or DECT? DECT can be logged into the Fritzbox. If the DECT coverage from the utility room is not sufficient, simply place the base station centrally in the house and connect it to the Fritzbox TAE port via a LAN socket and adapter cable. Hardwired can then also be connected to the FB TAE port.
- If you lay the cables yourself, then install LAN double sockets everywhere right away.
- TV or office can also benefit from 2 x double sockets. Just think about what you want to connect. For example, the hobby room often requires a good LAN connection.
- Video intercom system? Which one? The wiring depends on that.

To save costs, I want to do part of the electrical installation myself (connecting sockets and pulling cables)

Pulling cables is basically fool’s work, I see little potential for savings there. Installing boxes and wiring them up is a bit more demanding.

Actually, I am a layman in this field

With the terminology differences Router / Switch / Access Point and the like, probably yes – but judging by the procedure list, your virginity as a layman has already been a little torn.

With double sockets, remember to wire them twice as well.

Also pay attention to empty conduits; really empty in the sense of reserve, not just pulling tunnels that are already full with one cable.

And have a look a bit to the right and left, today there were three new wiring threads.

- Video intercom system? Which one? The wiring depends on that.

I was thinking of an IP video intercom system. I don’t have an exact overview yet of which one. Any recommendations? I’m also looking for a solution that is future-oriented. That means I always prefer solutions that are still state of the art in a few years and can be replaced relatively easily in case of defect etc. without needing to rewire.

Regarding the distinctions between router / switch / access point and the like, probably yes – but judging by your step-by-step list, your virgin membrane as a layperson is already a bit torn.

That pleases me, that I am not completely on the wrong track ☺☺☺

Otherwise, thanks for your answers – I definitely made some progress.

I cannot give any recommendation regarding video intercom systems. It was only meant as a note to provide the appropriate wiring.
