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!

Sorry everyone – I didn’t mean to start a heated debate. What I mainly wanted to say is this: When I receive the SIP credentials (username and password for the phone line) from my provider, I only need to consider RJ45 network cabling/Wi-Fi coverage, not additional telephone wiring. Wherever internet access is available, I can simply connect suitable devices. This is especially useful for me in the garden, the basement, and at my neighbor’s house (who happens to be my parents-in-law). If I wanted, I could even set up a phone at my girlfriend’s place – though only my wife would object to that.

That’s the advantage compared to the past when dealing with splitters, ISDN systems, and analog phones. Since I imagine not every homebuilder is aware of what is possible today, I just wanted to share this insight.

Correct
In theory, you could use your smartphone with your landline number from the farthest corner of your garden, where the neighbor’s Wi-Fi is stronger than yours – and you are probably right that the average home builder hasn’t thought of that yet.
