ᐅ Questions about the home network

Hello,
I have a question for you all. We are planning how to best design the home network and are looking for any additional tips or improvements.

We want to install network cables (Cat-7 cables) throughout the entire house, with a total of 9 double outlets. We plan to use Cat-7 duplex cables and connect them to Cat-6a sockets. We also want to connect the telephone to a network socket and possibly watch TV over the internet later on.

Our router only has 4 Ethernet ports, so we will need a network switch, or are there other options? What should we consider when choosing a switch?
Do we also need a patch panel, or is it not necessary?
Can we buy any Cat-7 duplex cable, or are there specific things to watch out for?

Thanks in advance for your advice.
Best regards

Why CAT7? Why not Cat5? Do you need more than 4 ports for internet access?
You don’t need a patch panel; you can just crimp connectors and plug them in yourself.
What for duplex cables?
Within a house, you can split the eight wires of a Cat cable between 2 outlets!
Unless you want to set up a gigabit network.

Hello, CAT-7 mainly because everyone recommends it and because we want to watch TV over the internet later on.
Yes, we want to install more than 4 network outlets in the house, which is why we are also asking how to connect them properly.
We chose duplex cable to avoid running two separate cables to each outlet.
We prefer to plan with CAT-7 from the start to ensure we have peace of mind for a long time.
We would still be very grateful for any tips.

Who recommends that? The electrician? Friends who believe that a higher Cat rating means better quality?
Cat7 is designed for Gigabit speeds; streaming TV over the Internet already works fine at 16Mbit!!!
I’m not talking about having 4 network outlets, but whether you actually connect more than 4 devices via LAN or if the 4 ports on your router are enough. Maybe you connect several devices via Wi-Fi?
And as I said about duplex cables: if you want 2 outlets, for example for Internet and phone, one cable is sufficient.

Otherwise, you need a switch or hub.
I would use a patch panel for better organization.
I don’t see where there should be differences in the cables, except in color. The specification is determined by the CAT rating. Maybe some cables are stiffer and others more flexible.

The electrician recommends this because it is the future, and after all, we are building a house for the future.
There will be a maximum of 4 devices connected to the internet at the same time, so 4 ports will be enough. However, if you want to connect from another outlet, you first have to switch cables in the utility room, which is not ideal.
Otherwise, we would connect the router to a switch and then go from there to the patch panel, right?
How does it work that from the switch there are multiple ports available?
But if I only run one cable to a double network socket, I only get half the speed each time, so we want to install duplex cables.

Then have your electrician give you the prices for CAT 5! The future, yes, of course, but do you drive a hybrid because of that? That’s also the future. Are you aware of what CAT 7 can do? We won’t reach that level in the private sector for another 20 years. CAT 5 is more than enough, but that’s just my opinion (I work with bandwidths far beyond gigabit).
The idea that the speed is halved is nonsense! You only need 4 wires for Ethernet 1, 2, 3, and 6, and telephone requires 2 wires! Nothing is halved. For gigabit, however, you need all 8 wires.
If you need 4 connections and those frequently change rooms, sure, then a switch.
I don’t understand the question about the slots?!
