ᐅ Broadband connection / TV, radio, and LAN in every room?

Unfortunately, I am a complete beginner regarding the above-mentioned topic and quite uncertain:

We are currently building our house, which will be connected via a broadband connection from KEVAG Telekom (TV, radio, internet, telephone). I assume the main connection point will be located in the utility room (house without a basement).

In every living area, the following connections should be possible:

- TV / radio

- LAN

- Broadband modem (or do I only need this in the utility room?)

As part of the construction work, all living rooms are to be equipped with Cat 6 network cables (supporting 10 megabits to 1 gigabit), arranged in a star topology running to one chosen room (most likely the utility room).

Do I need any cables besides the Cat 6 network cable in a room to have TV, radio, and internet LAN connections there, for example, separate LAN cables?

What specific types of wall outlets should I have installed in the rooms?

I kindly ask for clear explanations. I am not young anymore and have no knowledge of this subject.

Thank you very much!

@ all,

thank you for your answers.

I understand the following:

- The electrician is the main contact person.

- TV/radio wiring is separate from LAN wiring (each requires its own cabling).

- Cat 7 LAN cables are better than Cat 6.

- Double LAN sockets are preferable to single sockets.

Do I need twice the number of LAN cables for the double sockets (one separate cable per socket), or are the double sockets connected in series like double electrical outlets?

Regards, Gotthilf

Double cables, known as duplex Ethernet cables, are the standard for this purpose. Anything else is outdated.

And insist on installing them in conduit pipes; this is compliant with standards but is often neglected by some old-school electricians. This way, you can replace or modify the cables later if needed.

The CAT7 outlets are still quite expensive.

The question is whether to use Cat7 at all, or to install Cat6 outlets instead. If a really fast connection is needed or can be utilized, you could always upgrade to Cat7 later.

Since when have Cat.7 outlets been available? That must be a fake because RJ45 connectors have contact spacing that is too narrow for Cat.7.

What do you mean by "so fast"? Cat.6 can handle up to 10 Gbps, but the necessary hardware is hardly affordable for most private users. 1 Gbps should be more than enough, and that is easily achievable with standard Cat.6. The reason for using Cat.7 cables in installations is mainly related to shielding and the large number of parallel cables in the conduit.

Wiring in series is not possible. However, the LAN cable has 8 wires, which can theoretically be split into 2 sets of 4 wires each. Many contractors use this method to save money. It works, but limits the usable speed to 100 Mbit instead of 1 Gbit and is therefore not recommended.
