ᐅ Number of RJ-45 Wall Sockets ("Network Outlets") – What Makes Sense?

Hello everyone,
A week ago, we met with the electrician to plan the electrical installations for our new build. Everything is clear regarding the sockets, switches, and lighting outlets. However, we are still considering the topic of communication outlets.
The situation is as follows: Fiber optic cables are being installed in our new development. We want to take advantage of this, but without having to install and pay for too many (unnecessary) RJ-45 (or even TAE) sockets.
As I understand it, in a three-story single-family house you could basically get by with only four RJ-45 network outlets:
Basement: one for the router
Ground floor: two — 1x telephone; 1x Wi-Fi access point
Upper floor: one for Wi-Fi access point.
This way, all end devices (computers, smartphones, TV) would connect via Wi-Fi without using LAN cables. The telephone connection could also be accessed on the ground floor through one of the four RJ-45 outlets.
So, throughout the whole house, we would only need these four RJ-45 outlets (plus 2 satellite sockets for TV). Telephone sockets could be omitted. We plan to do the wiring with CAT 7 cable. In the long term, the satellite TV sockets could be replaced by Wi-Fi TV, according to the plan.
From your point of view, is this planning reasonable? If so, why is it often recommended to install many more RJ-45 outlets when signals can also be accessed via Wi-Fi?
By the way, a home network with only one network printer or other "smart" applications is not currently planned.
Thanks in advance for your replies!

toxicmolotof28 Nov 2017 00:32I read selectively and saw:
And now I had to check if it was really April 1st on the calendar. But it wasn’t.
Of course, different approaches are possible, but! (and this also applies without fiber optic) every wireless network affects the others, and every device impacts the others, even if it just causes slower speeds. (for technical questions please consult the experts)
Now you’re basically getting a Ferrari delivered to your doorstep and say… okay, a gravel driveway to the garage is enough to drive over. Sure, that’s enough, but how about fresh asphalt straight from the Nordschleife? That would definitely be cooler...
With that in mind, anywhere later where a TV, a game console, a PC, a printer, a Wi-Fi access point, or a telephone will be placed, install a double network outlet. If you want some luxury, then also in the kitchen, near the heating (with a connection?), the washing machine, etc.
Sure, it can be overdone, but starting with 8 outlets doesn’t seem excessive to me.
We have:
Living area (3x)
Bedroom (1x)
each children’s room (2x)
hallway on each floor (1x)
= 10 outlets with 2 connections each

Somehow the original post reads as if the electrician is charging exorbitant prices for this work.
I can only agree with the previous commenters. Nowadays, at least one double outlet per room is considered a standard feature, not a luxury.
A quick note on the satellite outlets: Does the electrician install the cables in a way that allows them to be pulled back through the conduits, enabling LAN cables to be run later? Do the satellite cables terminate at the same central point as the LAN cables?
I also think that, for example, basement rooms should be equipped with network outlets. These often become hobby rooms and usually require a good and fast internet connection.
Since a fiber optic connection was mentioned, don’t forget the network outlet near the fiber optic house entry point. Usually, a fiber optic modem is installed there, and from it, a LAN cable leads to the central distribution point.

PS: I’ve been puzzling over how to install a network outlet in our older building’s bathroom with minimal effort for days!

We:
Kitchen – 1 outlet for the refrigerator (might be needed someday)
Living room wall – 4 outlets (TV, receiver, PS4, one spare)
Back wall of the living room – 3 outlets for printer, fireplace control unit, and possibly PC/server
Opposite the living wall – 2 outlets for robot vacuum and telephone
Children’s room and bedroom – each room with a double outlet
Don’t rely solely on Wi-Fi. The outlets aren’t that expensive, and you might regret it later. Plus, you won’t want to add more afterwards.

This is still a big discussion for us. My husband wants to rely more on Wi-Fi than I do.
He wants to run the connection directly from the basement to the living room, place the FritzBox there, then go back to the basement and distribute from there. He thinks it’s enough to have connections in all the bedrooms, the living room, and the office, and let the rest run over Wi-Fi.
I would distribute directly from the basement and place the FritzBox there. You rarely need to access it, so going to the basement is fine. Additionally, I would install a double socket in every basement room, because the concrete basement really blocks signals. It already annoys me that I have no mobile reception there.
I would put 4 sockets on the living room wall. One or two in the kitchen work area (near the stove, coffee machine), and 2 behind the fridge. 2 or 4 in the office and/or sewing room. Two in each children's room and two in the bedrooms. Oh, and I would also put one in each bathroom [emoji16]. And then of course Wi-Fi coverage for the ground floor and upper floor.
My husband finds that excessive. Our construction company would charge 120€ for it. I think it makes sense to do this at the beginning, and have the electrician handle the rest right away. If that gets too expensive, I’d do the electrical work myself with my brother-in-law’s help.
Cables are just cables.
We are having the same discussion about power outlets [emoji85][emoji23].

WilhelmRo28 Nov 2017 09:01Why is Wi-Fi overrated? I live in a 75m² (800 sq ft) single-story home, and everything works perfectly with just one Wi-Fi access point.
Streaming on the TV, four smartphones streaming at the same time (e.g., YouTube), internet radio playing on an Echo device — all running simultaneously for testing.
The range is the same: the TV stream switches to HD within 2–4 seconds, and at the other end of the house, the printer still has excellent reception. Even on the terrace there is full signal, and on the other side, up to 3m (10 ft) in front of the entrance door.
All this with a single Wi-Fi access point.
For a house, 2–3 Wi-Fi access points per floor should be more than enough?
Best regards

Range is the same; TV streaming switches to HD after 2–4 seconds, and at the far end of the house, the printer still has an excellent signal. Even on the terrace, there is full reception, and on the other side, up to 3 m (10 ft) in front of the door.
All this with a single Wi-Fi access point.
For a house, then, 2–3 Wi-Fi access points per floor should be more than enough?
Regards Let me guess. You’re not living with two teenagers, are you?
