New construction: Connection & cabling Internet + TV

Sure,

is the simplest, fastest, most stable, and most cost-effective option. I wouldn’t even think twice.

And if SAT-IP should become outdated someday, you can always convert it later.

How should I best prepare this conversion now during the house construction if I decide to go with the traditional SAT wiring after all? Should I already lay a CAT7 cable from the utility room near the dish to later easily replace the traditional dish with one that has a built-in converter?

Sorry for asking so often and so dumbly, but I don’t like to rely “blindly” on the statements of experts for things like this. I’d rather understand at least the basics myself to know what to discuss with the electrician.

You could connect LAN to the dish. But I would simply run 4x coax cables from the satellite system to the utility room and then distribute them to the rooms from there. That way you are prepared for everything. You then have SAT in the utility room, LAN as well, and the ends of the cables from the utility room are in the respective rooms for both SAT and LAN. This way you can switch everything as desired at any time.

All right. I will present it exactly like that in our electrical meeting. Then at least I have some idea of what the electrician is talking about.

Regarding CAT cabling, I made a sketch. I hope I understood the connections between patch panel, switch, etc. correctly?

Which internet-enabled devices I could imagine per room:
Kitchen: Radio / Alexa / Sonos
Living room: Worktop in the middle of the ceiling, TV, receiver, PS4, Hi-Fi system(?),
Guest room: PC, printer, PS4, possibly also TV+receiver
Guest WC: Radio / SONOS
Hallway: Doorbell/video system
Gallery upper floor: Worktop on the ceiling
Children’s rooms each: in the "distant" future TV, receiver, console, PC/laptop
Bedroom: TV, receiver
Bathroom: Radio / SONOS

If I understood correctly, according to my sketch I need 20 CAT7 patch cables and 10 double sockets (or do I also have to calculate a socket for a worktop?).
Kitchen, bathroom and hallway on the ground floor are not yet included. There I could— as already suggested here— if at all have cables laid without a socket.
Then I would almost be at 24 cables and a 24-port switch would be fully utilized, right? There probably wouldn’t be any room left for a NAS or something similar.

The costs will probably amount to a few thousand.

(or do I also have to calculate a socket for an access point?).

Yes, of course the access point also goes to a socket. Installation cables are thicker than patch cables.

Then I would soon have 24 cables and a 24-port switch would be fully utilized, right? There would probably be no room left for a NAS or similar.

If it's just about 1-2 extras, the router usually has a small switch built in.

Or you can temporarily unplug the unused ones from one or another double socket in the switch.

Or you change the assignment at a double socket that doesn't require high bandwidth (then both connections of the double socket are connected with only 1 cable, which is still enough for 100 Mbit) and have a free port at the switch again.

Or you simply buy a small, cheap switch and just connect it to the other one.

I wouldn’t install a outlet for the APs. It always looks awkward. With a suspended ceiling, just connect a keystone module to the installation cable and then run only a patch cable to the workspace. This way, no cables are visible at all. Alternatively, a small connector can be attached to the installation cable. Due to the stiffness of the installation cable, this can sometimes be problematic depending on how the connection at the workspace is set up.

Under no circumstances change or split the wiring. Double outlets require two cables or one duplex cable. Use Cat 7 or 8 cables straight away. The cable itself is not a major cost factor. This way, you can upgrade to 10 GB later on.

Most 24- or 48-port switches also have additional uplink ports, effectively giving you two more ports. But with your planning, I would go straight for a 48-port switch.

Personally, I like Unifi. For the workspace, the NanoHD (also available with skins and can be recessed mounted). Unifi switch, Cloudkey, and possibly USG. That gives you all options.

I would rather install the workspace on the ground floor near the kitchen/living/dining area. That way, you have 5 GHz where you spend most of your time. Upstairs, you will mostly have only 2.4 kHz in the rooms (depending on the wall construction). I would rather install one or two more APs or at least provide the connections. But I’m a fan of overkill.

I wouldn’t install a box at the APs. It always looks awkward. With a suspended ceiling, just connect a keystone module to the installation cable and then run only a patch cable to the access point. That way, no cables are visible at all. Alternatively, put a small connector on the installation cable. Due to the stiffness of the installation cable, this can sometimes be problematic depending on how the connection at the access point is.

Alright. I will simply tell the electrician how I want it to look. Hopefully, he’ll come up with the same ideas as you.

Double sockets belong to two cables or one duplex cable

Should I then simply choose the more cost-effective option here? Or are there specific advantages/disadvantages to each?
And should I actually insist that the CAT cables run through conduit?

Cloudkey and possibly USG. Then you have all the options.

That means nothing to me, I’ll take a look at it.

I would rather install one or two more APs or at least provide the connections. But I’m a fan of overkill.

In my current planning, I have one central access point on each floor. That is absolutely sufficient for me. The only things that will run without cables then are things like phones, laptops, possibly music boxes, etc. That should be enough.
