LAN / SAT wiring in single-family house

Explanation: The usual (and reasonable) procedure for LAN cabling in the technical room is as follows: All the loose cable ends (which come from the outlets) are "terminated" on a patch panel, i.e. connected. This panel is basically a LAN socket with many ports (8, 16, 24...). The panel itself does nothing with the signal. It only serves for neat routing and easier maintenance. From this panel, you then run (short) patch cables to a switch right next to it (usually with a few more ports than the panel). The switch is the one that actually "makes" the network by connecting all ports only when data is supposed to flow. This completes the LAN. What is still missing is the internet feed. This comes from some modem (often combined with router, WLAN, telephone station...) of a common provider. This modem is connected to the switch, which distributes it to the stations in the network as needed. It should be ensured that the internet feed from outside arrives in the utility room; otherwise, another cable has to be laid. The WLAN, as mentioned above, is often already integrated in the provider's device and can then be used. If not, a WLAN router is needed. It can either be connected to the switch in the utility room or to an outlet at a central spot in the house. For a large house, an additional access point is recommended. This device is also connected to the LAN and creates another WLAN zone (for the basement, garden, etc.). Alternatively, but much slower, wireless "repeaters" can be used.

All the loose cable ends (which come from the sockets) are "laid" on a patch panel, i.e. connected.

Absolutely correct. With only five connections in the house, often plugs are simply mounted on the open ends in the utility room, so the patch panel is omitted. The rest is as you described.

I would always install double sockets, then there would be 10 cable ends in the utility room. I would then lay these on a patch panel.

You have to think in advance about exactly where the patch panel and router will be placed in the utility room. Ideally, you use a network cabinet (10" or 19", wall cabinet) for these devices. Patch panel and switch each require one rack unit (RU) in it.

We bought the cabinet and the patch panel ourselves and put them on the construction site for the electrician. He mounted the cabinet and patch panel and laid the cables.

As previously written, I would always rely on double sockets and on the other side there should always be a patch panel for me.

: Have you ever done a needs assessment for yourself, how many connections you need? For example, in the office with a network printer, network hard drive, and PC one socket would be too few. I see it similarly for the TV.

PS: When setting up the access point, always remember the power outlet nearby.

Always use a patch panel. The ones with 8 ports cost about €30 and can also be screwed to the wall. Not as nice as in the cabinet, but the strain relief from laying it down alone would be worth it to me.

Network printer, network hard drive

If possible, I would park them in the utility room in a house without a basement. Saves the outlets and is out of the way.
With the printer, if it is a laser, all the "toxic" stuff is gone as well.

Otherwise, as the rest say, do a needs analysis and see if 5 outlets are really enough.
For SAT, for example, I would always plan with double outlets. Most devices today have twin receivers (record on one channel, watch on the other).

Is there really still anyone today who records what is running on the box?
