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!

There is no need to demonize Wi-Fi. However, cables should be used where large amounts of data are frequently expected. For appliances like refrigerators, I consider it unnecessary; even an audio stream, in my opinion, is not something that must be handled with cables. Plan one access point per floor, and run cables to the ceiling accordingly.

Deliverer28 Nov 2017 11:28Well—it's probably the same as with many things... For those who only use apps and browse the internet, Wi-Fi is enough.
But as soon as you need to sort through, edit, and save 500 vacation photos, Wi-Fi becomes too slow. Streaming videos? Forget it. And when the kids want to play games, they’ll definitely complain to dad about Wi-Fi and ping issues. And how many times in my life have I heard, “The Wi-Fi isn’t working,” “Try restarting this or that,” and “XY has no connection”… That doesn’t happen with wired connections. (Unless the cat has pulled the cable out again…)
Of course, there are really good, fast Wi-Fi devices nowadays. But they not only cost more than wired connections, they are also less secure and rely on updates. And the faster and higher frequency they are, the more the signal is weakened by walls, meaning more access points are required.
So no. Wi-Fi is for devices that fit in pockets or at most handbags. Work devices need wired connections.

Exactly what Alex85 described: use cables where bandwidth is needed, otherwise Wi-Fi is sufficient.
When it comes to video editing, in my opinion it doesn’t really matter whether it’s over cable or Wi-Fi — I would never consider doing serious video editing on a network drive anyway... though that’s probably not a use case for most people.
Also, I wouldn’t transfer a 32 GB (about 34 US quarts) SD card full of images over the network; I’d copy it directly to the NAS, regardless of using Wi-Fi or cable. But that’s more of a personal preference...

Deliverer28 Nov 2017 12:07Since a decent NAS is almost as fast as an internal drive, you can definitely go that route... Of course, it runs a bit smoother on the built-in SSD... Luxury problems.
And the photos from the memory card will definitely be transferred over the network to the NAS. First, I don’t want to walk into another room (that’s the whole point of LAN...), and second, the card and card reader would need to deliver more speed than the network can handle, which rarely happens. Besides, I don’t want to move the files somewhere else, but directly into the correct folder.

Where does it make sense? Have you ever connected a LAN cable to an iPad or something similar?
If you already have FTTH (fiber to the home), as we do, it’s a good idea to install several double sockets.
The future is uncertain, but I expect wireless, such as Wi-Fi or radio, to dominate. LTE/5G is already quite capable.
However, at the TV, having two double sockets is practical, and the same applies to a home office, if you have one. With a printer connected via LAN and a NAS or laptop as well, the sockets will be in use.
We have TV with 2 double sockets, next to the TV wall in the living/dining room another double socket, one in the hallway, one in the upstairs landing, and two in the home office. All connect in the basement to the fiber optic terminal, patch panel, switch, and router. Our telephone system also runs over the network cables (using 2 or 4 wires). We have Wi-Fi on the ground floor, and thanks to the wooden structure and MIMO technology, good data rates are possible even with a notebook.
For cameras, it still makes the most sense to use LAN with Power over Ethernet (PoE).

Does the electrician also lay the cables in a way that they can be pulled back out of the conduit pipes? Conduit pipes, good point. I would say,

In the end, 18 Cat 7 cables arrive in the basement and are connected to the patch panel minus the planned four connections leaves fourteen conduits — that sounds like a realistic size.

I would distribute directly from the basement and place the Fritzbox there. You rarely need to access it anyway, so going to the basement is fine. Additionally, I would install a double socket in every basement room, This might mean one more Wi-Fi access point than if the Fritzbox was in the living room, but basically, your network architecture is more appropriate. The control center should be directly at a single starting point.

We’re having the same discussion about electrical outlets For me, this is a major reason why I could go from being a tenant to a homeowner: to create something that eliminates all temporary solutions and compromises, or put more simply: no more extension cords, all outlets installed flush in the walls.
