Building without antenna and SAT-CAT cable without conduit?

Isn't an antenna that old-fashioned cable through which in the 90s you could only receive ARD, ZDF, and some regional channel, right? Are there more channels now? Do you need it?

There are currently around 500 channels, and today you have "Triple Play" consisting of Internet, radio/TV, and telephony. One customer prefers it from the former telephone network provider, another prefers it from the former broadcast network provider, and a third wants both. In any case, to have all three, you only need one of the two. As long as we are talking up to the modem / IAD (something with a dumb name box) from copper (coax), in village electrician speak, that is basically antenna cable. For Telekom, copper would still be twisted pair, but the trend nowadays is fiber optic. Basically, I would also have an electrician from yesteryear, who only understands the buzzword "Cat 7" from modern times, deal only with light current. You have already been pointed to existing entertainment cabling threads.

For this reason, I directly ran a patch cable. It worked wonderfully. Keystone probably could not have been pulled back into the empty conduit.

But beware: If there is a factory-assembled RJ45 at the end, which is probably common with installation cables, it might be too bulky for the access point.

Since we also did not consider a sufficiently large empty conduit, we mounted a thin ring between the ceiling and the access point, which then holds the Keystone module and the end of the short network cable.

Better a hollow box or chisel something out. If necessary, the solution from Opalau also works.

Oh wow, I have to google some words first. We are both computer scientists, but I have never heard of some terms.

I think it will be difficult to teach the electrician to leave a CAT cable hanging from the ceiling. We already have more communication problems with him than I like.
We had considered putting a socket in the hallway and placing the access point either high up on a wall or on a shelf in the hallway. It would also work on the ceiling (it's drywall).

Attach it to the ceiling. If it is suspended, even easier. At that point, you only need a 3cm hole.

Oh wow, I have to look up some words here first. We are both computer scientists, but I have never heard of some terms. ...

let me guess: business informatics specialists or programmers? We have some of those sitting in the company too. They don’t know such things either But they do some really great other stuff! To each their own.
