New construction: Connection & cabling Internet + TV

The Keystone module is like a small socket into which the patch cable is plugged. It is also used in higher-level patch panels so that these can simply be plugged into another or different place. You don’t have to remove the installation cable and re-terminate it. Since the module is quite small, you can simply cover the hole in the ceiling with the access point.

Duplex is usually cheaper because it is laid as one cable. Otherwise, there are no advantages or disadvantages. You can also lay everything with single cables. Possibly cheaper depending on the required quantity and if it matches the roll size. I would prefer empty conduits. If you want to change something later, it is much easier.

Unifi is a centrally managed system. That means you can configure all switches, APs, routers, and networks in one app or page.

The controller runs on the Cloudkey. But it can also run on a server, NAS, etc. Then you don’t need a Cloudkey.

USG is the designation at Unifi for the router.

In a complete Unifi system, you can realize a lot very easily. Multiple networks (e.g. management, productive, guest, camera, building technology, access control, kids...). Accesses between them can be set through firewall rules, times, speed, etc. Multiple WLANs similar to the networks VPN Overview of the network Blocking of certain websites Central updates and backups of the system and much more.

I can also take a few pictures for you. I currently have (part of) a complete system here for a friend’s new building.

Where do you use the laptop most? The access point should be as close as possible here and with line of sight. Otherwise, the 5GHz coverage is poor and you are on the slower 2.4GHz network. On the ground floor, definitely place the access point in the living/dining room.

Under no circumstances change or split the wiring. Double sockets require two cables or a duplex. Lay Cat 7 or 8 right away. The cable itself is not a major cost factor.

Of course, "normally" one does not do that. It's not about costs, but a solution approach in case the OP ends up missing exactly one port at the end of the day. That actually doesn't hurt, not every device needs GBit LAN. By the way, almost all the general contractors we have checked install it this way as standard.

Have you ever thought about cameras? I would also lay a cable to the potential locations right away. Having is better than needing. And cost-wise, it doesn't make much difference.

This is what a keystone looks like:

Where do you use the laptop most? The access point should ideally be close by and have a line of sight. Otherwise, the 5GHz coverage is poor and you are on the slower 2.4GHz network. On the ground floor, the access point should definitely be in the living/dining room

We will probably mainly use the laptop in the living/dining area, but certainly also sometimes outside on the terrace, which is directly adjacent to the living room. Maybe also sometimes in the corner of the property where a barbecue hut is planned. The question is whether the access point in the living room would reach that far. Upstairs, later on, a laptop might be used by the children. But there are even two double sockets planned for that. And if the laptop is carried around (to the bed or something), then we have the access point in the gallery as centrally as possible. An access point in every room where a smartphone/laptop might be used sounds exaggerated to me.

I have a single Fritzbox in the utility room. WLAN reaches into the garden and partially onto neighboring properties. The house is solidly built with a reinforced concrete ceiling. WLAN is also available on the upper floor.

I keep wondering what the paranoia about millions of access points in a single-family house is supposed to be about.

For 300 sqm and larger, it might be worth considering, but more than one access point per floor in a typically sized house is definitely enough. It also doesn't necessarily have to be in the living area. Somewhere central on a wall or ceiling is completely sufficient.

Depending on the glass, the signal may be almost completely absorbed. No problem with open doors. Just lay a cable to the terrace. If it is not needed, you can still use it for a camera. If the signal is too weak, just put another access point outside. Maybe someday a robotic lawn mower with WiFi? You'll be glad to have coverage then. But I think you're well served with one access point in the living/dining area and one centrally on the upper floor. The rest then by cable. If usage changes in a room or you need more WiFi speed, you can always connect an access point to the socket.
